Understand the term self-signed certificates 2. Creating self-signed certificates 3. Configuring an asp.net web application to use SSL, that is use HTTPS instead of HTTP 4. Importing and exporting certificates What are self signed certificates A self-signed certificate is an identity certificate that is signed by its own creator. Certificates are signed by Certificate Authority. In general self signed certificates are fine for testing purposes and not for production use. Creating self-signed certificates There are several ways to create self signed test certificates. Let us explore 2 of the easier options available. The easiest and simpler approach is to use IIS to create these certificates. In IIS 7.5 1. Click on the "Server Name" 2. Double click "Server Certificates" feature 3. Click on "Create Self Signed Certificate" link, under "Actions" 4. Specify a friendly name for the certificate and click OK. The friendly name is not part of the certificate itself, but is used by the server administrator to easily distinguish the certificate. The generated test certificate, is also automatically installed into the certificate store. MakeCert.exe tool can be used as another way to generate, test certificates. The following link from microsoft explains, various options that can be used with this tool. This is a command line tool and must be run from visual studio command prompt. http://msdn.microsoft.com/en-us/library/bfsktky3.aspx Makecert -r -pe -n "CN=YourComputerName" -b 01/01/2000 -e 01/01/2100 -ss my -sr localMachine -sky exchange -sp "Microsoft RSA SChannel Cryptographic Provider" -sy 12 Note: Replace YourComputerName, with the name of your computer. Associating an asp.net web application with a specific certificate Add HTTPS site binding, if it is not already present 1. Open IIS 2. Expand the "Server Name" 3. Expand "Sites" 4. Select "Default Web Site" 5. Click "Binding" under "Edit Site" in "Actions" pane. 6. In the "Site Bindings" window, Click "Add" 7. Select Type = "https" and the SSL Certificate and click "OK" 8. Click "Close" on "Site Bindings" window At this point, you will be able to access your application using both HTTP and HTTPS protocol. When the site is accessed over HTTPS, you may receive a browser warning about the authenticity of the website. In a later video session we will discuss about resolving this. If you want to dis-allow, access over HTTP protocol there are 2 ways First Way: Remove HTTP binding at the IIS Server level. This option will prevent all the web applications, running on that server to use only HTTPS binding. Second Way: Let both the bindings be available at the server level and configure SSL settings at an application or web site level. 1. Select your web application in IIS 2. Double click "SSL Settings" from the features window 3. Make sure "Require SSL" checkbox is checked. 4. Click "Apply" under "Actions" pane Now, if you try to access the application using HTTP instead of HTTPS, you will get an error HTTP Error 403.4 - Forbidden The page you are trying to access is secured with Secure Sockets Layer (SSL) Use Import and Export feature of IIS to import and export certificates

Post-Quantum Key Exchange for the TLS Protocol from the Ring Learning with Errors Problem
Post-Quantum Key Exchange for the TLS Protocol from the Ring Learning with Errors Problem Douglas Stebila Presented at the 2015 IEEE Symposium on Security & Privacy May 18--20, 2015 San Jose, CA http://www.ieee-security.org/TC/SP2015/ ABSTRACT Lattice-based cryptographic primitives are believed to offer resilience against attacks by quantum computers. We demonstrate the practicality of post-quantum key exchange by constructing cipher suites for the Transport Layer Security (TLS) protocol that provide key exchange based on the ring learning with errors (R-LWE) problem, we accompany these cipher suites with a rigorous proof of security. Our approach ties lattice-based key exchange together with traditional authentication using RSA or elliptic curve digital signatures: the post-quantum key exchange provides forward secrecy against future quantum attackers, while authentication can be provided using RSA keys that are issued by today's commercial certificate authorities, smoothing the path to adoption. Our cryptographically secure implementation, aimed at the 128-bit security level, reveals that the performance price when switching from non-quantum-safe key exchange is not too high. With our R-LWE cipher suites integrated into the Open SSL library and using the Apache web server on a 2-core desktop computer, we could serve 506 RLWE-ECDSA-AES128-GCM-SHA256 HTTPS connections per second for a 10 KiB payload. Compared to elliptic curve Diffie-Hellman, this means an 8 KiB increased handshake size and a reduction in throughput of only 21%. This demonstrates that provably secure post-quantum key-exchange can already be considered practical.

Recover a RSA Private Key From a TLS Session With Perfect Forward Secrecy
by Marco Ortisi They always taught us that the only thing that can be pulled out from a SSL/TLS session using strong authentication and latest Perferct Forward Secrecy ciphersuites is the public key of the certificate exchanged during the handshake - an insufficient condition to place a MiTM attack without to generate alarms on the validity of the TLS connection and certificate itself. Anyway, this is not always true. In certain circumstances it is possible to derive the private key of server regardless of the size of the used modulus. Even RSA keys of 4096 bits can be factored at the cost of a few CPU cycles and computational resources. All that needed is the generation of a faulty digital signature from server, an event that can be observed when occurring certain conditions such as CPU overheating, RAM errors or other hardware faults. Because of these premises, devices like firewall, switch, router and other embedded appliances are more exposed than traditional IT servers or clients. During the talk, the author will explain the theory behind the attack, how common the factors are that make it possible and his custom pratical implementation of the technique. At the end, a proof-of-concept, able to work both in passive mode (i.e. only by sniffing the network traffic) and in active mode (namely, by participating directly in the establishment of TLS handshakes), will be released.

Key Confirmation in Key Exchange: A Formal Treatment and Implications for TLS 1.3
Key Confirmation in Key Exchange: A Formal Treatment and Implications for TLS 1.3 Felix Günther (Technische Universität Darmstadt) Presented at the 2016 IEEE Symposium on Security & Privacy May 23–25, 2016 San Jose, CA http://www.ieee-security.org/TC/SP2016/ ABSTRACT Key exchange protocols allow two parties at remote locations to compute a shared secret key. The common security notions for such protocols are secrecy and authenticity, but many widely deployed protocols and standards name another property, called key confirmation, as a major design goal. This property should guarantee that a party in the key exchange protocol is assured that another party also holds the shared key. Remarkably, while secrecy and authenticity definitions have been studied extensively, key confirmation has been treated rather informally so far. In this work, we provide the first rigorous formalization of key confirmation, leveraging the game-based security framework well-established for secrecy and authentication notions for key exchange. We define two flavors of key confirmation, full and almost-full key confirmation, taking into account the inevitable asymmetry of the roles of the parties with respect to the transmission of the final protocol message. These notions capture the strongest level of key confirmation reasonably expectable for the two communication partners of the key exchange. We demonstrate the benefits of having precise security definitions for key-confirmation by applying them to the next version of the Transport Layer Security (TLS) protocol, version 1.3, currently developed by the Internet Engineering Task Force (IETF). Our analysis shows that the full handshake as specified in the TLS 1.3 draft draft-ietf-tls-tls13-10 achieves desirable notions of key confirmation for both clients and servers. While key confirmation is generally understood and in the TLS 1.3 draft described as being obtained from the Finished messages exchanged, interestingly we can show that the full TLS 1.3 handshake provides key confirmation even without those messages, shedding a formal light on the security properties different handshake messages entail. We further demonstrate the usefulness of rigorous definition by revisiting a folklore approach to establish key confirmation (as discussed for example in SP 800-56A of NIST). We provide a formalization as a generic protocol transformation and show that the resulting protocols enjoy strong key confirmation guarantees, thus confirming its beneficial use in both theoretical and practical protocol designs.

Security of the J-PAKE Password-Authenticated Key Exchange Protocol
Security of the J-PAKE Password-Authenticated Key Exchange Protocol Fabrice Benhamouda Presented at the 2015 IEEE Symposium on Security & Privacy May 18--20, 2015 San Jose, CA http://www.ieee-security.org/TC/SP2015/ ABSTRACT J-PAKE is an efficient password-authenticated key exchange protocol that is included in the Open SSL library and is currently being used in practice. We present the first proof of security for this protocol in a well-known and accepted model for authenticated key-exchange, that incorporates online and offline password guessing, concurrent sessions, forward secrecy, server compromise, and loss of session keys. This proof relies on the Decision Square Diffie-Hellman assumption, as well as a strong security assumption for the non-interactive zero-knowledge (NIZK) proofs in the protocol (specifically, simulation-sound extractability). We show that the Schnorr proof-of-knowledge protocol, which was recommended for the J-PAKE protocol, satisfies this strong security assumption in a model with algebraic adversaries and random oracles, and extend the full J-PAKE proof of security to this model. Finally, we show that by modifying the recommended labels in the Schnorr protocol used in J-PAKE, we can achieve a security proof for J-PAKE with a tighter security reduction.

What is TRANSPORT LAYER SECURITY? What does TRANSPORT LAYER SECURITY mean? TRANSPORT LAYER SECURITY meaning - TRANSPORT LAYER SECURITY definition - TRANSPORT LAYER SECURITY explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), both frequently referred to as "SSL", are cryptographic protocols that provide communications security over a computer network. Several versions of the protocols find widespread use in applications such as web browsing, email, Internet faxing, instant messaging, and voice-over-IP (VoIP). Websites use TLS to secure all communications between their servers and web browsers. The Transport Layer Security protocol aims primarily to provide privacy and data integrity between two communicating computer applications.:3 When secured by TLS, connections between a client (e.g., a web browser) and a server (e.g., wikipedia.org) have one or more of the following properties: The connection is private (or secure) because symmetric cryptography is used to encrypt the data transmitted. The keys for this symmetric encryption are generated uniquely for each connection and are based on a shared secret negotiated at the start of the session (see TLS handshake protocol). The server and client negotiate the details of which encryption algorithm and cryptographic keys to use before the first byte of data is transmitted (see Algorithm below). The negotiation of a shared secret is both secure (the negotiated secret is unavailable to eavesdroppers and cannot be obtained, even by an attacker who places themselves in the middle of the connection) and reliable (no attacker can modify the communications during the negotiation without being detected). The identity of the communicating parties can be authenticated using public-key cryptography. This authentication can be made optional, but is generally required for at least one of the parties (typically the server). The connection ensures integrity because each message transmitted includes a message integrity check using a message authentication code to prevent undetected loss or alteration of the data during transmission.:3 In addition to the properties above, careful configuration of TLS can provide additional privacy-related properties such as forward secrecy, ensuring that any future disclosure of encryption keys cannot be used to decrypt any TLS communications recorded in the past. TLS supports many different methods for exchanging keys, encrypting data, and authenticating message integrity (see Algorithm below). As a result, secure configuration of TLS involves many configurable parameters, and not all choices provide all of the privacy-related properties described in the list above (see authentication and key exchange table, cipher security table, and data integrity table). Attempts have been made to subvert aspects of the communications security that TLS seeks to provide and the protocol has been revised several times to address these security threats (see Security). Developers of web browsers have also revised their products to defend against potential security weaknesses after these were discovered (see TLS/SSL support history of web browsers.) The TLS protocol comprises two layers: the TLS record protocol and the TLS handshake protocol. TLS is a proposed Internet Engineering Task Force (IETF) standard, first defined in 1999 and updated in RFC 5246 (August 2008) and RFC 6176 (March 2011). It builds on the earlier SSL specifications (1994, 1995, 1996) developed by Netscape Communications for adding the HTTPS protocol to their Navigator web browser.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ SSL acceleration (TLS acceleration) is a method of offloading processor-intensive public-key encryption for Transport Layer Security (TLS) and its predecessor Secure Sockets Layer (SSL) to a hardware accelerator. Typically this means having a separate card that plugs into a PCI slot in a computer that contains one or more co-processors able to handle much of the SSL processing. SSL accelerators may use off the shelf CPUs, but most use custom ASICs and RISC chips to do most of the difficult computational work. The most computationally expensive part of an SSL session is the SSL handshake, where the SSL server (usually an SSL webserver) and the SSL client (usually a web browser) agree on a number of parameters that establish the security of the connection. Part of the role of the SSL handshake is to agree on session keys (symmetric keys, used for the duration of a given session), but the encryption and signature of the SSL handshake messages itself is done using asymmetric keys (contained in the certificates), which requires more computational power than the symmetric cryptography used for the encryption/decryption of the session data. Typically a hardware SSL accelerator will offload processing of the SSL handshake while leaving it to the server software to process the less intense symmetric cryptography of the actual SSL data exchange, but some accelerators handle all SSL operations and terminate the SSL connection, thus leaving the server seeing only unencrypted connections. Modern x86 CPUs support Advanced Encryption Standard (AES) encoding and decoding in hardware, using the AES instruction set proposed by Intel in March 2008. Allwinner Technology provides a hardware cryptographic accelerator in its A10, A20, A30 and A80 ARM system-on-chip series, and all ARM CPUs have acceleration in the later ARMv8 architecture. The accelerator provides the RSA public-key algorithm, several widely used symmetric-key algorithms, cryptographic hash functions, and a cryptographically secure pseudo-random number generator.[1] TLS 1 was first defined in RFC 2246 in January 1999 as an upgrade to SSL Version 3. Because TLS is essentially an updated form of SSL, TLS session acceleration is essentially the same thing as SSL acceleration. As stated in the RFC, "the differences between this protocol and SSL 3 are not dramatic, but they are significant enough that TLS 1 and SSL 3 do not interoperate." TLS 1 does include a means by which a TLS implementation can downgrade the connection to SSL 3. The current version of TLS (1.2) was defined in RFC 5246 in August 2008. It is based on the earlier TLS 1.1 specification.

F5 Security Vignette: SSL Renegotiation
The premise of the SSL Renegotiation DOS attack is simple: "An SSL/TLS handshake requires at least 10 times more processing power on the server than on the client". If a client machine and server machine were equal in RSA processing power, the client could overwhelm the server by sending ten times as many SSL handshake requests as the server could service. The counter measure against the attacks was to write an iRule to limit renegotiation requests to 5 per minute per session. If we were going to sum up the role of security in corporate IT today we'd have to say it's to "be prepared." This series looks at many of those security concerns which can be addressed proactively, before they are exploited or become a fire drill.
