OpenSSL After Heartbleed by Rich Salz & Tim Hudson, OpenSSL
OpenSSL After Heartbleed - Rich Salz & Tim Hudson, OpenSSL OpenSSL is the most widely-deployed TLS library in the world. A simple programming mistake—failing to check an output length—shook up the project and generated a “re-key the Internet” event. This session will discuss what has happened within the project since then: an expanded team, increased transparency, more rigorous development processes, and greatly increased vitality. About Tim Hudson Tim Hudson has been involved in system security for more than 20 years. Tim's day job is as the CTO at Cryptsoft where he provides advice and guidance on security technology design and architecture. Tim is involved in KMIP, PKCS#11, FIPS140, OASIS and SNIA and is a long time OpenSSL user and is also an OpenSSL team member. About Rich Salz Rich has spoken at RSA, Java-One, and LF Collab Summit, among others. He works at Akamai, helping to make the configuration simpler and more secure by default. He is a member of the OpenSSL development team. He co-chairs the IETF ACME (LetsEncrypt protocol) and Curdle (new ECC curve usages) working groups.

Guide to Rails Encrypted Credentials
Starting in Rails 5.2+, the framework now comes with a built in way to encrypt configuration credentials and environment variables. In previous versions an application would need to use a tool such as dotenv or figaro, and you could NEVER include the variable values in version control for security reasons. However, now all of the credentials are encrypted, and a single master key can decrypt them. This means that your team can add the credentials to version control and share them with much more ease. This video walks through how to: view, edit, and query the credentials, along with how to call them from the console and the application. And finally I show how to configure Heroku to work with the credentials. Here is a link to a cheat sheet that shows the common commands needed to work with Rails encrypted credentials: http://www.dailysmarty.com/posts/cheat-sheet-for-working-with-rails-encrypted-credentials

A Messy State of the Union: Taming the Composite State Machines of TLS
A Messy State of the Union: Taming the Composite State Machines of TLS Karthikeyan Bhargavan Presented at the 2015 IEEE Symposium on Security & Privacy May 18--20, 2015 San Jose, CA http://www.ieee-security.org/TC/SP2015/ ABSTRACT Implementations of the Transport Layer Security (TLS) protocol must handle a variety of protocol versions and extensions, authentication modes, and key exchange methods. Confusingly, each combination may prescribe a different message sequence between the client and the server. We address the problem of designing a robust composite state machine that correctly multiplexes between these different protocol modes. We systematically test popular open-source TLS implementations for state machine bugs and discover several critical security vulnerabilities that have lain hidden in these libraries for years, and have now finally been patched due to our disclosures. Several of these vulnerabilities, including the recently publicized FREAK flaw, enable a network attacker to break into TLS connections between authenticated clients and servers. We argue that state machine bugs stem from incorrect compositions of individually correct state machines. We present the first verified implementation of a composite TLS state machine in C that can be embedded into OpenSSL and accounts for all its supported cipher suites. Our attacks expose the need for the formal verification of core components in cryptographic protocol libraries, our implementation demonstrates that such mechanized proofs are within reach, even for mainstream TLS implementations.
What is CRYPTOGRAPHIC SERVICE PROVIDER? What does CRYPTOGRAPHIC SERVICE PROVIDER mean? CRYPTOGRAPHIC SERVICE PROVIDER meaning - CRYPTOGRAPHIC SERVICE PROVIDER definition - CRYPTOGRAPHIC SERVICE PROVIDER 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 In Microsoft Windows, a Cryptographic Service Provider (CSP) is a software library that implements the Microsoft CryptoAPI (CAPI). CSPs implement encoding and decoding functions, which computer application programs may use, for example, to implement strong user authentication or for secure email. CSPs are independent modules that can be used by different applications. A user program calls CryptoAPI functions and these are redirected to CSPs functions. Since CSPs are responsible for implementing cryptographic algorithms and standards, applications do not need to be concerned about security details. Furthermore, one application can define which CSP it is going to use on its calls to CryptoAPI. In fact, all cryptographic activity is implemented in CSPs. CryptoAPI only works as a bridge between the application and the CSP. CSPs are implemented basically as a special type of DLL with special restrictions on loading and use. Every CSP must be digitally signed by Microsoft and the signature is verified when Windows loads the CSP. In addition, after being loaded, Windows periodically re-scans the CSP to detect tampering, either by malicious software such as computer viruses or by the user him/herself trying to circumvent restrictions (for example on cryptographic key length) that might be built into the CSP's code. To obtain a signature, non-Microsoft CSP developers must supply paperwork to Microsoft promising to obey various legal restrictions and giving valid contact information. As of circa 2000, Microsoft did not charge any fees to supply these signatures. For development and testing purposes, a CSP developer can configure Windows to recognize the developer's own signatures instead of Microsoft's, but this is a somewhat complex and obscure operation unsuitable for nontechnical end users. The CAPI/CSP architecture had its origins in the era of restrictive US government controls on the export of cryptography. Microsoft's default or "base" CSP then included with Windows was limited to 512-bit RSA public-key cryptography and 40-bit symmetric cryptography, the maximum key lengths permitted in exportable mass market software at the time. CSPs implementing stronger cryptography were available only to U.S. residents, unless the CSPs themselves had received U.S. government export approval. The system of requiring CSPs to be signed only on presentation of completed paperwork was intended to prevent the easy spread of unauthorized CSPs implemented by anonymous or foreign developers. As such, it was presented as a concession made by Microsoft to the government, in order to get export approval for the CAPI itself. After the Bernstein v. United States court decision establishing computer source code as protected free speech and the transfer of cryptographic regulatory authority from the U.S. State Department to the more pro-export Commerce Department, the restrictions on key lengths were dropped, and the CSPs shipped with Windows now include full-strength cryptography. The main use of third-party CSPs is to interface with external cryptography hardware such as hardware security modules (HSM) or smart cards.

Black Hat USA 2012 - Torturing OpenSSL
By: Valeria Bertacco For any computing system to be secure, both hardware and software have to be trusted. If the hardware layer in a secure system is compromised, not only it is possible to extract secret information about the software, but it is also extremely difficult for the software to detect that an attack is underway. This talk will detail a complete end-to-end security attack to on a microprocessor system and will demonstrate how hardware vulnerabilities can be exploited to target systems that are software-secure. Specifically, we present a side-channel attack to the RSA signature algorithm by leveraging transient hardware faults at the server. Faults may be induced via voltage-supply variation, temperature variation, injection of single-event faults, etc. When affected by faults, the server produces erroneous RSA signatures, which it returns to the client. Once a sufficient number of erroneously signed messages is collected at the client end, we filter those that can leak private key information and we use them to extract the private key. We developed an algorithm to extract the private RSA key from messages affected by single-bit faults in the multiplication during Fixed Window Exponentiation (FWE), that is, the standard exponentiation algorithm used in OpenSSL during RSA signing. Our algorithm was inspired by a solution developed by Boneh, et al. for the Chinese Remainder Theorem (CRT) [D. Boneh, R. DeMillo, and R. Lipton. On the importance of eliminating errors in cryptographic computations. Journal of Cryptology, Dec 2001], an algorithm particularly prone to attacks. Depending of the window size used in the encryption algorithm, it is possible to extract 4-6 bits of the private key from an erroneously signed message. Our attack is perpetrated using a FPGA platform implementing a SPARC-based microprocessor running unmodified Linux and the OpenSSL authentication library. The server provides 1024-bits RSA authentication to a client we control via Ethernet connection. Faults are injected by inducing variations in the supply voltage on the FPGA platform or by subjecting the server to high temperatures. Our client collects a few thousands signed messages, which we transfer to an 80-machines computing pool to compute the private RSA key in less than 100 hours. Note that our attack does not require access to the victim system's internal components, but simply proximity to it. Moreover, it is conceivable that an attack leveraging solely high temperatures can be carried out on machines in a remote poorly-conditioned server room. Finally, the attack does not leave any trail of the attack in the victim machine, and thus it cannot be detected. The presentation includes a live demo of the attack on an FPGA platform implementing a SPARC system. The system is powered via a voltage controller, used to induce variations in the supply voltage. The server is simplified to use a 128-bits private key so that the attack can be perpetrated during the briefing.

The BEAST Wins Again: Why TLS Keeps Failing to Protect HTTP
By Antoine Delignat-Lavaud "SSL has been around for decades and yet it keeps happening: new attacks are being discovered against TLS at a steady rate. The past year has seen its share of rogue CA certificates and critical vulnerabilities in TLS libraries that we have come to expect. In this talk, I will present no less than three new attacks against the use of TLS on the web. The first one relies on a long-known cryptographic weakness in the protocol that can be combined with long-known issues in TLS implementations to re-enable a flavor of the 2009 renegotiation attack that was thought to be fixed. The second one exploits the truncation weakness known since SSL2 but left unsolved to bypass anti-stripping defenses (strict transport security) and steal secure cookies. The last one exploits vulnerabilities in the deployment of HTTPS, in particular, how HTTP servers process requests and manage certificates and sessions, to reach the holy grail of TLS attacks: full server impersonation of several thousands of websites, including Microsoft, Apple, Twitter, PayPal. The three attacks have strong common points: they rely on an attacker that operates both at the TLS and HTTP levels, and they exploit misunderstandings and false assumptions between TLS libraries and applications. In the course of this talk, you will learn about the full capabilities of the ""beastly"" attacker that operates jointly at the transport and application levels and how they can be exploited. You will also learn how to configure your HTTPS server to avoid being vulnerable to our virtual host confusion attacks, for which no simple universal fix exists. Lastly, I will try to disprove some misconceptions about TLS and privacy in the context of powerful network attackers."

Crypto Defenses for Real-World System Threats - Kenn White - Ann Arbor
Modern encryption techniques provide several important security properties, well known to most practitioners. Or are they? What are in fact the guarantees of, say, HTTPS TLS cipher suites using authenticated encryption, IPSec vs. SSL VPNs, Property Preserving Encryption, or token vaults? We live in an era of embedded Hardware Security Modules that cost less than $1 in volume, and countless options now exist for encrypting streaming network data, files, volumes, and even entire databases. Let's take a deep dive into the edge of developed practice to discuss real-world threat scenarios to public cloud and IoT data, and look closely at how we can address specific technical risks with our current encryption toolkits. Advanced math not required. Bio: Kenneth White is a security researcher whose work focuses on networks and global systems.
