The Crypto Wars have been waging off-and-on for a quarter-century. On one side is law enforcement, which wants to be able to break encryption, to access devices and communications of terrorists and criminals. On the other are almost every cryptographer and computer security expert, repeatedly explaining that there’s no way to provide this capability without … Read More “Cybersecurity for the Public Interest” »

This is interesting research: “On the Security of the PKCS#1 v1.5 Signature Scheme“: Abstract: The RSA PKCS#1 v1.5 signature algorithm is the most widely used digital signature scheme in practice. Its two main strengths are its extreme simplicity, which makes it very easy to implement, and that verification of signatures is significantly faster than for … Read More “Evidence for the Security of PKCS #1 Digital Signatures” »

New Findings About Prime Number Distribution Almost Certainly Irrelevant to Cryptography

Lots of people are e-mailing me about this new result on the distribution of prime numbers. While interesting, it has nothing to do with cryptography. Cryptographers aren’t interested in how to find prime numbers, or even in the distribution of prime numbers. Public-key cryptography algorithms like RSA get their security from the difficulty of factoring … Read More “New Findings About Prime Number Distribution Almost Certainly Irrelevant to Cryptography” »

Quantum Computing and Cryptography

Quantum computing is a new way of computing — one that could allow humankind to perform computations that are simply impossible using today’s computing technologies. It allows for very fast searching, something that would break some of the encryption algorithms we use today. And it allows us to easily factor large numbers, something that would … Read More “Quantum Computing and Cryptography” »

Interesting research on a version of RSA that is secure against a quantum computer: Post-quantum RSA Daniel J. Bernstein, Nadia Heninger, Paul Lou, and Luke Valenta Abstract: This paper proposes RSA parameters for which (1) key generation, encryption, decryption, signing, and verification are feasible on today’s computers while (2) all known attacks are infeasible, even … Read More “Post-Quantum RSA” »

Security Orchestration and Incident Response

Last month at the RSA Conference, I saw a lot of companies selling security incident response automation. Their promise was to replace people with computers ­– sometimes with the addition of machine learning or other artificial intelligence techniques ­– and to respond to attacks at computer speeds. While this is a laudable goal, there’s a … Read More “Security Orchestration and Incident Response” »
