Really interesting research into the structure of prime numbers. Not immediately related to the cryptanalysis of prime-number-based public-key algorithms, but every little bit matters.
Read moreMatthew Green wrote a really good blog post on what Telegram’s encryption is and is not. EDITED TO ADD (8/28): Another good explainer from Kaspersky.
Read moreReally interesting article on the ancient-manuscript scholars who are applying their techniques to the Voynich Manuscript.
No one has been able to understand the writing yet, but there are...
Read moreA group of cryptographers have analyzed the eiDAS 2.0 regulation (electronic identification and trust services) that defines the new EU Digital Identity Wallet.
Read moreInteresting paper about a German cryptanalysis machine that helped break the US M-209 mechanical ciphering machine. The paper contains a good description of how the M-209 works.
Read moreInteresting summary of various ways to derive the public key from digitally signed files. Normally, with a signature scheme, you have the public key and want to know whether a...
Read moreThis is really neat demo of the security problems arising from reusing nonces with a symmetric cipher in GCM mode.
Read moreThe Polish Embassy has posted a series of short interview segments with Marian Rejewski, the first person to crack the Enigma. Details from his biography.
Read moreA new paper presents a polynomial-time quantum algorithm for solving certain hard lattice problems. This could be a big deal for post-quantum cryptographic algorithms, since many of them...
Read moreLast week, I posted a short memorial of Ross Anderson. The Communications of the ACM asked me to expand it. Here’s the longer version. EDITED TO ADD (4/11): Two weeks...
