| | | | | You may have seen the preprint posted today by Lenstra et al. about entropy problems in public keys. Zakir Durumeric, Eric Wustrow, Alex Halderman, and I have been waiting to talk about some similar results. We will be publishing a full paper after the relevant manufacturers have been notified. Meanwhile, we'd like to give a more complete explanation of what's really going on. We have been able to remotely compromise about 0.4% of all the public keys used for SSL web site security. The keys we were able ... | |

| | | | | [AI summary] The article discusses the use of /dev/random and /dev/urandom in Linux systems for generating random numbers. It highlights that /dev/urandom is generally preferred over /dev/random due to its non-blocking nature and sufficient cryptographic security. The article also addresses misconceptions in the man pages and emphasizes that /dev/urandom is safe for most applications, including cryptographic uses, as long as the initial seeding is done properly. It mentions that while /dev/random is considered a legacy interface, it's not always necessary, and modern Linux distributions and syscalls like getrandom(2) provide better alternatives. | |
