Researchers have produced a collision in iOS’s built-in hash function, raising new concerns about Apple’s CSAM-scanning system — but Apple says the finding does not threaten the integrity of the ...

Many organizations have been replacing the MD5 hash algorithm with the SHA-1 hash function, but can the MD5 hash algorithm still be used securely? MD5 (Message-Digest algorithm 5) is a cryptographic ...

SHA-256 produces a fixed 256-bit output from an input of any size, and Bitcoin applies it twice to block data. Ethereum chose ...

Cryptographers solved a version of this decades ago with a commit-reveal scheme. One party locks in a secret before the other acts, publishes proof of that commitment, and only reveals the secret ...

In the previous blog post, “Securing Offload Engines for a Robust Secure SoC System,” we briefly looked at some of the methods employed for achieving embedded security, i.e., cryptography, hardware ...
