Chaotic hash functions represent a cutting‐edge convergence between nonlinear dynamics and cryptographic science. These functions employ chaotic maps—mathematical systems that exhibit extreme ...

Researchers have demonstrated new collision attacks against SHA-1 and MD5 implementations in TLS, IKE and SSH. If you’re hanging on to the theory that collision attacks against SHA-1 and MD5 aren’t ...

For more than six years, the SHA1 cryptographic hash function underpinning Internet security has been at death’s door. Now it’s officially dead, thanks to the submission of the first known instance of ...
