Lyra2: Password Hashing Scheme with improved security against time-memory trade-offs
Eprint
https://eprint.iacr.org/2015/136
Marcos A. Simplicio Jr. Leonardo C. Almeida Ewerton R. Andrade Paulo C. F. dos Santos Paulo S. L. M. Barreto
We present Lyra2, a password hashing scheme (PHS) based on cryptographic sponges. Lyra2 was designed to be strictly sequential (i.e., not easily parallelizable), providing strong security even against attackers that uses...
