Password Hashing Competition - Survey and Benchmark

Password hashing is the common approach for maintaining users’ password-related information that is later used for authentication. A hash for each password is calculated and maintained at the service provider end. When a user logins the service, the hash of the given password is computed and contrasted with the stored hash. If the two hashes match, the authentication is successful. However, in ...

Password-Hashing Status

Computers are used in our everyday activities, with high volumes of users accessing provided services. One-factor authentication consisting of a username and a password is the common choice to authenticate users in the web. However, the poor password management practices are exploited by attackers that disclose the users’ credentials, harming both users and vendors. In most of these occasions t...

Cryptanalytic Time-Memory Tradeoff for Password Hashing Schemes

A cryptanalytic technique known as time-memory tradeoff (TMTO) was proposed by Hellman for finding the secret key of a block cipher. This technique allows sharing the effort of key search between the two extremes of exhaustively enumerating all keys versus listing all possible ciphertext mappings produced by a given plaintext (i.e. table lookups). The TMTO technique has also been used as an eff...

Catena: A Memory-Consuming Password-Scrambling Framework

It is a common wisdom that servers should store the one-way hash of their clients’ passwords, rather than storing the password in the clear. In this paper we introduce a set of functional properties a key-derivation function (password scrambler) should have. Unfortunately, none of the existing algorithms satisfies our requirements and therefore, we introduce a novel and provably secure password...
