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 ...
We show attacks on five data-independent memory-hard functions (iMHF) that were submitted to the password hashing competition. Informally, an MHF is a function which cannot be evaluated on dedicated h...
In this document we present an overview of the background to and goals of the Password Hashing Competition (PHC) as well as the design of its winner, Argon2, and its security requirements and proper...
M3dcrypt is a password hashing function built around the Advanced Encryption Standard (AES) algorithm and the arcfour pseudorandom function. It uses up to 256-bit pseudorandom salt values and suppor...
Password-based authentication has been widely deployed in practice due to its simplicity and efficiency. Storing passwords and deriving cryptographic keys from passwords in a secure manner are crucial...
In this work we provide an overview of the candidates of the Password Hashing Competition (PHC) regarding to their functionality, e.g., client-independent update and server relief, their security, e...
Password Hashing, a technique commonly implemented by a server to protect passwords of clients, by performing a one-way transformation on the password, turning it into another string called the has...
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 again...
In this work we have analyzed some password hashing schemes for performance under various settings of time and memory complexities. We have attempted to benchmark the said algorithms at similar leve...
Password hashing is the common approach for maintaining userspassword-related information that is later used for authentication. A hash for each password is calculated and maintained at the servic...
Memory-hard functions are becoming an important tool in the design of password hashing schemes, cryptocurrencies, and more generic proof-of-work primitives that are x86-oriented and can not be comput...
