Toha Key Hardened Function

Ahmad Almorabea

Abstract: TOHA is Key Hardened Function designed in the general spirit of sequential memory- hard function which based on secure cryptographic hash function, the idea behind its design is to make it harder for an attacker to perform some generic attacks and to make it costly as well, TOHA can be used for deriving keys from a master password or generating keys with length of 256-bit to be used in other algorithm schemes, general approach is to use a password and a salt like a normal scheme plus other parameters, and you can think of the salt as an index into a large set of keys derived from the same password, and of course you don’t need to hide the salt to operate.

Category / Keywords: secret-key cryptography / key derivation, password based authentication, KDF, Authentication
