A secured Cryptographic Hashing Algorithm

, 2010
Cryptographic hash functions for calculating the message digest of a message has been in practical use as an effective measure to maintain message integrity since a few decades. This message digest is unique, irreversible and avoids all types of collisions for any given input string.

Secure and Fast Hashing Algorithm with Multiple Security Levels

Journal of Software, 2009
We propose a new secure and fast hashing algorithm with multiple security levels (SFHA-MSL). It is based on the generic 3C (3 compressions) construction and the 3C-X (3C XOR) hash function which is the simplest and efficient variant of the generic 3C hash function and it is the simplest modification to the Merkle-Damgard (M-D) iterated construction ...

Chosen-ciphertext security from subset sum [PDF]

, 2015
We construct a public-key encryption (PKE) scheme whose security is polynomial-time equivalent to the hardness of the Subset Sum problem. Our scheme achieves the standard notion of indistinguishability against chosen-ciphertext attacks (IND-CCA) and can
