Abstract

Complex structure and low efficiency are the deficiencies exist in the traditional composite encryption algorithm. This paper comes up with an iterative composite encryption algorithm based on TEA and ELGamal. ElGalam is applied to the encryption process using TEA 32-time cyclic iteration by group. This kind of algorithm has better encryption efficiency and higher encryption strength together with smaller amount of keys, simpler operation and more convenient modification method, it totally adapts to an environment which requires high level of security but low consumption of system resource.
