A New Efficient Asymmetric Cryptosystem Based on the Square Root Problem (1207.1157v3)
Published 5 Jul 2012 in cs.IT, cs.CR, and math.IT
Abstract: The square root modulo problem is a known primitive in designing an asymmetric cryptosystem. It was first attempted by Rabin. Decryption failure of the Rabin cryptosystem caused by the 4-to-1 decryption output is overcome efficiently in this work. The proposed scheme (known as the AA_\beta- cryptosystem) has its encryption speed having a complexity order faster than the Diffie-HeLLMan Key Exchange, El-Gammal, RSA and ECC. It can also transmit a larger data set securely when compared to existing asymmetric schemes. It has a simple mathematical structure. Thus, it would have low computational requirements and would enable communication devices with low computing power to deploy secure communication procedures efficiently.
