Abstract:
In this paper, we introduce a new scheme based on the hardness of factoring integers of the shape $N=p^{2}q$. Our scheme uses a combination of modular linear and modular squaring. We show that the decryption is 1-to-1 which is a great advantage over Rabin's cryptosystem. Its encryption speed has a complexity order faster than RSA and ECC. For decryption, its speed is better than RSA and is marginally behind ECC. Constructed using a simple mathematical structure, it has low computational requirements and would enable communication devices with low computing power to deploy secure communication procedures efficiently.

Keywords: Integer factorization problem, square root problem, asymmetric cryptosystem
