Rabin and ElGamal Cryptosystem for a secured communication: A Detailed Cryptanalysis

Rabin and ElGamal are famous asymmetric key cryptography aside from that of RSA. Rabin and ElGamal are asymmetric cryptography algorithms that make use of two exceptional keys for encryption and decryption. This paper is novel in finding cryptanalysis of both of these algorithms. The statistical analysis we did are entropy evaluation, histogram, Ngram, floating frequency, autocorrelation and periodicity analysis with CrypTool.
