Statistical Cryptanalysis of ElGamal Cryptosystem for measuring security in disruptive technology

ElGamal encryption is one of the encryption processes which employs randomization in the encryption procedure. In this paper, we applied cryptanalysis to Elgamal cryptosystem. Cryptanalysis is the study of cryptosystems to understand how they work and look for weaknesses and improve the system and algorithms that are used in that system. We have done entropy analysis, floating frequency analysis, histogram, N-gram, autocorrelation, and periodicity analysis using crypTool
