Efficiency Enhancement of RSA Cryptosystem using Modified CFEA-Lossless Compression Technique Mandangan, Arif; Ramdan, Raudatul Atiqah The rising of data exchange among people is a wake-up call for the urgency of security. In conjunction to people’s urgency of data security, cryptography is introduced as cryptography conceal private messages andkeep it secure from unauthorized access by using mathematical calculation. The root of this study would be based on Rivest-Shamir-Adleman (RSA) cryptosystem, one of the asymmetric cryptosystems. Because the sizeof and rose as the number of original plaintexts increased, this study attempted to enhance the efficiency of the RSA cryptosystem's encryption and decryption algorithms by employing a modified CFEA compressionapproach.The study was carried out in this dissertation by using different numbers of plaintext to fixed size and comparing the results between RSA cryptosystem and modified RSA cryptosystem by using Maple 2021software as measuring tools. The results indicate that the modified CFEA compression approach is able to reduce the two plaintexts yet not reducing the execution time for the encryption and decryption procedures.
