Abstract

Two basic techniques in cryptography are symmetric and asymmetric. Algorithm Caesar Cipher and Data Encryption Standard includes a symmetric algorithm, while the RSA algorithm includes an asymmetric algorithm. Algorithm hybrid which combines symmetric and asymmetric algorithms is formed to get the advantages of each algorithm. In the encryption and decryption process, high security is the basic benchmark. High data security can be measured by several parameters such as encryption and decryption speed, CPU usage and memory usage. In this study use a combination of algorithms with encryption that starts with the algorithm Caesar Cipher, Data Encryption Standard, and RSA and substantiated by decryption starting with the RSA algorithm, Data Encryption Standard, and Caesar Cipher. This study compare data security with a comparison of a combination of algorithms and a single algorithm. By combining the Caesar Cipher algorithm, Data Encryption Standard, and RSA you can save time, CPU and memory usage. In the combination of algorithms when encryption takes 7.9 seconds, CPU usage is 27.4%, memory used is 8533 mb and when encryption takes 8.4 seconds, CPU usage is 27.8%, memory used is 8527 mb .
