Performance Comparison of Symmetries Encryption Algorithm AES and DES With Raspberry Pi

This study aims to analyze the performance of symmetrical encryption algorithms between the AES and DES algorithms, and the use of mini PC devices such as Raspberry Pi. It aims to find algorithms that excel in performance. The performance, which is a measure is the time and memory used to encrypt and decrypt with the same key - the method used in research with an experimental approach. Where experimental done on Raspberry PI with PHP programming language, the results of this study indicate that the AES algorithm requires a shorter time in encrypting messages compared to the DES algorithm. The AES algorithm uses a larger memory capacity in encrypting messages compared to the DES algorithm. The AES algorithm is recommended to use because in terms of security AES has a more significant number of keys that is 128 bits while the DES algorithm has a key length of 64 bits or half of the number of keys in the AES Algorithm. The results of the comparison of the two algorithms can be used as a reference where two encryption algorithms are compatible with the applications and devices developed.
