Encryption-Decryption is one form of securing text data, images and sound in order to minimize data stealing, attack, etc. The purpose of this study is to modified encryption-decryption keys of Vigenere cipher.Based on experiment show that multi-cycle keyencryption-decryption have been implemented. Meanwhile, the best MAE values of final encryption process of 56.837 and final decryption process of 0. In other words, the modification of key is more efficient and effective for data security. Furthermore, the multi-cycle key encryption-decryption optimizing using metaheuristics as one of the future works that can be conducted in order to investigate the best encryption-decryption especially using Vigenere cipher.
