Abstract

Security in the field of Information Technology is the defense of digital information along with its assets against internal and/or external malicious and accidental threats. To secure such valuable information, cryptography is used. A cryptography or encryption algorithm is the process of transforming sensitive data into confounding data in such a way that the person or the machine with a key can decode the hidden information. Among these algorithms is the Vigenere matrix. In this article, a hybrid approach is used in the encryption algorithm. This approach implements the matrix manipulation principle and Base94 encoding algorithm. In order to measure the performance of the proposed algorithm, the Avalanche Effect is used. The result of the study shows a significant high avalanche effect compared to the traditional Vigenere cryptosystem.
