The development of computer and telecommunications technology has experienced the significant change in progress. It can be seen that technology has become a necessity because technological advances can accomplish tasks quickly, accurately, and efficiently. In line with the development of these technologies, it increasingly changes the way people communicate. There needs to be security protection to protect data from the threat of wild parties. Cryptography is the right method to secure data. One method that can be used is the Advanced Encryption Standard (AES). This method is an excellent classical cryptographic algorithm that can be used to identify data. AES algorithm is a symmetric ciphertext block that can encrypt and decrypt information quickly. Encryption changes data that can no longer be read called ciphertext; instead, decryption is changing the ciphertext data into the original form that we know as plaintext. The AES algorithm has several key models such as 128, 192, and 256 bits to encrypt and decrypt data on 128-bit message blocks. This study uses a 128-bit key. AES encryption results can be trusted as one of the fast and powerful encryption methods.
