Application Application of Data Security with Encryption Method Using AES Algorithm at PLN Rayon Perawang

Abstract

Technology continues to develop, especially in the computer field, so it is very necessary to use computer security properly. Security and confidentiality are important aspects of a message, data or information. Encryption is one method of securing documents that maintains the confidentiality and authenticity of documents, and can increase the security aspects of a document or information. Advanced Encryption Standard (AES) is a symmetric algorithm used for encryption with the aim of protecting sensitive data or information using encryption and decryption techniques with key lengths of 128 bits, 192 bits and 256 bits. The results of the encryption web implementation can lock important files with a 128-Bit key. So that the level of vulnerability to data security breaches is getting lower. Which means that encryption using AES is able to overcome the prevention of vulnerabilities in the collapse of important data.
