Advanced Encryption Standard to Prevent Intruders in Email through Cloud Environment

The Advanced Encryption Standard (AES) algorithm is currently one of the most widely used symmetric block ciphers. Its unique structure enables it to be incorporated into various tools and software globally, providing a high level of security. As a result, considerable care must be taken when implementing it. There hasn't been any proof to far that this algorithm can be broken. The AES algorithm provides three different key sizes, namely 128, 192, and 256 bits, all of which use a block size of 128 bits. This research study will provide a detailed explanation of the AES algorithm, including instructions on how to encrypt and decrypt sensitive data using this method. To successfully retrieve the data encrypted using AES, several critical aspects of the algorithm should be considered.
