摘要：Many ways to encrypt data have been innovated as the time moving, starting with simple ideas like changing positions of letters throughout to very high and complicated mathematical calculations to provide the element of security to our important data. Advanced Encryption Standard (AES) is one of the famous algorithms ¨C specially Rijndael Algorithm- although there are other algorithms have been preferred upon rijndael algorithm in the field of security, rijndael algorithm has been selected as a symmetric cipher standard algorithm because of its high performance. So In this thesis there is an attempt to Enhance the security of rijndael algorithm by adding another key in both encryption and decryption operations to increase the strength of security and keep the performance close to traditional algorithm as much as possible using java programming language to implement the algorithm and monitoring the performance by calculating the execution time of encryption, decryption and generating key(s) in different numbers of sessions which had been opened between sender and receiver.
