A modified approach to improve the performance of AES using feistel structure

In encryption algorithm design, apart from the security performance, processing performance and the cost of the implementation are very important trade-off parameters. A most popular and widely adopted symmetric encryption algorithm is the Advanced Encryption Standard (AES). It suffers from the dema...
