摘要：Information and computer security become a key issue these days. This is due to rapid developments in data communications and computer technologies. Hence, there is a serious need for a secure transmission of both data and information between senders and receivers. Since there is no fully secured communication system for Web-based systems, communication systems rely heavily on complex and difficult cipher systems. Cipher systems usually consist of two main parts; Encryption and Decryption to hide and secure both transmitted data and information on long trunks. In addition, storing both important and sensitive data and information requires securing them from intruders, which can be handled by encrypting them. This paper studies one of the most important and widely used secret key encryption/decryption algorithms, namely the Advanced Encryption Standard (AES). The implementation of the AES algorithm involves complex computational steps that have made the implementation of these steps slow and time consuming. Using state of the art of multi-core architecture, we propose a pipelined implementation of the AES algorithm to reduce both computation complexity and elapsed computation time. Our contribution, the proposed AES implementation does not require dedicated equipment, it works with any kind of computers that are available to the public, such as Intel-based computers. A comparison of CPU performance is performed on both pipelined and sequential implementations on different file sizes. We have found that our pipelined implementation outperforms the sequential one, without the use of any special equipment. What distinguishes our work from the rest of the work done by several researchers is that the proposed AES implementation is designed for multi-core computers that do not have expensive equipment such as GPU or FPGA, such devices are widely available.
