Improving the efficiency and security of AES algorithm using parallel computation and symbol pattern generation technique

Information security is an important on internet. There are different kinds of information which are business related, academic or user related private data. Illegal access of the information can lead to big losses, so it is important that proper measures should be taken for securing information on internet. Cryptography is a method of storing and sending facts in a particular form so that only those for whom it is intended can read and process it. The word is most often linked with scrambling plain text (ordinary text, sometimes referred to as clear text) into cipher text and then back again to plain text (known as decryption). The most important factors in information security are Security, integrity, non-repudiation, confidentiality, and authentication services. In now days the security of data attracts much attention, especially when these data are stored in memory or send through the communication networks. Many different data encryption methods have been proposed to keep the security of the data. In this paper we propose an improved AES (Advanced Encryption Algorithm) by using the concepts of parallel computation and the quality of encrypted data is further improved by using symbolic pattern generation techniques. The proposed concept is both fast and more secure for encryption, information transmission and decryption.
