  • 摘要:Our digital world provides a means to access mammoths of data and services. Such a huge responsibility and task does not come without disadvantages, the most important of which is security and consistency of data and the maintenance of privacy. The science of cryptology has provided us with many means to minimize this disadvantage. This paper attempts to provide another such means to minimize that disadvantage. In this article we present a symmetric key algorithm targeting to improve the problems related to key stream generation. The security of the keystream generation of the proposed algorithm is based on Rijndael forward s � box which is manifest of closure property. The key is a set of matrices along with a tuple of coordinates, noted during the process of encryption. Cache optimization technique used eliminates the disk I/O and ensures maximum memory utilization. The performance of cache, hence the algorithm is dependent on the processor used. This algorithm is especially applicable to networks where fast and secure encryption is and decryption of data is critical.
