A novel encryption solution for real time applications

Cryptography technology is one of the most important security methods that guarantee the security requirement such as confidentiality, integrity and non-repudiation. The importance of the cryptography is very clear in transmitting a sensitive date through an open network such as Internet. Some of the current algorithms are not fully applicable with the Real Time Applications due to its sensitivity of time. In this paper, an encryption algorithm is suggested to deal with RTA´s that is supposed to spend less time compared to the AES and Blowfish. The first of the proposed solution is that the key is regenerated with a different value in each single round from its sixth different rounds. The use of XOR operation is appropriate with RTA with reference to its lightweight and speed.
