WebSep 25, 2012 · A new cipher combining the characteristics of two ciphers namely AES and Rc4 is generated which is more secure than the original cipher and resistant against most attacks. This paper aims at developing a new hybrid cipher by combining the characteristics of two ciphers namely AES(Advanced Encryption Standard) and Rc4(also known as … Webconsumption due to encryption algorithms. Designing energy efficient security protocols first requires an understanding of and data related to the energy consumption of common encryption schemes. In this paper, we provide the results of experiments with AES and RC4, two symmetric key algorithms that are commonly suggested or used in WLANs.
