Abstract
In the age of intensive data exchanges, security of data poses a major challenge to the existing communication arrangement. In this context the evolution and evaluation of new encryption system is inextricably linked to the process of realizing ever increasing network security needs. Recently a Generalized Key Scheme in a Block Cipher Algorithm (GKSBC) is found to be robust in cryptanalysis and the result of key sensitivity analysis was found satisfactory. This study compares GKSBC with the class of block cipher algorithms viz., RC6, AES and Blowfish, and presents a performance evaluation. To assess the encryption quality two measures viz., Encryption Quality measure and Correlation analysis is applied. Thorough experimental tests with detailed analysis showed the high quality and comparative efficiency of GKSBC algorithm. Keywords: symmetric, generalized, throughput, encryption, correlation
