A NEW SYMMETRICAL ENCRYPTION ALGORITHM WITH HIGH SECURITYAND DATA RATE FOR WLAN
Journal Title: International Journal of Engineering, Science and Mathematics - Year 2012, Vol 2, Issue 4
Abstract
The hacking is the greatest problem in the wireless local area network (WLAN). Many algorithms like DES, 3DES, AES,CAST, UMARAM and RC6 have been used to prevent the outside attacks to eavesdrop or prevent the data to be transferred to the end-user correctly. The authentication protocols have been used for authentication and key-exchange processes. A new symmetrical encryption algorithm is proposed in this paper to prevent the outside attacks to obtain any information from any data-exchange in Wireless Local Area Network(WLAN). The new symmetrical algorithm avoids the key exchange between users and reduces the time taken for the encryption, decryption, and authentication processes. It operates at a data rate higher than DES, 3DES, AES, UMARAM and RC6 algorithms. It is applied on a text file and an image as an application. The encryption becomes more secure and high data rate than DES,3DES,AES,CAST,UMARAM and RC6. This new algorithm is designed and implemented by g.ramesh et al. in the year 2010 to prevent the outside attacks to obtain any information from any dataexchange in Wireless Local Area Network. A comparison has been conducted for those encryption algorithms at different settings for each algorithm such as different sizes of data blocks, different data types, battery power consumption, different key size and finally encryption/decryption speed. Experimental results are given to demonstrate the effectiveness of each algorithm.
