Data Security in Wireless Communication using Multiple Keys

Abstract

Encryption is the process to hide the data from plain text to cipher text. The encryption schemes are used to convert the plain text into cipher text. Encryption schemes are also used to transport the keys securely from transmitter to receiver. In this process, overheads are increased; therefore, the generation of keys has been done at the receiver side by the user. The processing of multiple keys from a pool having same data is not an easy task and may generate unreliable keys. The scheme is effective, if the bulk data is present in the pool for the encryption because the generation of multiple keys from the same data is not the effective solution in terms of security point of view. If multiple keys are selected from a small pool, there is always a chance of selection of duplicate key which ruins the encryption process. Comparison of different encryption algorithms has also been done on the basis of data length, key length, type of algorithms and number of iteration. In this work, we modify the key generation process for encryption algorithm and evaluate the processing time in encryption process based upon single and multiple keys. Single password is not efficient for security point of view; therefore, multiple keys have been used. Keys have been generated from the available data. Simulation results shows that the single of 8, 16, 32 and 64 bit key length has less processing time in comparison to multiple keys for 8, 16, 32 and 64 bit key length.
