Using RC4 and Whirlpool for the Encryption and Validation of Data in IoT

Abstract

We propose a combined cryptographic algorithm involving the RC4 and Whirlpool protocols for the encryption and validation of data in Internet-of-Things (IoT). The RC4 is a symmetric cryptographic algorithm or cipher for encrypting and decrypting the data; and the Whirlpool is a Hash function for ensuring correctness of data (data integrity and authentication) as data is communicated among nodes within the IoT ecosystem. The proposed algorithm is strong, easy to implement and above all, has a faster throughput. Although, it takes less time to implement, it has several advantages over other symmetric ciphers. The whirlpool hash is used to augment the strength of the RC4 to help it stand current cyber-attacks that the cipher suffers from.
