Message Authentication (MAC) Algorithm For The VMPC-R (RC4-like) Stream Cipher
Abstract
We propose an authenticated encryption scheme for the VMPC-R stream cipher. VMPC-R is an RC4-like algorithm proposed in 2013. It was created in a challenge to find a bias-free cipher within the RC4 design scope and to the best of our knowledge no security weakness in it has been published to date. The contribution of this paper is an algorithm to compute Message Authentication Codes (MACs) along with VMPC-R encryption. We also propose a simple method of transforming the MAC computation algorithm into a hash function.
