In cloud computing, the lightweight, efficient and secure authentication scheme is needed because it is to handle large amounts of data in real-time. Hence, this paper proposes an efficient and lightweight multi-user authentication scheme based on cellular automata (CA) in cloud computing environments. In the proposed scheme, an authentication process is securely performed by a CA-based One-time Password (OTP) authentication which is a randomized evolution. The experiments prove the security of the proposed scheme.
