An Energy Efficient Authentication Scheme using Chebyshev Chaotic Map for Smart Grid Environment
As one of the important applications of Smart grid, charging between electric
vehicles has attracted much attention. However, authentication between vehicle
users and an aggregator may be vulnerable to various attacks due to the usage
of wireless communications. In order to reduce the computational costs yet
preserve required security, the Chebyshev chaotic map based authentication
schemes are proposed. However, the security requirements of Chebyshev
polynomials bring a new challenge to the design of authentication schemes based
on Chebyshev chaotic maps. To solve this issue, we propose a practical
Chebyshev polynomial algorithm by using a binary exponentiation algorithm based
on square matrix to achieve secure and efficient Chebyshev polynomial
computation. We further apply the proposed algorithm to construct an
energy-efficient authentication and key agreement scheme for smart grid
environments. Compared with state-of-the-art schemes, the proposed
authentication scheme effectively reduces the computational costs and
communication costs by adopting the proposed Chebyshev polynomial algorithm.
Furthermore, the ProVerif tool is employed to analyze the security of the
proposed authentication scheme. Our experimental results justified that our
proposed authentication scheme can outperform state-of-the-art schemes in terms
of the computational overhead while achieving privacy protection.Comment: 10 pages, 7 figure
