Abstract: The work presents a Convertible Multi-Authenticated Encryption (CMAE) scheme based on the Elliptic Curve Discrete Logarithm Problem (ECDLP). The proposed scheme intended to develop the CMAE scheme to improve performance as compared to the other existing schemes. Most CMAE schemes are very high in computational overhead and memory usage problem. This scheme desired to reduce time-consuming problem by using Elliptic Curve Cryptography (ECC). In addition, the proposed scheme provides good resistance to the chosen plain-text attacks and is proven to be secure. As for efficiency, the computation cost of the proposed scheme is smaller than the existing schemes, such as Lu et al.'s scheme.

Keywords: multi-authenticated encryption; elliptic curve discrete logarithm problem; chosen plain-text attacks; elliptic curve cryptography; ECC; verification; security.
