摘要：Information security algorithms are widely used in the recent times to protect data and messages over internet. Elliptic Curve Cryptography (ECC) is one of the most efficient techniques that are used for this issue, because it is difficult for the adversary to solve the elliptic curve discrete logarithm problem to know the secret key that is used in encryption and decryption processes. A new efficient method has been proposed in this paper to improve the Menezes-Vanstone Elliptic Curve Cryptography (MVECC). This modification reduces the running time needed for encryption and decryption processes compared with the original method and another two methods. In the modified method, only addition and subtraction operations are used, and no inversion or multiplication operations because it consumes a long time comparing with addition and subtraction, and this makes the proposed algorithm faster in computations and running time than the original and other methods. Moreover, the modified method uses the hexadecimal ASCII value to encode each character in the message before encryption, which makes the algorithm more secure and complicated to resist the adversaries.
