Cryptography in Digital Payments: Ensuring Secure and Trustworthy Financial Transactions

Abstract

Since the mobile systems are growing quickly, the e-commerce will change gently to m-commerce. As a result, mobile security will become the one of the most important part of mobile system and will become the hottest area facing the mobile payment due to mobile networks directness. However, the appropriate encryption scheme for mobile communication must have small amount of data calculating and quick operation as of its inherent restrictions of small quantity and low calculating ability. The objectives of this paper are to look at mobile payment and its security. Also, to explain elliptic curve with public key encryption, authentication of security wireless milieu. Compare with the RSA scheme, an elliptic curve has shorter key size, smaller signature length, low calculating, fast operations and high security working.
