A Novel Hybrid Security Model for E-Commerce Channel

The prime requirements for any e-commerce or m-commerce transactions are privacy, authentication, integrity maintenance and non-repudiation. These are the crucial and significant issues in recent times for trade which are transacted over the internet through e-commerce and m-commerce channels. To overcome these issues, various security mechanisms related to symmetric and asymmetric type have been designed. Digital Envelope is one of the practices to attain the prime requirements in e-commerce channels. In this paper, we suggest a software implementation of a digital envelope for a secure e-commerce channel that combines the hashing algorithm of MD5, the symmetric key algorithm of AES and the asymmetric key algorithm of Hyperelliptic Curve Cryptography (HECC). The result illustrates that HECC is the best alternative asymmetric key technique rather than ECC and RSA in the digital envelope hybrid cryptosystem.
