E-Commerce Security using New Public Key Algorithm based on Block Cipher

Now a day’s, E-Commerce business is very much needed for the individuals and concern. On-line business increases information sharing, a concern regarding the exchange of money securely and conveniently over the internet increases. Therefore, security is a necessity in an ecommerce transaction. The requirements for securing ecommerce transaction 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 channels. The efficiency of the security methods are measured and such efficiency increases as we combined more security methods with each other. A new method of security is suggested which is a based on block cipher algorithm. Block cipher algorithm used until symmetric algorithm, this is the first time we are applying in e-commerce business as a Public Key Infrastructures (PKI). The concept of this new e-commerce securing algorithm is based on modular 37. KeywordsE-commerce, Trusted Third Party (TTP), Private Key and symmetric key, Public key or Asymmetric key
