ABSTRACT
A Computer Network is an interconnected group of autono mous computing nodes, which use a well defined, mutually agreed set of rules and conventions known as protocols, interact with one -another meaningfully and allow resource sharing preferably in a predictable and controllable manner. Communication has a majo r impact on today‟s business. It is desired to communicate data with high security. Security Attacks compromises the security and hence various Symmetric and Asymmetric cryptographic algorithms have been proposed to achieve the security services such as Authentication, Confidentiality, Integrity, Non-Repudiation and Availability. At present, various types of cryptographic algorithms provide high security to information on controlled networks. These algorithms are required to provide data security and users authenticity. To improve the strength of these security algorithms, a new security protocol for on line transaction can be designed using combination of both symmetric and asymmetric cryptographic techniques. This protocol provides three cryptographic pr imitives such as integrity, confidentiality and authentication. These three primitives can be achieved with the help of Elliptic Curve Cryptography, Dual -RSA algorithm and Message Digest MD5. That is it uses Elliptic Curve Cryptography for encryption, Dual -RSA algorithm for authentication and MD-5 for integrity. This new security protocol has been designed for better security with integrity using a combination of both symmetric and asymmetric cryptographic techniques.
Keywords: Network Security, Elliptic Curve Cryptography, Dual-RSA, Message Digest-5.
