An Approach for Node Authentication Using Zero-Knowledge Proof

Abstract

Authentication is primary process by which you can verify that someone is legitimate user or not. The identification of an entity or person is based on the username and password provided to that entity. In security systems, authentication is playing an important role by which it provides access to the system to an entity based on their identity. Authentication only ensures that the entity who is claims to be, but do not passes any information about the access rights of the entity. The zero- knowledge protocol used to provide data security and zero-knowledge transfer during authentication. The proposed model for node authentication using zero - knowledge proof for secure login is much faster than existing model in terms of execution time, CPU usage, time complexity and performance. It also provides security features likes confidentiality, integrity, authentication and non-repudiation.
