A Survey on Implementation and Analysis of Image base key generation and Authentication for Cyber Security

Cryptography is a progressive technology that Uses key for encryption with plain text . The use of image For the purposes of has become more popular in now a days , but The use of images in cryptography is a new area of research. This paper proposes the method of image base key generation in cryptographic. Cryptography is basically protecting the data or information while the communication takes place between different systems and party. The integrity and confidentiality of the data in communication is important which depends partially on algorithm and partially on key. The key length in cryptography is limited due to human memorize ability. The main objective of this paper is to achieve the security of the communication by encrypting the original information with the key generated by using an images in a session manner. According to the selection of session type a key is generated which is used for encryption and decryption of the messages which is further transmitted and received between two parties at different station. The key length changes in every session according to the session type. This is a reliable and flexible way to generate the key which is used for secure the information which get transferred on the networks and it is easy to implement. This method try to ensures the prevention of guesses or breaking the key and provides a more secure way for information encryption.
