Cryptography is a process used for sending information in secret way. Goal of this process is to provide protection for information. There are many algorithms exist for this process. For cryptography there are algorithms like RSA, AES, and DES but here we are using only RSA algorithm which is used Encryption and Decryption key. Encryption is one way to ensure good security from unauthorized access in many fields like military communication and medical sciences[1].Image encryption, which basically has two stages: 1) In first stage, each pixel of image is converted to its equivalent eight bit binary number and in that eight bit number, the number of bits, which are equal to the length of password are rotated and then reversed; 2) In second stage, extended hill cipher technique is applied by using involutory matrix, which is generated by same password used in second stage of encryption to make it more secure[3]. |
