Development of a symmetric block encryption algorithm based on EM The encryption algorithm includes combining a key with a plaintext using the bitwise addition operation, the developed

For this we will observe the memory utilization and total computational time utilized by the algorithm for the key generation, encryption and decryption.. 1Key Sensitivity: An

Put G in Ciphertext FHE [GSW’13] I Secret key s2Zn, public keyA satisfiesstA⇡0.. Decryption relation is

SSL Record Protocol • Confidentiality — Handshake Protocol defines shared secret key — Used for symmetric encryption • Message Integrity — Handshake Protocol defines shared secret

SSL Record Protocol • Confidentiality — Handshake Protocol defines shared secret key — Used for symmetric encryption • Message Integrity — Handshake Protocol defines shared secret

3: Output the ciphertextc Algorithm 3 RSA Decryption Algorithm Input: A ciphertextc and the private key n, d Output: The plaintext m 1: Calculate m≡cd modn 2: Output the plaintext m

Public Key Encryption Private Key Symmetric Public Key Asymmetric Number of 1 2 keys Protection Must be kept secret One key must be kept secret ; of key the other can be freely

In this paper we will focus in enhancing security level of the encryption-decryption process by introducing a novel method, which uses any digital color image to encode-decode secret
