The growing importance of information security over recent years has prompted development of secure encryption algorithms. Most of the traditional algorithms such as AES and DES are computationally intensive. Hence, in this paper we propose a simple but secure symmetric key encryption algorithm. The image encryption approach makes use of two pseudorandom number generators to encrypt images. Middle...
Encryption is a process of hiding significant data so as to prevent unauthorized access and ensure confidentiality of data. It is widely used to transmit data across networks ensuring secure communication. This paper aims at improving the security and efficiency of image encryption by using a highly efficient shuffle based encryption algorithm and an equivalent decryption algorithm based on random...
