Time Performance Analysis of RSA and Elgamal Public Key Cryptosystems ijtsrd
Computer and network security system are needed to protect data during their transmissions and to guarantee that data are authentic. Cryptography is useful not only for proving data to be secure but also for ensuring that data have not altered. So, it is needed to implement the public key cryptosystem in computer and network security […]
Comparative Study of Security Algorithms IJTSRD
At present, through internet lots of confidential data is send across the world and though it is confidential it needs protection from unauthorized person who will try to read that data so to protect the data from unauthorized person security algorithms are used through which the original data can be able to convert into encrypted […]
AES Algorithm: Encryption and Decryption IJTSRD
Advanced Encryption Standard (AES) algorithm is one of the most common and widely used symmetric block cipher algorithm. This algorithm has its own particular structure to encrypt and decrypt sensitive data and is applied in hardware and software, all over the world. It is extremely difficult for hackers to get the real data when encrypting […]
Image Realization Steganography by Secure Key Transmission IJTSRD
This work proposes a novel scheme for separable reversible data hiding in encrypted images. In the first phase, a content owner encrypts the original uncompressed image using an encryption key. Then, a data-hider may compress the least significant bits of the encrypted image using a data-hiding key to create a sparse space to accommodate some […]
