It is shown that the popular RSA public key encryption scheme does not require two primes but that probable primes may be used instead. A method for finding probable primes is given and the security of systems based on probable primes is discussed.
This paper describes a datd mixmg method for encrypting a plaintext block using a block encryption algorithm (such as Elliptic Curve, RSA, etc.) having a block size smaller than that of the plaintext block. The process of encrypting a plaintext block consists of first mixing the plaintext block and
Public-key encryption has been used to encode the key of the encryption process. In the proposed technique, an input image has been encrypted by using the double random-phase-encoding method using extended fractional Fourier transform. The key of the encryption process have been encoded by using the
A (plaintext) message is said to be unconcealable if the encrypted message is the same as the original plaintext message. An analysis of the Williams public-key encryption scheme from the point of view of (un) concealability of messages is presented.
In this paper, we propose a joint encryption scheme (JES) based on discrete logarithms in the plain public key model, in which a sender can easily encrypt messages under the public keys of a group of recipients, so that only by collaborating together can all the recipients recover messages. Neither
