Novel Hybrid Public/Private Key Cryptography Based on Perfect Gaussian Integer Sequences [PDF]

IEEE Access, 2021
This paper proposes a novel hybrid public/private key cryptography scheme based on perfect Gaussian integer sequences (PGISs) of period $N=pq$ . First, a review study of construction degree-4 PGIS is addressed.

A Complex Matrix Private Key to Enhance the Security Level of Image Cryptography

Symmetry, 2022
Standard methods used in the encryption and decryption process are implemented to protect confidential data. These methods require many arithmetic and logical operations that negatively affect the performance of the encryption process. In addition, they use private keys of a specific length, in addition to the fixed length of the data block used in ...

On the Impossibility of Private Key Cryptography with Weakly Random Keys [PDF]

Annual International Cryptology Conference, 2007
The properties of weak sources of randomness have been investigated in many contexts and using several models of weakly random behaviour. For two such models, developed by Santha and Vazirani, and Chor and Goldreich, it is known that the output from one such source cannot be "compressed" to produce nearly random bits.

Circulant Rainbow: A New Rainbow Variant With Shorter Private Key and Faster Signature Generation

IEEE Access, 2017
Rainbow is one of the most important signature schemes in multivariate public key cryptography. It enjoys a strong security guarantee and is a promising signature scheme in Post-Quantum Cryptography. However, it suffers from large key size. In this paper,

A Secure Visual Cryptography Scheme Using Private Key with Invariant Share Sizes

Journal of Software Engineering and Applications, 2017
Visual cryptography (VC) is one of the best techniques used to secure information. It uses the human vision to decrypt the encrypted images without any cryptographic computations. The basic concept of visual cryptography is splitting the secret image into shares such that when the shares are stacked, the secret image is revealed.
