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. We show that circular convolution over PGISs is a trapdoor one-way permutation function that enables simultaneous cipher encryption and ...

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.

A biometrics-generated private/public key cryptography for a blockchain-based e-voting system
Egyptian Informatics JournalVoting aims to provide the best decision or select the most selected option for the largest group of voters. Malicious parties gaining access, and otherwise tampering with election results, or the votes make this effort counterproductive. To alleviate this, this study examined the introduction of blockchain.

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]
, 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.

Function Codes For Protection Of Key In Private Key Cryptography
, 2017 In order to check the applicability and correctness of any designed algorithm, it is must to write a code on any suitable platform that successfully implements the logic. The present work is actually an extension to what we have done in our previous works where we have tried to devise an algorithm which is based on the most popular and largely applied ...

New Approach for Encryption Private key for Sender by using Hill Cipher with GGH Cryptography
, 2021 One of the important issues in the encryption used in networks is the Hill encryption method, but it is not practical in economic matters or the Internet, It is very difficult to send the private key to the receive in order to decrypt the message, due to the high exposure to third-party attacks, and therefore it is recommended that the private key must

Privately Generated Key Pairs for Post Quantum Cryptography in a Distributed Network
Applied SciencesIn the proposed protocol, a trusted entity interacts with the terminal device of each user to verify the legitimacy of the public keys without having access to the private keys that are generated and kept totally secret by the user. The protocol introduces challenge–response–pair mechanisms enabling the generation, distribution, and verification of ...
