Multiple-Image Encryption Mechanism Based on Ghost Imaging and Public Key Cryptography
IEEE Photonics Journal, 2019 On the basis of ghost imaging, this paper proposes a multiple-image encryption scheme combining public key cryptography and Hadamard basis pattern. In the encryption system, a plurality of light paths are set, and the Hadamard basis patterns are used for

Group ring cryptography: Cryptography, key exchange, public key [PDF]
Intl. J. of Pure and Appl. Math., 93, no. 6, 897-927, 2014, 2013 General cryptographic schemes are presented where keys can be one-time or ephemeral. Processes for key exchange are derived. Public key cryptographic schemes based on the new systems are easily established. Authentication and signature schemes are implemented.

Certificateless Public Key Cryptography [PDF]
International Conference on the Theory and Application of Cryptology and Information Security, 2003 This paper introduces and makes concrete the concept of certificateless public key cryptography (CL-PKC), a model for the use of public key cryptography which avoids the inherent escrow of identity-based cryptography and yet which does not require certificates to guarantee the authenticity of public keys. The lack of certificates and the presence of an

Revocable identity‐based matchmaking encryption in the standard model
IET Information Security, 2023 Identity‐based Matchmaking Encryption (IB‐ME) is an extension notion of matchmaking encryption (CRYPTO 2019), where a sender and a receiver can specify an access policy for the other party.

Lattice‐based unidirectional Proxy Re‐Encryption and Proxy Re‐Encryption+ schemes
IET Information Security, 2021 The concept of Proxy Re‐Encryption (PRE) was introduced by Blaze, Bleumer and Strauss at Eurocrypt in 1998. In this concept, a semi‐trusted proxy user acquires a re‐encryption key from the delegator.

On Multiple Encryption for Public-Key Cryptography
Cryptography, 2023 Using multiple, individual encryption schemes is a well-established method to increase the overall security of encrypted data. These so-called multiple encryption or hybrid schemes have regained traction in the context of public-key cryptography due to ...
