Public-Key Cryptography Based on Tropical Circular Matrices

Applied Sciences, 2022
Some public-key cryptosystems based on the tropical semiring have been proposed in recent years because of their increased efficiency, since the multiplication is actually an ordinary addition of numbers and there is no ordinary multiplication of numbers

New approach to practical leakage-resilient public-key cryptography

Journal of Mathematical Cryptology, 2020
We present a new approach to construct several leakage-resilient cryptographic primitives, including leakage-resilient public-key encryption (PKE) schemes, authenticated key exchange (AKE) protocols and low-latency key exchange (LLKE) protocols.

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

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.
