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

Breaking the Hidden Irreducible Polynomials Scheme [PDF]
arXiv, 2019 In 2019 G\'omez described a new public key cryptography scheme based on ideas from multivariate public key cryptography using hidden irreducible polynomials. We show that the scheme's design has a flaw which lets an attacker recover the private key directly from the public key.

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 ...

Post-quantum cryptography-driven security framework for cloud computing
Open Computer Science, 2022 Data security in the cloud has been a major issue since the inception and adoption of cloud computing. Various frameworks have been proposed, and yet data breach prevails.

Lattice‐based cryptosystems in standardisation processes: A survey
IET Information Security, 2023 The current widely used public‐key cryptosystems are vulnerable to quantum attacks. To prepare for cybersecurity in the quantum era, some projects have been launched to call for post‐quantum alternatives.

IACR Cryptology ePrint Archive, 2020 . Unlike black-box cryptography, an adversary in a white-box security model has full access to the implementation of the cryptographic algorithm. Thus, white-box implementation of cryptographic algorithms is more practical. Nevertheless, in recent years,
