Efficient public key encryption with equality test in the standard model
Theoretical Computer Science, 2019 Public key encryption with equality test (PKEET) is a special kind of public encryption scheme (PKE) that allows a tester to perform equality tests on ciphertexts generated by different public keys as well as the same public key.

Secure and {\sl Practical} Identity-Based Encryption [PDF]
, 2005 In this paper, we present a variant of Waters' Identity-Based Encryption scheme with a much smaller public-key size (only a few kilobytes). We show that this variant is semantically secure against passive adversaries in the standard model.\smallskip In

Security Against Related Randomness Attacks via Reconstructive Extractors [PDF]
, 2015 . This paper revisits related randomness attacks against public key encryption schemes as introduced by Paterson, Schuldt and Sibborn (PKC 2014). We present a general transform achieving security for pub-lic key encryption in the related randomness ...

Public-Key Encryption With Keyword Search via Obfuscation
IEEE Access, 2019 Public-key encryption with keyword search (PEKS) enables users to search on encrypted data, which is applicable to the scenario of sharing data in the cloud storage. In this paper, we focus on how to construct a PEKS scheme via obfuscation.

Cybersecurity-Enhanced Encrypted Control System Using Keyed-Homomorphic Public Key Encryption
IEEE Access, 2023 Encrypted control systems are secure control methods that use the cryptographic properties of a specific homomorphic encryption scheme. This study proposes a cyberattack-detectable encrypted control system and validates its effectiveness using a ...

Anonymity-Preserving Public-Key Encryption: A Constructive Approach [PDF]
, 2013 . A receiver-anonymous channel allows a sender to send a message to a receiver without an adversary learning for whom the message is intended. Wireless broadcast channels naturally provide receiver anonymity, as does multi-casting one message to a ...

On a new fast public key cryptosystem [PDF]
, 2015 This paper presents a new fast public key cryptosystem namely : a key exchange algorithm, a public key encryption algorithm and a digital signature algorithm, based on the difficulty to invert the following function : $F(x) =(a\times x)Mod(2^p)Div(2^q)$
