The mF mode of authenticated encryption with associated data
Journal of Mathematical Cryptology, 2022 In recent years, the demand for lightweight cryptographic protocols has grown immensely. To fulfill this necessity, the National Institute of Standards and Technology (NIST) has initiated a standardization process for lightweight cryptographic encryption.

Accountable multi-authority attribute-based data access control in smart grids
Journal of King Saud University: Computer and Information Sciences, 2023 The developments of AI, information security and network technology have improved the security, efficiency of the smart grid system. However real-time data and consume data sharing make privacy leakage, malicious entities and users be uncontrollable ...

A construction of encryption protocols over some semidirect products
Journal of Mathematical Cryptology, 2023 In CANDARW ’18, Isobe et al. proposed a secure encryption protocol on non-abelian groups based on the Anshel–Anshel–Goldfeld key exchange protocol. There have remained two weak points on the protocol: one is that the protocol is indistinguishable against

Provable security against generic attacks on stream ciphers
Journal of Mathematical Cryptology, 2023 Recent lightweight hardware-based stream cipher designs keep an external non-volatile internal state that is not part of the cipher’s hardware module. The purpose of these so-called small-state ciphers is to keep the size of the hardware and the power ...

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.

Towards a Ring Analogue of the Leftover Hash Lemma
Journal of Mathematical Cryptology, 2020 The leftover hash lemma (LHL) is used in the analysis of various lattice-based cryptosystems, such as the Regev and Dual-Regev encryption schemes as well as their leakage-resilient counterparts. The LHL does not hold in the ring setting, when the ring is

Efficiently Processing Complex-Valued Data in Homomorphic Encryption
Journal of Mathematical Cryptology, 2020 We introduce a new homomorphic encryption scheme that is natively capable of computing with complex numbers. This is done by generalizing recent work of Chen, Laine, Player and Xia, who modified the Fan–Vercauteren scheme by replacing the integral ...

Another look at normal approximations in cryptanalysis
Journal of Mathematical Cryptology, 2016 Statistical analysis of attacks on symmetric ciphers often requires assuming the normal behaviour of a test statistic. Typically such an assumption is made in an asymptotic sense.

(In)Security of Ring-LWE Under Partial Key Exposure
Journal of Mathematical Cryptology, 2020 We initiate the study of partial key exposure in Ring-LWE (RLWE)-based cryptosystems. Specifically, we (1) Introduce the search and decision Leaky R-LWE assumptions (Leaky R-SLWE, Leaky R-DLWE), to formalize the hardness of search/decision RLWE under ...

Security analysis of Modified Rivest Scheme
Journal of Mathematical Cryptology, 2014 The Modified Rivest Scheme (MRS) is an additive homomorphic scheme recently used in many applications which demands third party processing of encrypted data. The present study carries out a comprehensive security analysis of MRS.
