Precise Undersampling Theorems [PDF]
Proceedings of the IEEE, 2010 Undersampling theorems state that we may gather far fewer samples than the usual sampling theorem while exactly reconstructing the object of interest-provided the object in question obeys a sparsity condition, the samples measure appropriate linear ...

Cryptanalysis of some nonabelian group-based key exchange protocols [PDF]
Journal of Mathematical CryptologyIn the recently emerging field of nonabelian group-based cryptography, a prominently used one-way function is the conjugacy search problem (CSP), and two important classes of platform groups are polycyclic and matrix groups. In this paper, we discuss the

Malware Analysis and Static Call Graph Generation with Radare2
Studia Universitatis Babeș-Bolyai Informatica, 2023 "A powerful feature used in automated malware analysis is the static call graph of the executable file. Elimination of sandbox environment, fast scan, function call patterns beyond instruction level information – all of these motivate the prevalence of ...

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

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.

On density estimation at a fixed point under local differential privacy
, 2021 We consider non-parametric density estimation in the framework of local, both pure and approximate, differential privacy. In contrast to centralized privacy scenarios with a trusted curator, in the local setup anonymization must be guaranteed already on ...

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 ...

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 ...

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 ...
