New Cryptographic Primitive: Definition, Model and Construction of Ratched Key Exchange [PDF]

open access: yesJisuanji kexue, 2022
In the application of traditional cryptography,people always assume that the endpoints are secure and the adversary is on the communication channel.However,the prevalence of malware and system vulnerabilities makes endpoint compromise a se-rious and ...

Linear Complexity of Hidden Weighted Bit Functions [PDF]

open access: yesJisuanji kexue yu tansuo, 2023
Boolean functions are crucial primitive in block cipher and are also used to design pseudorandom sequences. They play a crucial role in the design of symmetric cryptography and its analysis, and the study on the cryptographic properties of Boolean ...

Towards Lightweight Provable Data Possession for Cloud Storage Using Indistinguishability Obfuscation

open access: yesIEEE Access, 2022
Cloud Computing has proved to be a boon for many individuals and organizations who cannot afford infrastructure and maintenance cost of resources. But the untrusted nature of Cloud Server (CS) brings many challenges related to security and trust.

Experimental cheat-sensitive quantum weak coin flipping

open access: yesNature Communications, 2023
Quantum-enhanced versions of weak coin flipping (a cryptographic primitive where two mistrustful parties agree on a random bit while favouring opposite outcomes) have been proposed in the past but never realised.

Feebly secure cryptographic primitives [PDF]

open access: yesJournal of Mathematical Sciences, 2012
In 1992, A. Hiltgen provided first construction of provably (slightly) secure cryptographic primitives, namely, feebly one-way functions. These functions are provably harder to invert than to compute, but the complexity (viewed as the circuit complexity over circuits with arbitrary binary gates) is amplified only by a constant factor (in Hiltgen’s ...
