Cryptographic primitives in blockchains
Journal of Network and Computer Applications, 2018 Abstract Blockchain, as one of the crypto-intensive creatures, has become a very hot topic recently. Although many surveys have recently been dedicated to the security and privacy issues of blockchains, there still lacks a systematic examination on the cryptographic primitives in blockchains.

Multipurpose Cryptographic Primitive ARMADILLO3 [PDF]
Smart Card Research and Advanced Application Conference, 2012 This paper describes a new design of the multipurpose cryptographic primitive ARMADILLO3 and analyses its security. The ARMADILLO3 family is oriented on small hardware such as smart cards and RFID chips. The original design ARMADILLO and its variants were analyzed by Sepehrdad et al.

Post-Quantum Cryptographic Hardware Primitives
, 2019 The development and implementation of post-quantum cryptosystems have become a pressing issue in the design of secure computing systems, as general quantum computers have become more feasible in the last two years. In this work, we introduce a set of hardware post-quantum cryptographic primitives (PCPs) consisting of four frequently used security ...

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

Performance analysis of energy efficient improved LEACH protocol in IoT networks
IET Communications, EarlyView., 2022 Abstract The Internet of Things incorporates embedded technologies, wireless sensor networks, control and automation technologies, and wearable devices to enable integrated buildings, enterprises, intelligent homes, and wearable devices. Because sensor nodes have limited power, the energy consumption of the Internet of Things network is critical.

Non-cryptographic primitive for pseudorandom permutation [PDF]
Theoretical Computer Science, 2002 AbstractFour round Feistel permutation (like DES) is super-pseudorandom if each round function is random or a secret universal hash function. A similar result is known for five round MISTY type permutation. It seems that each round function must be at least either random or secret in both cases.In this paper, however, we show that the second round ...

Experimental cheat-sensitive quantum weak coin flipping
Nature 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.
