On the Construction of a Post-Quantum Blockchain
2021 IEEE Conference on Dependable and Secure Computing (DSC), 2021Consensus and transaction are the main parts in a blockchain system. However, most cryptographic protocols used in these parts of current blockchains are vulnerable to rapid development of quantum computers. Besides, traditional proof of work (PoW) based consensus protocols such as Bitcoin can not supply memory mining.

Post-Quantum Crystography: A combination of Post-Quantum Cryptography and Steganography
8th International Conference for Internet Technology and Secured Transactions (ICITST-2013), 2013Crystography is the combination of Cryptography and Steganography for enhancing the security of communications over enterprise networks. Most existing Crystographic systems are based on Public key Cryptographic schemes like RSA and Elliptic Curve Cryptography (ECC), whose security depends on the difficulty of solving Integer Factorisation Problem (IFP)

This paper proposes RSA parameters for which (1) key generation, encryption, decryption, signing, and verification are feasible on today’s computers while (2) all known attacks are infeasible, even assuming highly scalable quantum computers. As part of the performance analysis, this paper introduces a new algorithm to generate a batch of primes.

A secure boot protocol is fundamental to ensuring the integrity of the trusted computing base of a secure system. The use of digital signature algorithms (DSAs) based on traditional asymmetric cryptography, particularly for secure boot, leaves such systems vulnerable to the threat of quantum computers.

Blockchained Post-Quantum Signatures
2018 IEEE International Conference on Internet of Things (iThings) and IEEE Green Computing and Communications (GreenCom) and IEEE Cyber, Physical and Social Computing (CPSCom) and IEEE Smart Data (SmartData), 2018Inspired by the blockchain architecture and existing Merkle tree based signature schemes, we propose BPQS, an extensible post-quantum (PQ) resistant digital signature scheme best suited to blockchain and distributed ledger technologies (DLTs). One of the unique characteristics of the protocol is that it can take advantage of application-specific chain ...

Anonymous Post-Quantum Cryptocash
2018In this paper, we construct an anonymous and decentralized cryptocash system which is potentially secure against quantum computers. In order to achieve that, a linkable ring signature based on ideal lattices is proposed. The size of a signature in our scheme is \(O(\log N)\), where N is the cardinality of the ring.

Post-quantum signatures for today
2009Digital signatures are essential for the security of computer networks such as the Internet. For example, digital signatures are widely used to ensure the authenticity and integrity of updates for operating systems and other software applications. The security of the few practically used signature schemes is threatened by quantum computers.

Post-Quantum Cryptographic Primitives
2020The necessity of cyber-security is becoming apparent as we grow increasingly dependent on technology in our daily lives. Cybersecurity allows us to protect our digital information that is stored and transferred via the Internet. Because of this growing dependence, this research project endeavours to design, construct and evaluate new post-quantum ...

Benchmarking Post-quantum Cryptography in TLS
2020Post-quantum cryptographic primitives have a range of trade-offs compared to traditional public key algorithms, either having slower computation or larger public keys and ciphertexts/signatures, or both. While the performance of these algorithms in isolation is easy to measure and has been a focus of optimization techniques, performance in realistic ...

Revisiting Post-quantum Fiat-Shamir
2019The Fiat-Shamir transformation is a useful approach to building non-interactive arguments (of knowledge) in the random oracle model. Unfortunately, existing proof techniques are incapable of proving the security of Fiat-Shamir in the quantum setting.
