Information Conservational Security with “Black Hole” Keypad Compression and Scalable One-Time Pad — A Quantum Intelligence Approach to Pre- and Post-Quantum Cryptography
Pre- and Post-Quantum Cryptography Scalable One-Time Pad (S-OTP) Information Conservational Security (ICS)
2019/8/14
Whereas it is widely deemed impossible to overcome the optimality of the one-time pad (OTP) cipher in pre- and post-quantum cryptography, this work shows that the optimality of information theoretic s...
On inverse protocols of Post Quantum Cryptography based on pairs of noncommutative multivariate platforms used in tandem
Multivariate Cryptography Noncommutative Cryptography stable transformation groups and semigroups
2019/8/6
Non-commutative cryptography studies cryptographic primitives and systems which are based on algebraic structures like groups, semigroups and noncommutative rings. We con-tinue to investigate inverse ...
General Linear Group Action on Tensors: A Candidate for Post-Quantum Cryptography
Group actions isomorphism problems signature schemes
2019/6/12
Starting from the one-way group action framework of Brassard and Yung (Crypto '90), we revisit building cryptography based on group actions. Several previous candidates for one-way group actions no lo...
NIST Post-Quantum Cryptography- A Hardware Evaluation Study
Post-Quantum Cryptography Hardware Implementation
2019/1/26
Experts forecast that quantum computers can break classical cryptographic algorithms. Scientists are developing post quantum cryptographic (PQC) algorithms, that are invulnerable to quantum computer a...
A publicly verifiable quantum signature scheme based on asymmetric quantum cryptography
Undeniable quantum signature scheme Impersonation attack Quantum asymmetric cryptography
2019/1/16
In 2018, Shi et al. 's showed that Kaushik et al.'s quantum signature scheme is defective. It suffers from the forgery attack. They further proposed an improvement, trying to avoid the attack. However...
Post-quantum cryptography---dealing with the fallout of physics success
public-key cryptography post-quantum cryptography
2017/4/17
Post-quantum cryptography is cryptography under the assumption that the attacker has a large quantum computer; post-quantum cryptosystems strive to remain secure even in this scenario. This relatively...

Signal security aims to prevent the adversary from copying communication
signals—so it is with quantum cryptography. Information security focuses on
preventing the adversary from knowing plaintext o...
Shor’s quantum factoring algorithm and a few other efficient quantum algorithms break many classical
crypto-systems. In response, people proposed post-quantum cryptography based on computational
pro...
