Sharing the LUOV: Threshold Post-Quantum Signatures
cryptographic protocols linear secret shared schemes
2019/9/19
We examine all of the signature submissions to Round-2 of the NIST PQC ``competition'' in the context of whether one can transform them into threshold signature schemes in a relatively straight forwar...
Post-Quantum Variants of ISO/IEC Standards: Compact Chosen Ciphertext Secure Key Encapsulation Mechanism from Isogenies
Post-quantum cryptosystems Isogeny-based cryptosystems CSIDH
2019/9/17
ISO/IEC standardizes several chosen ciphertext-secure key encapsulation mechanism (KEM) schemes in ISO/IEC 18033-2. However, all ISO/IEC KEM schemes are not quantum resilient. In this paper, we introd...
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 ...
Prototyping post-quantum and hybrid key exchange and authentication in TLS and SSH
post-quantum cryptography TLS SSH
2019/7/25
Once algorithms for quantum-resistant key exchange and digital signature schemes are selected by standards bodies, adoption of post-quantum cryptography will depend on progress in integrating those al...
SPQCop: Side-channel protected Post-Quantum Cryptoprocessor
cryptography post-quantum key-exchange cryptoprocessor
2019/7/8
The past few decades have seen significant progress in practically realizable quantum technologies. It is well known since the work of Peter Shor that large scale quantum computers will threaten the s...
Post-Quantum UC-Secure Oblivious Transfer in the Standard Model with Adaptive Corruptions
Smooth Projective Hash Functions Oblivious Transfer
2019/6/19
Since the seminal result of Kilian, Oblivious Transfer has proven to be a fundamental primitive in cryptography. In such a scheme, a user is able to gain access to an element owned by a server, withou...
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...
Subliminal channels in post-quantum digital signature schemes
Subliminal channels post-quantum digital signatures
2019/5/29
We analyze the digital signatures schemes submitted to NIST's Post-Quantum Cryptography Standardization Project in search for subliminal channels.
Post-quantum cryptography has gathered significant attention in recent times due to the NIST call for standardization of quantum resistant public key algorithms. In that context, supersingular isogeny...
With this work, we intend on demonstrating the need for improvements to the currently standardized AES family of cryptosystems, and provide a solution that meets the requirements of long-term security...
Many post-quantum cryptosystems which have been proposed in the National Institute of Standards and Technology (NIST) standardization process follow the same meta-algorithm, but in different algebras ...
With the rapid development of quantum technologies, quantum-safe cryptography has found significant attention. Hash-based signature schemes have been in particular of interest because of (i) the impor...
Post-Quantum Provably-Secure Authentication and MAC from Mersenne Primes
secret-key cryptography MERS
2019/4/23
This paper presents a novel, yet efficient secret-key authentication and MAC, which provide post-quantum security promise, whose security is reduced to the quantum-safe conjectured hardness of Mersenn...
Timing attacks on Error Correcting Codes in Post-Quantum Secure Schemes
Post-Quantum Cryptography Decryption Failures Side-Channel Attacks
2019/3/20
While error correcting codes (ECC) have the potential to significantly reduce the failure probability of post-quantum schemes, they add an extra ECC decoding step to the algorithm. As this additional ...
