A failure in decryption process for bivariate polynomial reconstruction problem cryptosystem

Heliyon
In 1999, the Polynomial Reconstruction Problem (PRP) was put forward as a new hard mathematics problem. A univariate PRP scheme by Augot and Finiasz was introduced at Eurocrypt in 2003, and this cryptosystem was fully cryptanalyzed in 2004.

LEDAcrypt: QC-LDPC Code-Based Cryptosystems with Bounded Decryption Failure Rate [PDF]

Lecture Notes in Computer Science, 2019
We consider the QC-LDPC code-based cryptosystems named LEDAcrypt, which are under consideration by NIST for the second round of the post-quantum cryptography standardization initiative. LEDAcrypt is the result of the merger of the key encapsulation mechanism LEDAkem and the public-key cryptosystem LEDApkc, which were submitted to the first round of the

Decryption Failure Attacks on IND-CCA Secure Lattice-Based Schemes

Lecture Notes in Computer Science, 2019
In this paper we investigate the impact of decryption failures on the chosen-ciphertext security of lattice-based primitives. We discuss a generic framework for secret key recovery based on decryption failures and present an attack on the NIST Post-Quantum Proposal ss-ntru-pke.

Enhanced NTRU cryptosystem eliminating decryption failures

Journal of Systems Engineering and Electronics, 2006
Summary: An enhaned NTRU cryptosystem eliminating decryption failures is proposed without using padding schemes and can resist the oracle model and chosen-ciphertext attacks. Because lattice reduction is the main threat to lattice-based cryptosystems, lattice reduction algorithms are analyzed to evaluate the security of this scheme.

On Accuracy of Testing Decryption Failure Rate for Encryption Schemes under the LWE Assumption

IET Information Security
Lattice-based encryption schemes are significant cryptographic primitives to defend information security against quantum menace, and the decryption failure rate is related to both theoretical and realistic security.

Empirical Headroom Diagnostics for ML-KEM Deployments: Reproducible Assessment of Decryption Failure Risk Under FIPS 203

IEEE Access
Formal correctness proofs, analytical tail bounds, and empirical failure studies provide strong guarantees for the Module-Lattice-Based Key-Encapsulation Mechanism (ML–KEM).

Probabilistic modeling of decryption-failure bounds in CRYSTALS-Kyber under the post-quantum threat model

Machine Learning: Science and Technology
We present a probabilistic modeling framework for quantifying decryption-failure probability (DFP) in CRYSTALS–Kyber , the lattice-based key encapsulation mechanism standardized by National Institute of Standards and Technology as module-lattice-based ...

Enhancing security in instant messaging systems with a hybrid SM2, SM3, and SM4 encryption framework. [PDF]

PLoS ONE
With the rapid integration of instant messaging systems (IMS) into critical domains such as finance, public services, and enterprise operations, ensuring the confidentiality, integrity, and availability of communication data has become a pressing concern.

Distributed Attribute-Based Encryption Scheme Based on Fog Nodes [PDF]

Jisuanji gongcheng, 2021
The existing cloud storage schemes have multiple limitations, including the general division of user rights to access data, fine-grained control access permissions, and single point of failure in single authority.This paper proposes a distributed ...

HybridPKE: A forward-secure non-interactive quantum-safe hybrid key exchange scheme

Engineering Science and Technology, an International Journal, 2022
The schemes submitted to NIST call for standardization of post-quantum cryptography have some common drawbacks in terms of decryption failure probability, scalability, and switching issues from pre-quantum to post- quantum cryptography. In this paper, we
