Decryption Failure Attacks on Post-Quantum Cryptography. [PDF]
This dissertation discusses mainly new cryptanalytical results related to issues of securely implementing the next generation of asymmetric cryptography, or Public-Key Cryptography (PKC).PKC, as it has been deployed until today, depends heavily on the integer factorization and the discrete logarithm problems.Unfortunately, it has been well-known since ...

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

Multi-Value Plaintext-Checking and Full-Decryption Oracle-Based Attacks on HQC from Offline Templates [PDF]
The Hamming Quasi-Cyclic (HQC) key encapsulation mechanism (KEM), recently selected by NIST for standardization in the Post-Quantum Cryptography (PQC) process, distinguishes itself through its efficiency, robust design based on hard decoding problems in

Exploiting Decryption Failures in Mersenne Number Cryptosystems
Mersenne number schemes are a new strain of potentially quantum-safe cryptosystems that use sparse integer arithmetic modulo a Mersenne prime to encrypt messages. Two Mersenne number based schemes were submitted to the NIST post-quantum standardization process: Ramstake and Mersenne-756839.

On Symmetric Encryption with Distinguishable Decryption Failures [PDF]
We propose to relax the assumption that decryption failures are indistinguishable in security models for symmetric encryption. Our main purpose is to build models that better reflect the reality of cryptographic implementations, and to surface the security issues that arise from doing so.
