Software/Hardware Codesign of the Post Quantum Cryptography Algorithm NTRUEncrypt Using High-Level Synthesis and Register-Transfer Level Design Methodologies

When quantum computers become scalable and reliable, they are likely to break all public-key cryptography standards, such as RSA and Elliptic Curve Cryptography. The projected threat of quantum computers has led the U.S. National Institute of …

DAGS: Key encapsulation using dyadic GS codes

Code-based cryptography is one of the main areas of interest for NIST’s Post-Quantum Cryptography Standardization call. In this paper, we introduce DAGS, a Key Encapsulation Mechanism (KEM) based on quasi-dyadic generalized Srivastava codes. The scheme is proved to be IND-CCA secure in both random oracle model and quantum random oracle model. We believe that DAGS will offer competitive performance, especially when compared with other existing code-based schemes, and represent a valid candidate for post-quantum standardization.

DAGS: Reloaded Revisiting Dyadic Key Encapsulation

In this paper we revisit some of the main aspects of the DAGS Key Encapsulation Mechanism, one of the code-based candidates to NIST’s standardization call for the key exchange/encryption functionalities. In particular, we modify the algorithms for …
