DAGS: Key Encapsulation using Dyadic GS Codes

This paper presents DAGS, a key encapsulation mechanism (KEM) based on dyadic Goppa codes, contributing to the landscape of code-based post-quantum cryptographic proposals.

The DAGS scheme:

• Is efficient and compact due to the dyadic structure
• Was submitted to the NIST Post-Quantum Cryptography standardization process
• Offers security based on the hardness of decoding structured codes

The publication provides algorithmic descriptions, security analysis, and performance benchmarks.
