This is the homepage of the LEDAcrypt, a post-quantum asymmetric
cryptoscheme suite built on Quasi-Cyclic Low Density Parity Check
(QC-LDPC) codes. The suite includes a Key Encapsulation Method (KEM) and a
Public Key Cryptosystem (PKC), currently undergoing evaluation in the
second round of the NIST Post-Quantum Cryptography Standardization process.
Here we provide:
- The latest version of the cryptosystem specification
- An archive containing the reference implementation and optimized
implementations matching the submission to the second round of the NIST
Post Quantum Standardization Initiative
The old pages and submission packages for LEDAkem and LEDApkc are still
available for history tracking purposes; however they should be considered
superseded by LEDAcrypt.
