LEDApkc Public Key Cryptosystem

This is the homepage of the LEDApkc public key cryptosystem, a post-quantum asymmetric cryptoscheme relying on Quasi-Cyclic Low Density Parity Check (QC-LDPC) codes.

This page is provided as a permalink, the LEDApkc proposal was merged onto the LEDAcrypt ciphersuite.

Here we provide:

  • The latest version of the cryptosystem specification
  • An archive containing the reference implementation as per the original submission to the NIST Post Quantum Standardization Initiative
  • An updated archive containing the last version of the codebase, including updated code parameters: latest version

The specification both the specification and the codebase contain a changelog detailing updates and clarifications with respect to the document submitted to NIST, available as the [NIST submission package]
