LEDAcrypt Home

Welcome to the LEDAcrypt homepage. LEDAcrypt is a suite of post-quantum asymmetric cryptosystems built on quasi-cyclic low density parity check codes, obtained as a merger of the LEDAkem and LEDApkc submission to the NIST Post-Quantum Cryptography Standardization process.

Here you can find both their specification and the public domain codebase implementing them.

The LEDAcrypt ciphersuite is currently submitted for consideration to the second round NIST Post-Quantum Cryptography Standardization process by the following team (listed in lexicographic order):
