LEDAcrypt

LEDAcrypt is a suite of post-quantum asymmetric cryptosystems built on quasi-cyclic low density parity check codes. LEDAcrypt was submitted to the second round of NIST’s Public-key Encryption and Key-establishment Algorithms for Post-Quantum Cryptography.

LEDAcrypt includes a KEM (Key Encapsulation Module) built from the Niederreiter cryptosystem, named LEDAcrypt KEM, and a PKC (Public-Key Cryptosystem) built from the McEliece cryptosystem, named LEDAcrypt PKC, both based on linear error-correcting codes.
