Quantum Resistant Public Key Cryptography

Yongge Wang

We develop post-quantum (or quantum resistant) public key encryption techniques. Our first implementation is based on the Random Linear Code Based Public Key Encryption Shceme (RLCE) which was recently introduced by Dr. Yongge Wang. The full package (including library and C codes for key generation, encryption, and decryption) is available at here: RLCE.tar.gz

RLCE Performance

The following Table shows the comparison of the RLCE performance against OpenSSL RSA performance. Both RSA and RLCE were tested with a MacOS Sierra on a MacBook Pro with 2.9 GHz Intel Core i7. The time is in miliseconds.

RLCE Parameters

The following Table lists the parameters for the RLCE encryption scheme with equivalent AES-128, AES-192, and AES-256 security levels. The Tabble also lists the sizes for the corresponding public key, private key, and message bandwidth

Tools and Software for Download

RLCE parameter package: RLCE.jar (19KB). RLCE.jar will test the security strength for given parameters and calculates the padding parameters. It runs on all platforms. For instructions, run: java -jar RLCE.jar
