Development of High-Speed Public-Key Cryptographic Algorithms based on Mathematical Hard Problems

Cryptographic algorithms should be used to prevent economic and personal damages in IoT environments. However, current international standard public-key cryptographic algorithms, RSA and ECC, are limited in their applications to resource constrained IoT devices due to their slow speeds. To resolve this this issue, we develop a next generation public-key cryptographic algorithms, which is secure against a quantum computer and is suitable for IoT devices. One of our goals is to derive as a candidate public-key cryptographic algorithm for a new international standard.
