| Research Abstract |
Today, cryptographic primitives such as encryption and digital signature schemes are fundamental and important to establish various and complex systems in the modern society of computers and networks. Considering security of the systems in the future, it is desirable to provide cryptographic primitives whose security can be guaranteed for a long time. In this research project, we successfully developed such cryptographic primitives concerning to encryption, signatures and their applications. Since our contribution lies in proposing new mechanisms of cryptographic primitives whose security does not depend on any computational model, we hope that our research results can contribute to the development of construction of security systems in the future.
