SYSTEM FOR GENERATING SIGNCRIPTION OF WIRELESS MOBIE COMMUNICATION

摘要

The purpose of the present invention is to improve safety of data communication performed in a predetermined application environment by efficiently providing confidentiality and integrity in a wireless mobile communication environment. More specifically, the present invention calculates most operations in advance in an offline state and completes signcryption on information requested in very small operations when there is an operation request such as authentication. The present invention has properties which allow the invention to overcome limitations on the calculation capacity of a device used in communications and has cryptographal functions for various information protection services so that it can have high safety.
