LIGHTWEIGHT AUTHENTICATION KEY AGREEMENT METHOD BETWEEN TERMINALS

摘要

The present invention relates to a method for sharing a lightweighted authentication key between terminals, more particularly, to a method which includes: a step that a key generation center server generates a public key; a step that the key generation center server receives a unique ID from a first server and generating a private key and a public key for the first terminal based on the ID; a step that the first terminal receives the private key and public key, and determine a validity for the received private key and public key; and a step that the first terminal and second terminal share a session key through hash operation authentication. Owing to the method mentioned above, the method for sharing lightweighted authentication key between terminals can stably provide a wireless communication service without using many resources of a personal mobile terminal by using a lightweighted encryption process for a session key when performing wireless communication by accessing a cloud computing system using the personal mobile terminal having a restricted amount of resources.
