SECURITY SYSTEM OF MOVING OBJECT INFORMATION AND SECURITY METHOD OF MOVING OBJECT INFORMATION USING THE SYSTEM

摘要

A moving object information security system and method for improving security for moving object information in an intelligent distributed computing environment are disclosed. Such a mobile object security system includes a mobile object control device, N intermediate connection devices, a server, and a user terminal. The server generates a public key and a secret key, provides a public key to the mobile object control apparatus, generates N distributed information using the secret key, and transmits N distributed decryption apparatuses composed of N intermediate connection apparatuses to N Respectively. The mobile object control apparatus encrypts moving object information using a public key to generate a cipher text, and provides the cipher text to the N distributed decryption apparatuses. The N distributed decryption apparatuses each generate N partial decryption information from the cipher text using N distributed information, respectively. The user terminal receives t partial decryption information from t distributed decryption apparatuses (where t is an integer satisfying 1? T? N) to generate moving object information. Thus, the security of the moving object information can be further enhanced.
