  • Method for detecting a speed violation of a vehicle
    Patent number: 8964984
    Abstract: Detecting a speed violation of a vehicle traveling from a first roadside system to a second roadside system comprises: protecting evidence data collected at two roadside systems by encrypting each set of data with random session keys at each roadside system, and then encrypting the random session keys with a public key generated from an identity that may include a vehicle identifier and a timestamp. A ratio of the public keys is calculated and used to detect a violation, whereupon a private key is obtained for decrypting at least one of the encrypted session keys, and decrypting at least one of the encrypted evidence data with the decrypted session key.
