摘要： A method for determining the position of a mobile node applied to a roadside unit (RSU) is provided. The RSU and a plurality of mobile nodes form a communication network of a road. The method includes the steps of: obtaining, by , via at least one sensor, first road information, wherein the first road information provides absolute position distribution information associated with the mobile nodes; receiving, by a communication device, second road information from a first mobile node of the mobile nodes, wherein the second road information provides relative position distribution information associated with the first mobile node and second mobile nodes adjacent to the first mobile node; and determining, by a comparison device, the position of the first mobile node on the road according to the first road information and the second road information.

摘要： A certificate management method and a certificate management device are disclosed. The certificate management device includes a key collection computing unit, a certificate revocation unit, and a certificate revocation list broadcast unit. The certificate management method includes determining to at least revoke a first certificate in certificates that are recorded in a key tree and related to an entity, and determining whether a first root node covers one first certificate and one other revoked certificate in the key tree. When the first root node covers one first certificate and one other revoked certificate, information about the first root node is added to a certificate revocation list. The certificate revocation list is sent to another entity at least.

摘要： Apparatuses and methods for certificate generation, certificate revocation and certificate verification are provided. The certificate generation and revocation apparatus includes: a key set computation unit receiving a secret value and a hash function set and generating a key set of an entity; a hash function unit generating the hash function set; a certificate generation unit generating certificates corresponding to the public/private key pairs and the key set; a certificate revocation unit acquiring derived secret key corresponding to a revoked certificate set and updating a certificate revocation list; and a certificate revocation list broadcast unit broadcasting the certificate revocation list; wherein the secret value corresponds to a root of a key tree, wherein the key set is generated by leaves of the key tree, wherein each node of the key tree is generated by a randomly selected hash function.
