Abstract: Embodiments of the present invention are directed to methods and systems for generating and revoking, as well as validating, certificates used to protect communications within networks while maintaining privacy protection. In the context of a method, certificate generation and revocation with privacy preservation comprises determining a secret value to be used by a certificate authority and an entity; constructing a key tree based on the secret value, wherein the leaves of the key tree represent derived keys for the certificates for the entity; and generating certificates for the entity based in part on the key tree leaves. The method further comprises determining that one or more of the certificates should be revoked; determining a minimum key node set that covers the certificates to be revoked; adding the minimum key node set to a certificate revocation list; and providing the certificate revocation list to one or more entities. Corresponding apparatuses and computer program products are also provided.

Abstract: A security certificate management method for a vehicular network node is applied in a vehicular network. A message is received. Whether a certificate in the message is revoked is determined. If the certificate in the message is revoked, a regional certificate revocation list (RCRL) is generated or updated based on the revoked certificate by the vehicular network node, and the RCRL is transmitted into a communication range of the vehicular network node.

Abstract: 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 only covers the first certificate and other revoked certificate in the key tree. When the first root node only covers the first certificate and the 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.

Abstract: An inter-vehicle communication see-through warning method includes steps below. A first image is captured from a first field of view of a front vehicle and a second image is captured from a second field of view of a rear vehicle. One or more first objects are identified in the first image. One or more second objects are identified in the second image. In response to determining that the one or more first objects include one or more first risk objects, corresponding first risk object information is transmitted to the rear vehicle. One or more first target objects among the first risk objects that are not the second objects are marked in the displayed second image according to the first risk object information.
