Abstract: A method for sensing a traffic environment for use in an electronic device is provided. The method includes: generating local object information by sensing an environment within a first sensing range of the electronic device, wherein the local object information at least includes first geographical distribution information of local objects within the first sensing range; receiving external object information transmitted by at least one node, wherein the external object information includes at least second geographical distribution information of external objects within a second sensing range of the node; and generating object integration information according to the local object information and the external object information.

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.
