摘要： A pseudonym credential configuration method and apparatus are provided. The method includes: receiving an identifier of a terminal device and information about N to-be-requested pseudonym credentials from the terminal device, sending N second request messages to a pseudonym credential generation server, and storing a tag of each second request message in association with the identifier of the terminal device in the registration server, so that the registration server can obtain, based on the tag, the identifier that is of the terminal device and that is associated with the tag; and generating N pseudonym credentials. The pseudonym credential generated in this application may enable a behavior investigation server to learn of a real identity of the terminal device.

摘要： This document describes a system and method for managing communications between modules in a Controller Area Network (CAN) in a secure manner. In particular, the system employs a hierarchical key generation method that allows a module in the CAN to use a single ascendant key together with relevant identifiers to generate descendant keys for CAN identities in the Controller Area Network. These keys are then used by the broadcasting and receiving CAN modules to authenticate published messages.
