Abstract: A communication method and a communications device, where the communication method includes: When a user equipment roams from a first network to a second network, a first core network device receives a first request, where the first request is a user authentication request or an authentication data request, where the first request carries an authentication vector request indication, where the second network is a 5G standalone network, where the first network is a 5G non-standalone network, and where the first core network device is in the first network. The first core network device generates an authentication vector quintet based on the authentication vector request indication, where a 0th bit of an authentication management field in the authentication vector quintet is set to 1. The first core network device sends a response to the first request, where the response to the first request carries the authentication vector quintet.

Abstract: In a method for enabling a message receive end to quickly confirm a certificate status, a defined field of a certificate includes classification information of the certificate, and a defined field of a certificate revocation list includes classification information of a revoked certificate, so that the receive end can quickly narrow a searching or matching range in massive records of the certificate revocation list based on the classification information carried in the certificate of a transmit end.
