Abstract:
1. A method for verifying an access identity of a set-top box, comprising: receiving by a dynamic host configuration protocol (DHCP) server, a verification request message sent by a set-top box, wherein the verification request message carries option information of the DHCP server, which comprises: first identity cipher text information of the set-top box, software version information of the set-top box, and a user serial number, and the first identity cipher text information is generated by the set-top box according to identity information of the set-top box by using a first encryption algorithm, wherein the identity information of the set-top box comprises timestamp information when the set-top box calculates a first identity cipher text by using the first encryption algorithm or when the set-top box calculates a second identity cipher text by using a second encryption algorithm; forwarding by the DHCP server, the first identity cipher text information of the set-top box, the software version information of the set-top box, and the user serial number included in the option information to an authentication server; obtaining by the authentication server, the identity information of the set-top box from the first identity cipher text information according to the user serial number by using a preset first decryption algorithm; verifying by the authentication server, the identity information of the set-top box according to the software version information; and receiving by the authentication server, a decryption algorithm update indication message, wherein the decryption algorithm update indication message comprises a second decryption algorithm.
