System and method for the user certificate - -, - distribution and for - - locations available in converged wlan - wwan cooperating networks

摘要

A method for secure sequences in a converged cooperating network, comprising:– Obtaining a public key of a computing device (108);– Performing (208) of a bootstrapping - (bootstrap -) process with a network operator;– Obtained (210) of a first instance of a user certificate of the network operator, wherein the user certificate is based on the public key, and– Transmitting (214) of a second instance of the user certificate to the computing device (108) for purposes of the digital signature, verification and encryption,the converging means of the cooperation of network access and a wireless large surfaces network (wwan) and a wireless local area network (wlan), said first and second instance of the user certificate simultaneously and in each case in the wwan and wlan - networks are used, in order to authenticate a subscriber.
