Patent ID: 8640223

Claim:
An auxiliary secure display system, including a client and a server that connects with the client through a network, wherein the client includes a main display unit which directly displays information received via a network, and an auxiliary display unit which comprises a security module; the server generates information to be displayed in the auxiliary display unit when the client accesses the server by means of the main display unit via the network, and uses a shared encryption key of the auxiliary display unit to encrypt the information; the security module uses the shared encryption key to verify the validity of the encrypted information provided by the server via the network to display the decrypted information in the auxiliary display unit, wherein when a security initialization is dominated by the client, in the case of the authentication center verifying the auxiliary display unit as valid according to a preset encryption key, the auxiliary display unit generates a digital certificate and submits it to the authentication center to be saved; the authentication center sends the digital certificate to the server, and feeds back the server initialization information sent back by the server to the client; and the auxiliary display unit updates the encrypted information of the server in the case of verifying initialization information of the server as valid, and wherein when a security initialization is being dominated by the server, in the case of the authentication center verifying the auxiliary display unit valid according to a preset encryption key, the authentication center generates a digital certificate, sends it to the client, and uses the preset encryption key to encrypt and sign the digital certificate; the authentication center sends the digital certificate to the server, and feeds back the server initialization information sent back by the server to the client; and the auxiliary display unit updates the encrypted information of the server in the case of verifying initialization information of the server as valid.
