Abstract
The utility model discloses a user Id safety certificate system used for an interactive digital television system, mainly comprising a set top box and a two-way access server connected with the set top box, wherein the two-way access server is connected with a two-way certificate server. The utility model also discloses a user Id safety certificate method used for the interactive digital television system. A two-way CAS platform adopting the utility model is safe and reliable, and a safe and reliable data transmitting channel is provided for value-added service such as VOD (Video-On-Demand), interactive games, stocks and the like, thus guaranteeing the safety of the two-way value-added service.
Description
Technical field
The utility model relates to a kind of user Id security certification system that is used for interactive digital TV systems.
Background technology
The passage that two-way value-added service is used is public the Internet, therefore inevitablely also can run into the safety problem that the Internet faces, as forged identity, illegally insert, intercept and capture other people privacy etc.Therefore, must there be a safety certification measure to guarantee the fail safe of two-way value-added service.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, and a kind of user Id security certification system that is used for interactive digital TV systems that can guarantee two-way value-added service fail safe is provided.
The purpose of this utility model is achieved through the following technical solutions: the user Id security certification system that is used for interactive digital TV systems, the main two-way access server that links to each other by set-top box and with set-top box constitutes, it is characterized in that described two-way access server is connected with the two-way authentication server.
Link to each other by the Internet between described set-top box and the two-way access server.
Link to each other by local area network (LAN) between described two-way access server and the two-way authentication server.
In sum, the beneficial effects of the utility model are: the way CAS platform safety that adopts the utility model to set up is reliable, for value-added services such as VOD, interactive game, stock provide safe and reliable data transmission channel, guaranteed the fail safe of two-way value-added service.
Description of drawings
Fig. 1 is the structural representation of Verification System of the present utility model;
Fig. 2 is the schematic flow sheet of authentication method of the present utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited only to this.
Embodiment:
As shown in Figure 1, the two-way access server that the Verification System that the utility model relates to mainly links to each other by set-top box and with set-top box constitutes, and described two-way access server is connected with the two-way authentication server; Link to each other by the Internet between described set-top box and the two-way access server; Link to each other by local area network (LAN) between described two-way access server and the two-way authentication server.
Based on the authentication method of above-mentioned Verification System, its verification process may further comprise the steps as shown in Figure 2:
(a) set-top box sends authentication request message S to two-way access server
r(C, P
A1), this message comprises: set-top box identity, set-top box ID, set-top box PKI etc.; And authentication request message is encrypted by triple complicated algorithms that RSA cryptographic algorithms, 3DES cryptographic algorithm and privately owned cryptographic algorithm combine.
(b) two-way access server is received set-top box authentication request message S
r(C, P
A1), if satisfy the form of request authentication, then with this authentication request message S
r(C, P
A1) be transmitted to the two-way authentication server; Two-way access server is simultaneously with self authentication request message S
r(B, P
A1) after encrypting, send to the two-way authentication server;
(c) the two-way authentication server is received the authentication request message of set-top box and two-way access server, after deciphering, obtains information such as the identity of set-top box and two-way access server and PKI; And relevant information encrypted and signature obtains digital certificate S
r(C, P
A2) and S
r(B, P
A2) after send to two-way access server;
(d) two-way access server receives the digital certificate S of set-top box and two-way access server
r(C, P
A2) and S
r(B, P
A2), obtain the PKI of set-top box through deciphering, and simultaneously two umber word certificates are transmitted to set-top box;
(e) two-way access server produces random session key K, session key K is encrypted the back produce S
r(K, P
B2, P
C1), send to set-top box;
(f) utilize session key K that time stamp T is encrypted, two-way access server carries out producing S behind the encrypted signature to message
r(T, K, P
B2, P
C1), send to set-top box;
(g) the set-top box deciphering obtains the PKI and the session key K of two-way access server, thereby between two-way access server and set-top box, set up escape way, and utilize session key K to verify the signature of two-way access server and the validity of time stamp T, whole authentication process finishes.
As mentioned above, just can realize the utility model preferably.
Claims (3)
1. the user Id security certification system that is used for interactive digital TV systems, mainly the two-way access server that links to each other by set-top box and with set-top box constitutes, and it is characterized in that described two-way access server is connected with the two-way authentication server.
2. the user Id security certification system that is used for interactive digital TV systems according to claim 1 is characterized in that, links to each other by the Internet between described set-top box and the two-way access server.
