Embodiment Construction

[0024] Embodiments of the present invention are described below with reference to the drawings.

[0025] 1. Construction of device identification system 1

[0026] As shown in FIG. 1, the device authentication system 1 includes a server device 100, a plurality of client devices 200a, . . . 200e, an Internet 300 and a router 400.

[0027] The server apparatus 100 stores contents of movies, music, etc., and distributes the contents to client apparatuses 200a to 200e for which an identifier (ID) and a password have been registered with the server apparatus 100 . The password may be registered with the server device 100 directly or remotely. For direct registration, the password to be registered is directly input into the server device 100 . For remote registration, a password to be registered is input into the client device 200 and then transmitted therefrom to the server device 100 .

[0028] As shown by the client devices 200a and 200b in FIG. 1 , each client device can comm...

Abstract

A device authentication system includes a server device and a client device that perform mutual authentication when content is transmitted from the server device to the client device. The client device receives challenge data from the server device, generates signature data based on the received challenge data and the first password, and transmits the generated signature data. The server device generates and sends challenge data, saves the second password in advance, receives the signature data from the client device, uses the challenge data and the second password to authenticate the received signature data, and when the authentication is successful, sends an encrypted password to the client device. Content.

Description

technical field [0001] The present invention relates to a device authentication system for mutual authentication between devices when transferring digital content between devices. Background technique [0002] In recent years, digital copyright works (hereinafter referred to as "content"), such as music, video, games, etc., have become easy to obtain due to the use of distribution methods such as the Internet, digital broadcasting, and package media. [0003] In order to prevent unauthorized use of the distributed content and to allow only authorized devices to use the content, the content is encrypted before distribution. [0004] Document 1 (identification given at the end of this section) discloses a specification called Digital Transmission Content Protection (DTCP). [0005] DTCP is a protection specification for digital content transmitted via IEEE1394 standardized bus, which is a high-speed serial bus standard. Each device using content has a secret key and a certif...
