Embodiment 1
[0054] Embodiment 1: Key-based authentication.
[0055] The networking of this embodiment is as follows figure 2 As shown, the PN is composed of a PN gateway, a PN device 1, and a PN device 2; the PN device 1 and the PN device 2 interact with the PN server through the PN gateway.
[0056] The key-based authentication process consists of the following steps:
[0057] Step 101, the PN server assigns a 128-bit seed to the PN gateway.
[0058] Step 102, the PN gateway generates random numbers for the PN device 1 and the PN device 2 respectively.
[0059] Step 103, the PN gateway generates a key for the PN device 1 according to the identifier of the PN device 1, the random number of the PN device 1, and the seed.
[0060] Step 104 , the PN gateway sends the key generated for the PN device 1 to the PN device 1 .
[0061] Step 105, the PN gateway generates a key for the PN device 2 according to the identifier of the PN device 2, the random number of the PN device 2, and the seed...
Embodiment 2
[0069] Embodiment 2: Authentication based on digital certificates.
[0070] The networking of this embodiment is as follows image 3 shown. Such as image 3 As shown, the PN is composed of PN gateway, PN device 1, and PN device 2; PN device 1 and PN device 2 interact with the PN server through the PN gateway; the PN server is connected to a third-party impartial agency , which is used to issue digital certificates.
[0071] The authentication process based on digital certificates includes the following steps:
[0072] Step 201, the device manufacturer builds a public key and a private key into the PN device 1 when producing it.
[0073] Step 202, the device manufacturer builds a public key and a private key into the PN device 2 when producing it.
[0074] Step 203, PN device 1 sends its public key to a third-party notary organization through the PN gateway and PN server to apply for a digital certificate.
[0075] Step 204, the third-party notary organization sends the d...

Abstract
The invention discloses an identification method used for identifying a personal area network device. The method comprises the steps of: identifying the personal area network device which initiates an interaction request by a personal area network gateway or a personal area network server when the personal area network device requires to perform interaction with the personal area network gateway or the personal area network server; and performing interaction between the personal area network device and the personal area network gateway or the personal area network server after passing of the identification. The invention further discloses an identification system used for identifying the personal area network device, an identification unit is used for identifying the personal area network device which initiates the interaction request by the personal area network gateway or the personal area network server when the personal area network device requires to perform interaction with the personal area network gateway or the personal area network server, and the interaction between the personal area network device and the personal area network gateway or the personal area network server is performed after passing of the identification. By adopting the method and the system disclosed by the invention, personal area network devices can be effectively identified in a personal area network when a large number of personal area network devices exist.
Description
technical field [0001] The invention relates to authentication technology, in particular to an authentication method and system for authenticating personal network equipment in a personal network. Background technique [0002] With the development of science and technology, people have more and more personal devices, such as mobile phones, laptops, PDAs, MP3s, MP4s, etc., and the capabilities of these devices are becoming stronger and stronger, most of which have short-distance communication capabilities Therefore, people increasingly hope to be able to connect these devices around them together to form a Personal Area Network (PN) to share resources and capabilities with each other. [0003] However, with the increasing number of PN devices in the PN, how to effectively authenticate these PN devices has become a very urgent problem. Currently, there is no effective solution to the problem of how to authenticate PN devices. . Contents of the invention [0004] In view of...
