1. A method for securely accessing a device, comprising:
obtaining access authentication information via an out-band channel, the access authentication information being used for access authentication between a service request device and a service providing device, the service request device and the service providing device sharing the same management device, and forming the out-band channel with the management device respectively; authenticating the access authentication information; providing, by the service providing device, when an authentication result indicates that the access authentication information is authenticated, service for the service request device via an in-band data channel, the service providing device and the service request device forming the in-band data channel via a service network, and prior to obtaining the access authentication information via the out-band channel, generating and storing, by the service request device, the access authentication information, and sending, by the service request device, a service request to the service providing device via the in-band data channel, the service request comprising the access authentication information; wherein obtaining the access authentication information via the out-band channel comprises: receiving, by the service request device via the out-band channel, the access authentication information from the service providing device; and wherein authenticating the access authentication information comprises: performing, by the service request device, validity authentication on the received access authentication information according to the stored access authentication information, and sending the authentication result to the service providing device via the out-band channel.
