According to the method of claim 3, the first verification information includes one or more of the following: First value; A first identifier, wherein the first identifier is used to identify a first algorithm for generating the first feature value; The first value includes one or more of the following: First random number; Timestamp; The value of the counter.
The method according to claim 4, wherein the first algorithm is obtained by the first device from the fourth device.
A token transmission method, characterized in that the method includes: The second device obtains the first token after the first device has changed it. The first token is used for authentication when the first device and the second device communicate.
According to the method of claim 6, the first device acquires the first token by one or more of the following: The second device obtains the first token from the third device, and the first token is obtained by the third device from the first device; The second device obtains the first token from the first device through a communication connection established with the first device; The second device receives a broadcast message sent by the first device, the broadcast message including the first token.
The method according to claim 6 or 7, characterized in that the method further comprises: Verify the first token; If the first token passes verification, authentication is performed before the first device is used based on the first token.
The method according to claim 8, wherein the verification of the first token includes: First verification information and first feature value are determined based on the first token. The first feature value is generated by the first device based on the first verification information and a preset keyword. The preset keyword is negotiated in advance by the first device and the second device. A second feature value is generated based on the first verification information and the preset keyword; If the first feature value and the second feature value are the same, the first token is determined to have passed the verification; if the first feature value and the second feature value are not the same, the first token is determined to have failed the verification.
According to the method of claim 9, the first verification information includes one or more of the following: First value; A first identifier, wherein the first identifier is used to identify a first algorithm for generating the first feature value; The first value includes one or more of the following: First random number; Timestamp; The value of the counter.
The method according to claim 10, wherein the second feature value is generated according to the first algorithm; the first algorithm is obtained by the second device from the first device, or by the second device from the fourth device.
