Abstract

A method for device interaction includes: receiving identity authentication information input by a user in a case that a cross-device identity authentication function of a first device is enabled; and sending an identity authentication request to a second device that has established communication with the first device, wherein the identity authentication information is carried in the identity authentication request, and the identity authentication request is configured to request the second device in a locked state to perform identity authentication according to the identity authentication information.

First claim

What is claimed is:

1 . A device interaction method, comprising:
receiving identity authentication information input by a user in a case that a cross-device identity authentication function of a first device is enabled; and sending an identity authentication request to a second device that has established communication with the first device, wherein the identity authentication information is carried in the identity authentication request, and the identity authentication request is configured to request the second device in a locked state to perform identity authentication according to the identity authentication information.

2 . The method according to claim 1 , further comprising:
receiving first verification information; and enabling the cross-device identity authentication function of the first device in response to the first verification information being verified.

3 . The method according to claim 1 , further comprising:
acquiring first shared information; and before sending the identity authentication request to the second device that has established communication with the first device, the method further comprising: generating the identity authentication request according to the first shared information and the identity authentication information.

4 . The method according to claim 3 , wherein the generating the identity authentication request according to the first shared information and the identity authentication information comprises:
encrypting the identity authentication information according to the first shared information, to obtain ciphertext information; and generating the identity authentication request according to the ciphertext information.

5 . The method according to claim 4 , wherein the encrypting the identity authentication information according to the first shared information to obtain the ciphertext information comprises:
obtaining a first key and a second key according to the first shared information; encrypting the identity authentication information input by the user based on the first key, to obtain encrypted information of the first device; signing the encrypted information of the first device based on the second key, to obtain signature information of the first device; and splicing the signature information of the first device and the encrypted information of the first device, to obtain the ciphertext information.

6 . The method according to claim 5 , wherein the encrypting the identity authentication information input by the user based on the first key to obtain the encrypted information of the first device comprises:
performing data type conversion on the identity authentication information input by the user, to obtain the identity authentication information of byte array type; and encrypting the identity authentication information of byte array type using the first key, to obtain the encrypted information of the first device.

7 . A device interaction method, comprising:
receiving an identity authentication request sent by a first device that has established communication with a second device, wherein a cross-device identity authentication function of the second device is enabled and the second device is in a locked state; and performing identity authentication in response to the identity authentication request.

8 . The method according to claim 7 , further comprising:
receiving second verification information; and enabling the cross-device identity authentication function of the second device in response to the second verification information being verified.

9 . The method according to claim 7 , further comprising:
acquiring second shared information; and the performing identity authentication in response to the identity authentication request comprising: performing identity authentication based on the second shared information and the identity authentication request in response to the identity authentication request.

10 . The method according to claim 9 , wherein the performing identity authentication based on the second shared information and the identity authentication request comprises:
decrypting the identity authentication request based on the second shared information, to obtain decrypted information; and performing identity authentication on the second device based on the decrypted information.

11 . The method according to claim 10 , wherein decrypting the identity authentication request based on the second shared information to obtain decrypted information comprises:
obtaining key information of the second device based on the second shared information; and processing the identity authentication request based on the key information of the second device, to obtain the decrypted information.

12 . The method according to claim 11 , wherein the identity authentication request is generated based on ciphertext information; the key information of the second device comprises a first key and a second key; and the processing the identity authentication request based on the key information of the second device to obtain the decrypted information comprises:
splitting the ciphertext information to obtain split encrypted information and split signature information; judging whether ciphertext signature verification is successful based on the first key and the split signature information; and decrypting the split encrypted information using the second key in a case that the ciphertext signature verification is successful, to obtain the decrypted information.

13 . The method according to claim 12 , wherein the judging whether ciphertext signature verification is successful based on the first key and the split signature information comprises:
signing the split signature information using the first key to obtain signature verification information; and determining that the ciphertext signature verification is successful in a case that the signature verification information is same as the split signature information.

14 . The method according to claim 12 , further comprising:
stopping decryption of the split encrypted information in response to failure of the ciphertext signature verification.

15 . The method according to claim 7 , further comprising:
after the cross-device identity authentication function of the second device is enabled, detecting input information of the second device; and in response to the input information of the second device being used to represent disabling the cross-device identity authentication function, and identity verification of input user of the second device being verified, closing an entrance to the cross-device identity authentication function of the second device and deleting the key information of the second device.

16 . An electronic device, comprising:
a processor; and a memory configured to store instructions executable by the processor; wherein the processor is configured to: receive identity authentication information input by a user in a case that a cross-device identity authentication function of the electronic device is enabled; and send an identity authentication request to a second device that has established communication with the electronic device, wherein the identity authentication information is carried in the identity authentication request, and the identity authentication request is configured to request the second device in a locked state to perform identity authentication according to the identity authentication information.

17 . An electronic device, comprising:
a processor; and a memory configured to
