example 1-1

[0070] Example 1-1: The electronic device may use the target private key to sign the first information to obtain the first digital signature.

example 1-2

[0071] Example 1-2: The electronic device may use the target private key to sign the second information to obtain the second digital signature.

example 1-3

[0072] Example 1-3: The electronic device may use the target private key to sign the first information and the second information to obtain a third digital signature.

[0073] Specifically, if the electronic device collects the second information, the electronic device may not use the first information to perform a digital signature, that is, it may use the target private key to sign the second information, or use the target private key to sign the first information and the second information sign.

[0074]Based on this solution, if the electronic device needs to collect the second information, the electronic device can also use the second information as a parameter in obtaining the signature information, which can make the generated signature information more secure, so that the server can obtain the target In the case of device fingerprints, signature verification can also be performed in conjunction with the second information. In the case that the content in the second inf...

Abstract

The embodiment of the invention provides an equipment fingerprint verification method and device, relates to the technical field of communication, and aims to solve the problem of relatively low security of security authentication. The method comprises the following steps: receiving a target equipment fingerprint; under the condition that the target equipment fingerprint comprises first information and a digital signature, acquiring a target public key according to the first information, wherein the first information indicates an equipment unique identifier; verifying and signing a target private key corresponding to the digital signature according to the target public key; under the condition that signature verification succeeds, determining that the target equipment fingerprint is a safeequipment fingerprint, wherein the first information is associated with a target public key, and the digital signature is associated with a target private key, the equipment unique identifier, the target public key and the target private key are generated in TEE, and the target private key is stored in an RPMB of the electronic equipment.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a device fingerprint verification method and device. Background technique [0002] With the development of communication technology, users use electronic devices to pay more and more frequently, and the data security of electronic devices is also becoming more and more important. [0003] Usually, the device fingerprint is to generate the unique identification code of the electronic device by collecting the information of the electronic device, such as the international mobile equipment identity (international mobile equipment identity, IMEI), media access control address (media access control address, MAC) of the electronic device ) or Android identification (identity document, ID) and other information to generate the device fingerprint of the electronic device. The online risk control system can use the device fingerprint to verify whether ...
