Embodiment approach

[0063] In order to ensure subsequent signature verification using a certificate containing a trusted certificate number to ensure the legitimacy of the information broadcast by the broadcasting system, as an implementation manner, the method further includes steps: A1, A2 and A3.

[0064] A1: Receive the certificate number to be signed.

[0065] The information including the certificate numbers to be verified for signature is received in real time or irregularly, wherein the number of the certificate numbers to be verified may be one, two or more.

[0066] Wherein, the information includes: signature information and at least one certificate number to be verified; wherein, in this embodiment, the signature information is a signature operation performed on the certificate number to be verified by using the SM2-SM3 algorithm , the obtained signature information. In other embodiments, other signature algorithms may also be used to perform a signature operation on the certificate ...

Abstract

The invention provides an information processing method and device, a chip, a terminal and an electronic device. The method comprises the steps of receiving a certificate, wherein the certificate comprises a certificate number; and when it is determined that the certificate number exists in a pre-stored trusted certificate number, updating a pre-stored historical certificate including the certificate number by using the certificate. After the certificate is received, the pre-stored historical certificate with the same certificate number as the certificate is updated by using the certificate, so that the pre-stored certificate is updated in time, and the information security problem caused by the fact that the stored certificate is not updated all the time is avoided; and meanwhile, the problem of signature verification failure due to the fact that the stored certificate is not updated in time is solved.

Description

technical field [0001] The present application relates to the technical field of information security, and in particular, to an information processing method, apparatus, chip, terminal and electronic device. Background technique [0002] In the existing emergency broadcast system, in order to ensure the security of the broadcast message, the pre-stored certificate is usually used to verify the broadcast message. However, in the prior art, when the pre-stored certificate is used for signature verification, the It is easy to have information security problems, and it is easy to cause the problem of signature verification failure. SUMMARY OF THE INVENTION [0003] In view of this, the purpose of the embodiments of the present application is to provide an information processing method, apparatus, chip, terminal and electronic device to solve the above problems. [0004] In a first aspect, an embodiment of the present application provides an information processing method, the ...
