Problems solved by technology

However, if a large number of installation packages are signed and an information digest is generated for the files in the installation package, it will cause repeated generation of information digests for a large number of duplicate files, resulting in more time-consuming generation of information digests, resulting in longer time consumption for installation package signing. Many, which in turn leads to low efficiency of installation package signing

Abstract

The invention discloses an installation package signature method and device, relates to the field of information technology, and solves the problem of large amount of time consumption in installation package signature in the prior art and the resulting low efficiency of installation package signature. The method of the invention comprises the steps of loading an installation package to be signed; determining whether or not a file in the installation package to be signed has been subjected to message digest processing; if determining that the message digest processing has been performed, obtaining a message digest file from the installation package, the message digest file being for recording a message digest of the file; performing signature for the message digest file to obtain a signature file; and adding the signature file to the installation package to be signed to complete the signature. The invention is mainly used for the signature of the installation package.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method and device for signing an installation package. Background technique [0002] In the mobile terminal operating system, the software installation package needs to be signed to be recognized and installed by the system. By signing the software installation package, the integrity of information transmission, the identity authentication of the sender can be guaranteed, and denial of transactions can be prevented. Signature technology refers to encrypting the summary information of the file with the private key of the sender, and then transmitting it to the receiver together with the original text. The recipient can only decrypt the encrypted summary information with the sent public key, and then use the hash function to generate a summary information for the received original text, and compare it with the decrypted summary information. If they are the same, it means t...
