Specifically, as can be seen from fig. 1, the system may be composed of a product release server and a plurality of user side devices, wherein each user side device includes a verification module 14 and a result processing module 16, and the development signature module 10 and the release module 12 are disposed in the product release server.
In some embodiments of the present application, the workflow of the virtualized product integrity verification system depicted in FIG. 1 is shown in FIG. 2, comprising the steps of:
step S202, a signature development module initializes a signature file;
in the technical solution provided in step S202, the development signature module 10 may sign the target virtualized product, the key files and the key dependent files in the product installation package of the target virtualized product, and the production information of the target virtualized product, to obtain the signature file of the target virtualized product.
Step S204, the publishing module provides a target virtualized product, a signature file of the target virtualized product and a public key corresponding to each user side;
step S206, the verification module verifies the signature file according to the public key;
in the technical solution provided in step S206, the step of verifying the signature file by the verification module 14 according to the public key includes: verifying the signature file, and calculating to obtain a target hash value corresponding to the target virtualized product according to a verification result; and comparing the target hash value with an expected hash value corresponding to the target virtualized product, and determining whether the target virtualized product is complete or not according to a comparison result.
Step S208, the result processing module determines whether to run the target virtualized product according to the verification result, and reports the abnormal information under the condition that the target virtualized product cannot be run.
In the above operating environment, the embodiment of the present application provides a method for verifying the integrity of a virtualized product, as shown in fig. 3, the method includes the following steps:
step S302, a target virtualized product and signature files of the target virtualized product are obtained, wherein the signature files are key files and key dependent files in product installation packages of the target virtualized product and the target virtualized product, and files obtained by signing production information of the target virtualized product, and the production information comprises producer information and production equipment information;

Specifically, when signing the target virtualized product, any signature algorithm or key can be adopted to sign the target virtualized product, so as to obtain a signature file. The type of signature algorithm, the key generation method, the format of the signature file, and the like are not limited in this application. For example, the key may be a key generated by any encryption algorithm, such as RSA, DSA, ECC. The digital signature may be a signature generated by any type of signature algorithm, such as MD5, SHA1, SHA256, etc. The signature file may also be in any type of file format, such as TXT, XML, JSON. Signing the target virtualized product includes signing metadata of the target virtualized product, key files in the target virtualized product, and key dependent software.
As an alternative embodiment, the key file, the key dependent software, the respective metadata, etc. may also be signed separately.
By signing the key files and the key dependent software, other files in the installation environment can be prevented from polluting the installation process when the target virtualized program is installed on the user side equipment. For example, depending software used when different versions of program files or different versions of virtualized products are installed may remain in the user side device, so as to avoid installation failure caused by calling the residual program files of different versions or using the dependent software pollution installation process corresponding to the versions in the installation process, signature verification can be performed on the used key files and key dependent software. Therefore, only the program files and key dependent software which pass signature verification can be called, and the failure of the installation process caused by pollution of residual files in the installation process is avoided.
In addition, as different versions of the target virtualized product can be responsible for development and maintenance by different development centers and developers, the verification object can be rapidly determined under the condition that the integrity of the target virtualized product is determined to be damaged by writing the production equipment information of the development center corresponding to the target virtualized product, the physiological characteristic information of the producer and other identity verification information into the signature file, and the damage degree and the damage object of the target virtualized product can be determined by the verification object.
As an alternative implementation manner, the MAC address of the production machine that produces the installation package of the target virtualized product, the production time of the installation package, the feature value of the virtualized platform, the chip architecture value supported by the virtualized platform, and the identity authentication information (such as the physiological feature information such as the fingerprint value) of the producer that is responsible for producing the installation package can be used as data to be processed, and converted into a 16-system character string by adopting an arbitrary signature algorithm, and then the character string can be reversed by bits and then shifted to the right by two bits to obtain a unique signature, and written into the detailed field of the installation file in the installation package of the target virtualized product.
Step S304, verifying the signature file, and calculating according to the signature file after verification is passed to obtain a target hash value corresponding to the target virtualized product;

As an optional implementation manner, the signature file includes a first signature file corresponding to the target virtualized product and a second signature file corresponding to each installation file in the installation package of the target virtualized product, and the target hash value includes a second target hash value corresponding to each second signature file; the step of verifying the signature file and calculating the target hash value corresponding to the target virtualized product according to the verification result comprises the following steps: under the condition that the first signature files pass the verification, verifying each second signature file; and after verification, determining second target hash values corresponding to the second signature files according to the second signature files.
Specifically, the hash value corresponding to the signature file may be a hash value calculated using the signature file as an input parameter, or may be a hash value calculated from specific data recorded in the signature file.
In some embodiments of the present application, when a user obtains a target virtualized product and a signature file of the target virtualized product from a product publisher, the user may also obtain public keys allocated to the user by the publisher, and the public keys obtained by each user are different. Thus, the step of verifying the signature file further comprises: obtaining public keys of target virtualized products, wherein the public keys corresponding to different users are different; and verifying the signature file through the public key, and sending the public key and address information corresponding to the user to the issuer of the target virtualized product in the verification process, wherein the public key and the address information corresponding to the user are used for determining a tampered object of the signature file tampered with the target virtualized product under the condition that the signature file of the target virtualized product is detected to be tampered with.
As an alternative implementation, when the user installs or runs the virtualized program product, an operation log containing operation information of the user on the product, a public key allocated to the user and an IP address of the user is generated according to preset rules, and the log document is fed back to the product publisher. The product publisher can determine whether a user performs illegal operations according to the operation log, such as tampering a product signature, tampering a file in an installation package and the like, which can damage the integrity of the target virtualized product, and locate, according to the distributed public key and IP, who specifically damages the integrity of the target virtualized product after determining that the illegal operations occur.
Step S306, comparing the target hash value with an expected hash value corresponding to the target virtualized product, and determining whether the target virtualized product is complete according to the comparison result, wherein the expected hash value is a hash value corresponding to the expected state of the target virtualized product.
