s1, obtaining the encrypted resource packet, and decrypting the encrypted resource packet to obtain a decrypted resource packet.

In the embodiment of the present invention, the encrypted resource packet may be constructed according to an original resource packet. For example, the original resource package is an H5 offline resource package for performing offline update on a client (such as APP), and a service person adds a resource file to the resource package directory through a standard H5 command to obtain the original resource package.

Further, each resource file in the original resource package may be traversed, hash processing may be performed on contents in the resource file to obtain a hash value of the resource file, a relative path between the resource file and the original resource package is obtained, the relative path is used as a value of a key, the hash value is used as a value of a value, an index key value pair (key-value) is constructed, each resource file in the original resource package may be accurately recorded by using the index key value pair, all the index key value pairs are summarized to obtain an index file, hash processing is performed on the index file to obtain an index hash value, and the index file and the index hash value are assembled to the original resource package to obtain the encrypted resource package.

In an optional embodiment of the present invention, the hash process (hash code) may convert any data into a data string with a fixed length, that is, a hash value, through an algorithm function, so as to improve security of resource file transmission. Meanwhile, the index file and the index hash value set can be encrypted by using an encryption algorithm, wherein the encryption algorithm can be an RSA algorithm and the like.

Specifically, the decrypting the encrypted resource packet to obtain a decrypted resource packet includes:

In the embodiment of the invention, the RSA algorithm is taken as an example, the RSA algorithm includes an encryption private key and a decryption public key, for example, bank a issues a patch resource package of a bank client for all users to update, first, bank a prints a digital signature on the patch resource package (namely, encrypts and issues the resource package by using the encryption private key of bank a), and the user needs to install a digital certificate of bank a (namely, the decryption public key issued by the bank to the outside) in a computer, and the digital certificate decrypts the digital signature of the resource package, so that the patch is successfully decrypted and used, and meanwhile, the source of the patch can be confirmed to be bank a indeed.

and if the index file hash value is consistent with the index hash value, determining that the index file is not tampered, and determining that the first accuracy check passes.

In an embodiment of the present invention, the preset first hash algorithm may be an MD5 algorithm. Due to the irreversibility of the hash algorithm and the characteristic that the same hash value can be generated for the same content, whether the index file is tampered or not can be accurately judged by comparing the index file hash value with the index hash value recorded in the decryption resource packet.

if the hash value is inconsistent with the resource hash value, determining that the resource file does not pass a second accuracy check;

and if the hash value is consistent with the resource hash value, determining that the resource file passes a second accuracy check.

In the embodiment of the invention, because the index file comprises the relative path of the resource file and the hash value of the content of the index file, if the content of the resource file is not tampered, the hash value searched by the relative path is consistent with the resource hash value of the resource file, and meanwhile, the relative path is taken as the index, so that the speed of searching the hash value can be improved, and the hash comparison rate in resource verification is further increased.

And S5, acquiring the resource files passing the second accuracy check in the resource file set according to the second accuracy check result.

By checking the content of the target resource file again, the resource updating accuracy can be ensured, and the safety of resource updating is improved.

In the embodiment of the invention, when any one of the first accuracy check, the second accuracy check and the security check fails, an abnormal alarm can be sent to the user in real time so as to improve the maintainability of resource updating.

For example, the above-described apparatus embodiments are merely illustrative, and for example, the division of the modules is only one logical functional division, and other divisions may be realized in practice.

The modules described as separate parts may or may not be physically separate, and parts displayed as modules may or may not be physical units, may be located in one place, or may be distributed on a plurality of network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of the present embodiment.

In addition, functional modules in the embodiments of the present invention may be integrated into one processing unit, or each unit may exist alone physically, or two or more units are integrated into one unit. The integrated unit can be realized in a form of hardware, or in a form of hardware plus a software functional module.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.

The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims shall not be construed as limiting the claim concerned.

The block chain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. A block chain (Blockchain), which is essentially a decentralized database, is a series of data blocks associated by using a cryptographic method, and each data block contains information of a batch of network transactions, so as to verify the validity (anti-counterfeiting) of the information and generate a next block. The blockchain may include a blockchain underlying platform, a platform product service layer, an application service layer, and the like.

Furthermore, it is obvious that the word "comprising" does not exclude other elements or steps, and the singular does not exclude the plural. A plurality of units or means recited in the system claims may also be implemented by one unit or means in software or hardware. The terms second, etc. are used to denote names, but not any particular order.

Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
