Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, the technical solution in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
Part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
All other embodiments obtained without creative efforts, belong to the scope of protection of the invention.
The embodiment of the present invention provides a kind of method of calibration of service packs, and this method is applied to a client.Fig. 1 is the present invention
The flow diagram of the method for calibration of service packs in embodiment, shown in Figure 1, this method includes：
S101：The service packs that server issues is obtained, includes multiple attached bags in service packs；
In the present invention is implemented, service packs includes header packet information, attached bag list and attached bag ciphertext, and attached bag list is included respectively
The sub-packet information of a attached bag, sub-packet information include the check code of the identifying of each attached bag, the size of each attached bag and each attached bag.
For example, 1. simplify format description：
2nd, list explanations are simplified：
Certainly, service packs can also there are other ways of realization, the present invention to be not specifically limited.
In other embodiments of the present invention, after S101, in order to ensure security, the above method can also include：Adjust
With signature check interface, signature check is carried out to service packs using public key；When being verified successfully to service packs, pass through kernel module
Public key is called, signature check is carried out to multiple attached bags.
Here, the signature check interface of client call itself, carries out service packs preliminary check, such as, calculated using RSA
Method, hash algorithm, DSA algorithms etc. carry out signature check, then, after verifying successfully, public key is called by kernel module, inside
Core state carries out signature check to multiple attached bags.
For example, signature check is carried out to service packs using RSA Algorithm, then, S101 can include：Obtain the bright of service packs
Literary and corresponding signature；Signature is decrypted using public key, obtains first message summary；Calculate corresponding second message in plain text
Summary；First message summary is compared with second message summary.
At this time, if first message summary compares unanimously with second message summary, show to verify successfully, conversely, then table
Bright authentication failed.In the case where being proved to be successful, following S102 is performed.
S102：Public key in kernel header file is called by kernel module, signature check is carried out to multiple attached bags.
Here, since public key is included in kernel header file, then, when carrying out signature check, kernel mould can be passed through
Block calls public key, comes to carry out signature check to each attached bag with this.At this time, RSA Algorithm can be still used, or using other label
Name checking algorithm, the embodiment of the present invention are not specifically limited.
In embodiments of the present invention, in order to secret key is transferred directly to kernel, then, should before signature check is carried out
Method can also include：When generating kernel mirror image, public key is converted into kernel header file；Compiled using kernel header file
Translate, generate kernel module.That is, public key is converted to kernel header file, kernel compiling is participated in, it is interior after compiling is completed
Core module directly can get public key in kernel state, without generating or transmitting other specification.
In other embodiments of the present invention, after public key is called by kernel module, public key can also be matched
Processing, the private key of adjustment input kernel module.
The embodiment of the present invention provides a kind of endorsement method of service packs, method of calibration and device, first, obtains under server
The service packs of hair, includes multiple attached bags in the service packs, then, the public key in kernel header file is called by kernel module,
Signature check is carried out to multiple attached bags.As it can be seen that public key is transmitted directly to kernel, verification operation is thus proceeded by, is eliminated
The generation and transmission of partial parameters, have shortened call flow, have reduced complexity, have it is of a relatively high and it is stronger can suitability
And portability, realize the kernel state signature check for possessing independence and low coupling.
Based on previous embodiment, the embodiment of the present invention also provides a kind of endorsement method of service packs, this method be applied to
The corresponding server of above-mentioned client.
Fig. 2 be the embodiment of the present invention in service packs endorsement method flow diagram, shown in Figure 2, this method
Including：
S201：A pair of of secret key of generation；
Here, server performs secret key Core Generator generation private key, and derives to corresponding public key.In practical applications,
Secret key Core Generator depends on OpenSSL environment.
S202：Secret key is converted into abstract syntax notation one ASN.1 types；
S203：The secret key of ASN.1 types is parsed, obtains final secret key；
Here, S202 to S203 can be that private key is first converted to the form of ASN.1 types by server, then, will
The private key of ASN.1 types parses, and is converted to final private key, for example, the private key of ASN.1 types is converted into character string, and
Character string is determined as to final private key.At this time, private key can be character string, and certain private key can also be binary numeral
String, at the same time, derives from final public key.In this way, server just obtains final secret key.
S204：Using the private key in final secret key, treat the service packs issued and sign.
Here, server operation signature tool, is signed using the private key in final secret key to service packs to be issued.
Specifically, it is exactly using private key, integrally signs to service packs, meanwhile, using private key, to multiple attached bags in service packs
Sign.In this way, client after service packs is received, first can carry out signature check to service packs, then in kernel state
Each attached bag is verified.
Further, it is correct in order to ensure signing, can also be in local runtime after signature tool is to patch packet signature
Calibration tool, verifies signature, after verifying successfully, which is sent to client.
So far, the generation of secret key is just completed.
