Cloud Computing is a product of fusion of traditional computer and network technology developments such as Grid Computing (Grid Computing), distributed Computing (Distributed Computing), parallel Computing (Parallel Computing), utility Computing (Utility Computing), network storage (Network Storage Technologies), virtualization (Virtualization), load balancing (Load balancing), and the like.
With the development of the internet, real-time data flow and diversification of connected devices, and the promotion of demands of search services, social networks, mobile commerce, open collaboration and the like, cloud computing is rapidly developed. Unlike the previous parallel distributed computing, the generation of cloud computing will promote the revolutionary transformation of the whole internet mode and enterprise management mode in concept.
Cloud storage (cloud storage) is a new concept that extends and develops in the concept of cloud computing, and a distributed cloud storage system (hereinafter referred to as a storage system for short) refers to a storage system that integrates a large number of storage devices (storage devices are also referred to as storage nodes) of various types in a network to work cooperatively through application software or application interfaces through functions such as cluster application, grid technology, and a distributed storage file system, so as to provide data storage and service access functions for the outside.
The following describes the technical scheme of the application through several embodiments.
Referring to fig. 2, a flowchart of a method for detecting errors of an electronic signature according to an embodiment of the present application is shown. In this embodiment, the method is mainly applied to the terminal in the implementation environment shown in fig. 1 for illustration. The method may comprise the following steps:
In the embodiment of the application, the terminal can acquire the signature to be detected and meta information of the signature to be detected so as to conveniently detect whether the signature to be detected is correct or not.
The signature to be detected refers to an electronic signature provided by a user. The meta information refers to information used for generating a signature to be detected, and may include a key identification (SecretId), a key (SecretKey), a request Method (Method), a URI (Uniform Resource Identifier ), a signature valid time, and the like.
The key identification can be distributed to the user by the cloud server and is used for identifying the identity of the user; the key is also distributed to the user by the server and used for encrypting the signature character string and the cloud server verifies the identity of the user; the key identification is paired with the key.
The request method refers to an HTTP (Hyper Text Transfer Protocol ) request method for defining a field describing how to process a specified resource; the request method may include GET, POST, PUT, DELETE, etc.; wherein the GET is used to issue a request to a particular resource; the POST is used for submitting data to the appointed resource to process the request; the PUT is used for uploading the latest content to the appointed resource position; DELETE is used to request the server to DELETE a resource. Further, HEAD, CONNECT, OPTIONS and TRACE, etc. may be included.
A URI is a string used to identify a name of an internet resource, such as an HTML (HyperText Markup Language ) document, image, video clip, program, etc., that is located by a URI.
After acquiring the meta information, the terminal can generate a correct signature according to the meta information.
The steps of the process for generating the correct signature are described in the embodiment of fig. 3 below, and are not repeated here.
In step 203, if the signature to be detected is different from the correct signature, an error signature is generated according to the meta information and the reference error cause.
After generating the correct signature, the terminal may compare the to-be-detected signature with the correct signature, and if the to-be-detected signature is different from the correct signature, it indicates that the to-be-detected signature generated by the user is incorrect. In this case, the terminal may further generate an error signature according to the meta information and the reference error cause.
In addition, if the signature to be detected is the same as the correct signature, the signature to be detected generated by the user is correct. In this case, the terminal may directly feed back this detection result to the user to prompt the user that the signature to be detected that it generates is correct.
In step 204, the error cause of the signature to be detected is determined by comparing the signature to be detected with the error signature.
After generating the error signature, the terminal may compare the signature to be detected with the error signature. Since the error signature is generated according to the meta information and the reference error cause, if the to-be-detected signature is identical to the error signature, the cause of the to-be-detected signature error is identical to the reference error cause for generating the error signature, so that the error cause of the to-be-detected signature can be determined.
In summary, according to the technical solution provided in the embodiments of the present application, when the signature to be detected is different from the correct signature, an error signature is generated according to meta information and a reference error cause of the signature to be detected, and the error cause of the signature to be detected is determined based on the error signature. Compared with the related art, the technical scheme provided by the embodiment of the application can automatically detect whether the electronic signature generated by the user is correct or not, and automatically detect the error reason under the condition that the electronic signature is wrong, so that the error detection efficiency of the electronic signature is improved, the experience of using cloud services by the user is improved, and the threshold of using the cloud services by the user is reduced.
Referring to fig. 3, a flowchart of an error detection method of an electronic signature according to another embodiment of the present application is shown. In this embodiment, the method is mainly applied to the terminal in the implementation environment shown in fig. 1 for illustration. The method may comprise the following steps:
When a user requests to use a cloud server, a cloud service request (which may also be referred to as an HTTP signature request) is sent to the server, and the cloud service request is used to request use of a cloud service. After receiving the cloud service request, the cloud server performs identity verification on the user, namely, verifies the electronic signature provided by the user.
The request information comprises a signature to be detected and meta information of the signature to be detected, so that the cloud server can verify the electronic signature after receiving the cloud service request.
And step 302, analyzing the request information to obtain the signature to be detected and meta information.
Alternatively, the terminal may parse the request information according to a standard HTTP protocol to obtain the signature to be detected and meta information of the signature to be detected.
After the meta information of the signature to be detected is obtained, a correct signature may be generated.
Optionally, referring to fig. 4 in combination, the generation of the correct signature from the meta information may include the following steps:
(1) A key identification (SecretId) and a key (SecretKey) are obtained.
After acquiring the HTTP signature request, the terminal may parse the HTTP signature request according to a standard HTTP protocol, so as to obtain a key identifier and a key. The key identification and the key may be a character string consisting of numbers and letters.
For example, secretid= "AKIDc9 yimrbcfk 4C8sbmXQ8i65XXXXXXXXXX";
SecretKey＝"LUSE4nPK1d4tX5SHyXv6tZXXXXXXXXXX"
(2) Signature valid time (KeyTime) is generated.
The Unix timestamp StartTimestamp corresponding to the current time is obtained, and the Unix timestamp is the total number of seconds from UTC (coordinated universal time, or GMT greenwich time) 1970, 1 month, 1 day, 0 minute, 0 second (Beijing time 1970, 1 month, 1 day, 8 hours, 0 minute, 0 second). And calculating a Unix timestamp EndTimestamp corresponding to the signature expiration time according to the timestamp and the expected signature valid duration. The signature effective time is obtained by splicing, and the format is StartTimestamp; endTimestam. For example, the signature validity time may be denoted as 1557902800;1557910000.
optionally, the signature valid time may be input by the user, and correspondingly, the terminal may acquire the signature valid time input by the user.
(3) A request method is determined.
The terminal may determine the request method from the HTTP signature request described above.
For example, assume that an HTTP signature request includes: "GET/sample object (% E8%85% BE% E8% AE% AF% E4% BA% 91)? response-content-type=application%2Foctet-stream & response-cache-control=max-age%3D600 HTTP/1.1
Date:Thu,16 May 2019 06:55:53 GMT
Host:examplebucket-1250000000.cos.ap-beijing.myqcloud.com
……”；
It can be known that the request method is GET.
(4) A URI is obtained.
The terminal may obtain the URI from the HTTP signature request.
For example, assume that an HTTP signature request includes: "GET/sample object (% E8%85% BE% E8% AE% AF% E4% BA% 91)? response-content-type=application%2Foctet-stream & response-cache-control=max-age%3D600 HTTP/1.1
Date:Thu,16 May 2019 06:55:53 GMT
Host:examplebucket-1250000000.cos.ap-beijing.myqcloud.com
……”；
As can be seen, uri=response-cache-control; response-content-type.
(5) The request parameters (HttpParameters) and the request header (httppheaders) are obtained.
The request parameters and the request header refer to the request parameters and the request header of the HTTP signature request.
For example, assume that an HTTP signature request includes: "GET/sample object (% E8%85% BE% E8% AE% AF% E4% BA% 91)? response-content-type=application%2Foctet-stream & response-cache-control=max-age%3D600 HTTP/1.1
Date:Thu,16 May 2019 06:55:53 GMT
Host:examplebucket-1250000000.cos.ap-beijing.myqcloud.com
……”；
It can be known that httpparameters=response-cache-control=max-age% 3d600& response-content-type=application% 2Foctet-stream;
HttpHeaders＝date＝Thu％2C％2016％20May％202019％2006％3A55％3A53％20GMT&host＝examplebucket-1250000000.cos.ap-beijing.myqcloud.com。
(6) A signing key (SignKey) is generated.
The signing key is generated based on the key and the signing validity time.
Illustratively, a message digest (hash value) is calculated using HMAC-SHA1 with the key as the key and the signature validity time as the message, resulting in a signature key.
(7) A request string (HttpString) is generated.
The request string is generated by combining the request method, the URI, the request parameters, and the request header in a specific manner.
(8) A signature original string (stringtosgn) is generated.
And generating a signature original text character string according to the signature valid time and the request character string.
Illustratively, the message digest is calculated using HMAC-SHA1 with the signature validity time as a key, with the request string as the new message, resulting in a signed original string. Can be expressed as: stringtosgn=sha1\nfekytime\nsha 1 (HttpString) \n.
For example, the signature valid time is: 1510109254;1510109314; the request string is: 35601c3365a361b62b980fda754318c29862d39c, the signature original string stringtosgn=sha1\n 1510109254; 1510109314/n 35601c3365a361b 620fda 754318c29862d39 c/n.
(9) An electronic signature is generated.
And calculating a message digest by using the HMAC-SHA1 and the signature original text string as a message by using the signature key as a key to generate an electronic signature. Can be expressed as: signature=HMAC-SHA 1 (SignKey, stringToSign).
For example, the signing key is: a4501294d3a835f8dab6caf5c19837dd19eef357; the signature original text character string is ha1\n1510109254; 1510109314/n 35601c3365a361b 620fda 754318c29862d39 c/n; then the electronic Signature signature=hmac-SHA 1 (a 4501294d3a835f8dab6caf5c19837dd19eef357, ha1\n1510109254;1510109314\n35601c3365a361b 62980fda 754318c29862d39 c\n) =2c 53900d3fe8d2e875db8a6af5fe7303ee1567a8.
After generating the correct signature, the terminal may compare the to-be-detected signature with the correct signature, and if the to-be-detected signature is different from the correct signature, it indicates that the to-be-detected signature generated by the user is incorrect. In this case, the terminal may generate at least one error cause chain. Wherein each error cause chain includes at least one reference error cause.
The above-mentioned reference error causes are sorted according to some common error causes frequently fed back by users.
Illustratively, the reference error cause may be that the request method is capitalized; or the request parameters are not ordered according to the dictionary; it is also possible to include an underline in the request parameters; it may also be that the request header is capitalized, and so on.
Since the user may have more than one error in the process of generating the electronic signature, that is, the error cause of one electronic signature may include a plurality of, i.e., a chain of error causes. Alternatively, when the number of reference error causes is n, the number of error cause chains is 2 n -1, n is a positive integer。
For example, one chain of error causes may include the request method being capitalized and the request parameters not being ordered by dictionary; another chain of error causes may include request parameters that are not ordered by dictionary, request parameters that include underlining, and request header capitalization.
In practice, common error reasons fed back by the user can be continuously collected, so that reference error reasons can be expanded, and the detection accuracy can be further improved.
At step 305, at least one error signature is generated based on the meta information and at least one chain of error causes.
After the at least one error cause chain is obtained, at least one error signature may be generated from the at least one error cause chain and the meta information.
Alternatively, when the number of error cause chains is 2 n -1, generating at least one said error signature from the meta-information and at least one chain of error causes, may comprise: according to meta information and 2 n -1 chain of error causes, generating 2 n -1 false signature.
After generating at least one error signature, the terminal may compare whether the target error signature identical to the signature to be detected exists in the respective error signatures
If the target error signature exists, the reference error cause included in the error cause chain for generating the target error signature is determined as the error cause of the signature to be detected in step 307.
After comparing each error signature with the signature to be detected, if the target error signature identical to the signature to be detected exists, it can be determined that the user has a reference error reason included in an error reason chain for generating the target error signature in the process of generating the signature to be detected, so that the reference error reason included in the error reason chain for generating the target error signature can be determined as the error reason of the signature to be detected.
In addition, after comparing each error signature with the signature to be detected, if the target error signature identical to the signature to be detected does not exist, the failure of detecting the error causes is indicated. In this case, the terminal may directly feed back to the user failure to detect the error cause, and prompt the user to check the error cause according to the document.
Illustratively, as shown in FIG. 5, a flow chart is illustratively shown for determining the cause of an error in a signature to be detected. The terminal can collect some common error reasons frequently fed back by the user, and arrange n reference error reasons, such as reference error reason 1, reference error reason 2, reference error reason 3, and up to reference error reason n. Based on the n reference error causes, 2 can be generated n -1 a chain of error causes; and according to meta information and 2 n -1 chain of error causes, generate 2 n -1 false signature. Then, whether the target error signature which is the same as the signature to be detected exists in each error signature can be compared, and if the target error signature exists, the reference error reasons included in the error reason chain for generating the target error signature are determined to be the error reasons of the signature to be detected; if the target error signature does not exist, the failure of detecting the error reason is indicated.
In summary, according to the technical solution provided in the embodiments of the present application, when the to-be-detected signature is different from the correct signature, at least one error signature may be generated according to the meta information and at least one error cause chain, and after comparing each error signature with the to-be-detected signature, there is a target error signature identical to the to-be-detected signature, then a reference error cause included in the error cause chain for generating the target error signature may be determined as the error cause of the to-be-detected signature. According to the technical scheme provided by the embodiment of the application, the detailed error reason of the error of the electronic signature of the user can be intelligently detected, the error detection efficiency of the electronic signature is improved, the experience of using the cloud service by the user is improved, and the threshold of using the cloud service by the user is reduced.
In addition, according to the technical scheme provided by the embodiment of the application, a user does not need to request a technician to analyze and detect, and the labor cost is reduced.
The following describes the beneficial effects of the technical solution provided in the present application from the product side.
Referring to fig. 6, a flowchart of an error detection method of an electronic signature according to another embodiment of the present application is shown. In this embodiment, the method is mainly applied to the terminal in the implementation environment shown in fig. 1 for illustration. The method may comprise the following steps:
When the user needs to perform electronic signature detection, the error detection page can be displayed in the terminal. The error detection page is used for inputting a signature to be detected by a user to detect the electronic signature.
Alternatively, as shown in fig. 7, the error detection page 70 includes a request information input field 71, where the request information input field 71 is used for a user to input an electronic signature 711 to be detected and meta information 712 of the signature to be detected. The meta information about the signature to be detected has been described above and will not be described in detail here.
Optionally, the detection page 70 further includes a key input field 72, where the key input field 72 is used for the user to input the electronically signed key. The key is described in detail above and will not be described here again.
The user inputs the signature to be detected and meta information of the signature to be detected in the detection page, and correspondingly, the terminal can acquire the signature to be detected and the meta information of the signature to be detected, which are input in the detection page.
After the signature to be detected is obtained, the terminal can detect the signature to be detected. After receiving the detection instruction, the terminal may display a detection result of the signature to be detected. The detection instruction is used for triggering detection of the signature to be detected.
Optionally, as shown in fig. 7, a detection control 73 may be included in the detection page 70, and the user may click on the detection control 73 to trigger the detection instruction. In addition, the user can trigger the detection instruction through physical keys, gestures, voices and the like. The embodiments of the present application are not limited in this regard.
In step 604, when the detection result is that the signature is wrong, an error reason of the signature to be detected is displayed.
If the signature to be detected is wrong, the terminal can display the error reason of the signature to be detected.
