Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1, an embodiment of the present invention provides a method for symmetric encryption transmission of sensitive data in a Web application page of a security unit, including the following steps:
S101: judging whether encryption operation is needed or not;
Specifically, two judging methods for encryption operation are provided in the present embodiment: an automatic encryption judging method and a manual encryption judging method. Wherein:
The automatic encryption judging method comprises the following steps: when the webpage is opened, monitoring whether the webpage has operation behaviors or not, and recording the operation time of the operation behaviors; if the time interval between the current monitoring time and the latest operation time is longer than the preset duration, the encryption operation is considered to be needed.
The judging method of the manual encryption is as follows: if the encryption request sent by the browser is received, the encryption operation is considered to be needed. The manual encryption is to send an encryption request to the Web server side by an operator on the browser side, as opposed to the automatic encryption. For example, in practical application, an encryption button may be set at the browser end where the Web page is located, and when the operator clicks the encryption button, the browser sends an encryption request to the Web server.
S102: when encryption is needed, an encryption key is defined;
s103: determining content to be encrypted in a webpage, and converting the content to be encrypted into binary content;
specifically, the determining the content to be encrypted in the webpage specifically includes: presetting sensitive information keywords; and then matching all the contents in the webpage with the sensitive information keywords, wherein the matched contents are the contents to be encrypted.
S104: performing binary operation on the binary content and the encryption key to obtain an encryption code;
S105: generating and storing a corresponding relation between the encryption code and a display position of the content to be encrypted in the webpage;
in particular, the correspondence should be stored on a protected physical medium.
S106: and when decryption is needed, restoring and displaying the content to be encrypted in the webpage according to the corresponding relation.
Specifically, when a decryption request sent from the browser side is received, decryption is considered necessary. When decryption is needed, prompting an operator to input identity credential information, verifying the identity credential information, and restoring and displaying the content to be encrypted in the webpage according to the corresponding relation after verification is successful.
For example, taking an encryption button as an example, when data is in an encryption state, the encryption button is automatically changed into a decryption button, when an operator clicks the decryption button, the browser sends a decryption request to the Web server side, then the browser side pops up a prompt box for inputting identity credential information, the operator inputs the identity credential information in the prompt box, the Web server verifies the identity credential information, and after verification, the decrypted data is sent to the browser and displayed in a Web page.
The method for symmetric encryption transmission of sensitive data in the secret related unit Web application webpage provided by the embodiment of the invention can well solve the following technical problems:
(1) For the first scenario mentioned in the background art, the embodiment of the invention can start the monitoring service from the moment when the operator starts to operate the Web page, and once the Web page is monitored to be not operated within a certain period of time (for example, 15 minutes or 30 minutes), the Web page is automatically encrypted (i.e., steps S102 to S105 are executed), so that an automatic start protection function is achieved, and thus leakage of sensitive information is avoided to a certain extent.
(2) For the second scenario mentioned in the background art, when an operator needs to cooperate with other operators to debug the computer together, the operator can send an encryption request to the Web server side at the browser side, and after the Web server receives the encryption request, the encryption service is started, and sensitive information in the Web page is protected (for example, sensitive data can be displayed as XXX), so that operation and maintenance personnel of software manufacturers can debug the computer under the condition that the sensitive information is invisible, thereby solving the contradiction and conflict between the protection of the sensitive information and the investigation problem.
(3) For the third scenario mentioned in the background art, before the transmission of the Web page content, the operator manually starts the encryption service (similar to the second scenario, i.e. the operator clicks the encryption button, which is not described here again), at this time, the content is in an encrypted state in the whole transmission process, and when the content needs to be displayed again, the operator must perform the second authentication and pass before the encrypted content can be displayed normally, even if someone can download the content in the physical medium, the content is encrypted and cannot be opened, and only through the normal opening mode (for example, the operator clicks the decryption button, the browser sends a decryption request to the Web server side, then the browser side pops up a prompt box for inputting the identity credential information, the operator inputs the identity credential information in the prompt box, and the Web server verifies the identity credential information and passes the verification), the encrypted content can be displayed normally on the Web page, thereby avoiding the leakage of the sensitive information to a certain extent.
As shown in fig. 2, the embodiment of the present invention further provides another method for symmetric encryption transmission of sensitive data in a Web application page of a security-related unit, which includes the following steps:
S201: when the webpage is opened, starting an encryption flow; the encryption flow comprises the following steps: defining an encryption key; determining content to be encrypted in a webpage, and converting the content to be encrypted into binary content; performing binary operation on the binary content and the encryption key to obtain an encryption code; generating and storing a corresponding relation between the encryption code and a display position of the content to be encrypted in the webpage;
for example, after the encryption flow is started, the display effect after the encryption processing of the sensitive information in the Web page is "XXX".
S202: if the operation behavior of storing the data of the webpage is monitored, decrypting the encrypted content at the Web server end so as to enable the service of storing the data to logically process the decrypted data service;
specifically, when the user saves the data, the encrypted data is decrypted at the Web server, and then Service can take the decrypted data to perform Service logic processing.
S203: after the business logic processing is completed, executing an encryption process again on the data at the Web server end, and storing the encrypted data in a database;
s204: when decryption is needed, the encrypted data is read from the database and displayed in the webpage, an operator is prompted to input identity credential information, the identity credential information is verified, and after verification is successful, the content to be encrypted is restored and displayed in the webpage according to the corresponding relation.
Specifically, when decryption is needed, the user clicks an unlocking button in the Web page, and after the secondary authentication is successful, the data is normally displayed.
Fig. 3 is a schematic diagram of a manual encryption and decryption flow. As can be seen from fig. 3, the flow is specifically: firstly, a browser sends an encryption or decryption request to a Web server, then a request processor at the Web server side processes the encryption or decryption request, judges whether the request is trusted, and if so, performs subsequent operations according to the corresponding request processing type: if the request is an encryption request, corresponding encryption service is carried out, and then data is returned to the browser after the data is packaged; and if the request is a decryption request, performing corresponding decryption service, and then, packaging the data and returning the data to the browser. If not, directly packaging the data, and then returning the data to the browser.
Fig. 4 to 8 are schematic diagrams illustrating the effects of the complete encryption and decryption processes according to the embodiments of the present invention.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
