Problems solved by technology

[0023] 1. When accessing the website through the HTTP protocol in a public WIFI environment, there is a potential risk of information being stolen during data transmission
[0024] 2. After the portable smart terminal is lost, the important data stored in the terminal is not guaranteed
[0025] 3. It will not automatically clear the URL access traces, which may lead to the leakage of users' private information
[0026] 4. In addition, there are similar unsafe factors in the transmission protocol supported by the browser and the cookie mechanism
In fact, it is also a matter of data security

Embodiment 1

[0067] Embodiment 1 provides a secure communication method between the smart terminal and the server of the present invention.

[0068] Such as image 3 As shown, it shows the overall structure diagram of the communication between the client and the target server of the present invention. Wherein, the client represents the current mobile smart terminal device, which may be a smart phone, a PDA, a tablet computer, a notebook computer or any other portable mobile communication device. And in order to solve the problem that the secure browser can send and receive ciphertext data normally, it is necessary to set up an HTTP proxy server locally on the client side, which is responsible for deciphering the data instead of the browser, sending the encrypted data to the target server through the gateway, and at the same time responsible for the target server. The data sent by the server to the client is decrypted, the decrypted data is sent to the client, and finally to the browser. ...

Embodiment 2

[0082] attached Figure 5 shows through Figure 4 A method for downloading files through a public secure browser data channel, the method comprising the following steps:

[0083] 1. The user visits the page with a secure browser and clicks on a link to request to open a file

[0084] 2. First judge whether the file already exists locally, if it exists, ask whether it needs to be overwritten and downloaded, if not, decrypt the file and display it. If the download is overwritten, it is as follows in point 3.

[0085] 3. Request the file from the target server, encrypt and store the returned request data locally, and use the ADE encryption algorithm to encrypt the file data stored locally.

[0086] 4. Decrypt and display the local files.

[0087] The files downloaded through the secure browser are encrypted and stored locally, and the files can only be viewed after identification. Therefore, if the mobile terminal is lost, the authorized user of the terminal cannot view the f...

Abstract

The invention discloses a method and device for having access to a webpage safely through an intelligent terminal. The system comprises the intelligent terminal and a browser located on the intelligent terminal, wherein the intelligent terminal is connected with a security server, and the security server and a target server are connected with a gateway. The method includes the steps that the intelligent terminal starts local monitoring service, and an HTTP proxy server of the browser is set as a local address; the browser receives an access request, and the access request is forwarded to a local designated port by means of the HTTP proxy server; after the intelligent terminal monitors and receives the access request of the browser, identity authentication is started; after authentication, request data are forwarded to the security server after being encrypted; after the security server decrypts the data, the data are sent to the target server; the security server receives response data, decrypts the response data and forwards the response data to a client; the client receives the response data, decrypts the response data and feeds back the response data to the browser.

Description

technical field [0001] The invention relates to the field of network security, in particular to a method and system for securely accessing webpages and downloading data by using an intelligent terminal. Background technique [0002] Acronyms and key term definitions [0003] Session: When a user browses a website, the time elapsed from entering the website to closing the browser, that is, the time spent by the user browsing the website [0004] Cookie: Generated by the server and sent to the User-Agent (usually a browser), the browser will save the key / value of the Cookie to a text file in a certain directory, and send the Cookie to the next time the same website is requested Server (provided your browser is set to enable cookies) [0005] PKI: Public Key Infrastructure, or "Public Key Infrastructure", is a key management platform that follows established standards. It can provide cryptographic services such as encryption and digital signatures and the necessary key and ce...
