| As an access tool for users to use the network,the browser is an important way for users to access the Internet.With the widespread use of B/S architecture,accessing the web interface of various websites and opening the web version of the application requires the browser to operate.In this process,the transmitted information will be sent to the network through the browser,which leads to a huge security risk.The user’s IP address and information content will be exposed during transmission,even if it has been protected by encryption,when the browser transmits When the address and content are still there,there is still the possibility of being obtained by hackers.Therefore,the security of the browser plays a very important role in the protection of user privacy.In view of the security issues of the browser,this article is designed based on the open source browser Firefox,and improves the security of the browser from two aspects.In the transmission between the two parties,the communication address and relationship between the two parties can be hidden so as to carry out anonymous transmission;the other is to encrypt the storage through the browser to protect the private content and prevent the leakage of user resources.Based on the above two aspects,the open source Firefox is designed and implemented,so that users can use the browser with the same appearance and regular functions as traditional Firefox,but with enhanced security functions.Based on the above,this article integrates the Tor proxy into the Firefox browser,so that Firefox can directly access the Tor anonymous network,so that the information is forwarded through three relay routes during the transmission process,and finally the purpose of information anonymity is obtained.In addition,the built-in database of the Firefox browser is used to realize the processing of user records and file storage and classification.The content is encrypted by AES-128 and the key is verified by MD5,so as to achieve the security protection effect of user privacy content.The final test shows that this paper implements a secure and stable Firefox browser that can provide information hiding. |
