    Abstract: This invention provides a method and system for data encryption and decryption in data transmission through the web. The method includes: a browser sends a cryptographic information acquisition request to a cryptographic information providing equipment; the cryptographic information providing equipment sends cryptographic information back to the browser via an HTTPS channel; the cryptographic information includes a cryptographic algorithm and a cryptographic index; the browser uses the cryptographic algorithm to encrypt the data to be transmitted, and sends the encrypted data and the cryptographic index to the web server via an HTTP channel; the web server obtains the cryptographic algorithm corresponding to the cryptographic index from the cryptographic information providing equipment, then decrypts the encrypted data. Embodiments of the present invention can alleviate the load in the HTTPS channel, and improve the overall performance.

    Abstract translation: 本发明提供了一种通过网络进行数据传输的数据加密和解密方法和系统。 该方法包括:浏览器向加密信息提供设备发送加密信息获取请求; 加密信息提供设备通过HTTPS通道将加密信息发送回浏览器; 密码信息包括密码算法和加密索引; 浏览器使用加密算法加密要发送的数据,并通过HTTP通道将加密数据和加密索引发送到Web服务器; Web服务器从加密信息提供设备获取与密码索引对应的加密算法,然后解密加密数据。 本发明的实施例可以减轻HTTPS信道中的负载,并提高整体性能。
