Abstract

A method for establishing a secured communication channel between a client and a server is disclosed where a program and a set of encryption information for establishing the secured communication channel are delivered from the server to the client. The set of encryption information is compact and can be used to quickly and efficiently encipher and decipher data. In particular, the client requests a program from the server via a first secured communication channel that can be established by a web browser under the HTTPS (Hypertext Transfer Protocol with SSL) protocol. The server in response dynamically generates a set of encryption information and a token identifying this particular set of encryption information. This information is then sent with the requested program. While the program can be written in any language, the language of choice is a platform-independent language such as Java. When the program executes on the client and performs its programmed tasks, one of the tasks is to establish a separate, secured communication channel with the server using the encryption information from the server.
