Method and system for secure handling of electronic business transactions on the internet

摘要

Disclosed is a computer-based technology for handling end-to-end business transactions in a TCP/IP-environment. A managing instance enables logon and provides a pool of IP addresses available for allocation. The managing instance allocates an IP address from the pool and establishes a tunneling IP connection between the managing instance and a user's device. The user's IP address together with any attributes relevant for accounting, authentication and authorization (AAA) are stored during the session time. The correlation between a user's authentication name and an IP address assigned to that name as well as the book-keeping of the validity of that correlation is handled using a session context. Any identification process for a user/subscriber who would like to use any service offered by an e-Service provider will be conducted solely using the assigned IP address.
