  • Publication number: 20050232421
    Abstract: A method of generating a secure transaction log recording transaction data established between a first 10 and a second 20 data processing device. The transaction log includes transaction data derived from the first device that is digitally signed by the second device, and then digitally re-signed by the first device, with copies being stored locally to both devices. Any interference with the data by either device, or during transfer of data between them is evident to both devices. The transaction data may include data received and signed by an independent third party as a trusted third party.

  • Publication number: 20050163065
    Abstract: Telecommunication systems comprising terminals (1) and network-units (10) for exchanging messages via messaging servers (11) for client-to-client information are provided with detectors (7,14) for detecting control instructions and generators (6,15) for generating control instructions. The messages are provided with these control instructions for controlling interactions between terminals (1) and network-units (10). As a result, messaging servers (11) can now control different kinds of interactions in as well as across different kinds of networks. Said messages further comprise origin and destination identifications. Said control instructions comprise authentication instructions for authenticating said interaction, capability instructions or set up instruction for setting up a communication. Said messages can be in the form of XML messages. Bridging servers (30) bridge the gap between parties which can communicate with messaging servers (11) and parties which cannot.
