`ABSTRACT
`
`A system and method relating to secure communications in
`a communication network is disclosed. The invention uses
`sessions having limited duration to enable parties to com-
`municate securely in the communication network. The ses-
`sion of one party is independent from the session of another
`party. The sessions are linked at a server which confirms that
`the sessions are valid.
`
`the secure communications
`In a preferred embodiment,
`occur in an electronic transfer system. In the electronic
`transfer system, a customer and a merchant can conduct a
`transaction wherein the customer can purchase a product
`from the merchant and pay for the product using electronic
`funds.
