Showcase - Example Application

The example application realizes pseudonymous shopping with the aid of a trustee. The purchase is related to electronic goods (i.e. e-Books) which can be transferred via an already established TCP-IP connection. The trustee must be able to verify the completeness and correctness of the delivery.

Requirements and Constraints

In the presented scenario there are three types of participants, further called roles. These are the customer, the trader and the trustee. Thenames Alice, Bob and Charlie are used for easier referral.

Types of pseudonyms for the customer (Alice):

transaction pseudonym
person, role, rolerelation and role relation pseudonym (won't mean any advantage)

Types of pseudonyms for the trader (Bob):

certified person or role pseudonym
transaction pseudonym (less trustworthy)

Types of pseudonyms for the trustee (Charlie):

certified person or role pseudonym
no transaction pseudonym, because his correct behavior won't be provable

Architecture

Every participant has its own, small application, which uses the identity manager to establish connections, choose pseudonyms and sign documents.
