PSMAN - Database Interface for Pseudonym Management

Purpose of this class library is the creation of an efficient and versatile persistence and management layer for pseudonyms and their related data.

Requirements and Constraints

The pseudonym management provides a mediation layer (middleware) to map pseudonyms and related data to systems for persistence. These include files in filesystems, database management systems and the like.

Number of pseudonyms per user:

1 (MS Passport)
>> 1

Properties of pseudonyms:

Keypair for signing
Usage (onetime, allways, related to communication partner)
Related data (name, age, shoe size)
Usage in transactions

Usage:

Relational Databases(MySQL, PostgreSQL, Sybase, ...)
Filesystem (XML-file)

Every user gets its own instance of the mediation layer to provide the persistence he or she needs. Therein he/she may place the pseudonyms for logging and reuse.
Every pseudonym gets saved with all properties, related data and the exact circumstances of its usage. They contain the usage resp. communication date and time, the partner involved as well as the released or collected data.
