Identity management means, that a person basically can choose, how
anonymously respectively with which personal information and how accountable he
or she appears to his or her communication partner.
Identity management may be seen different points of view. At the end of this section is summarized, which of the presented points below are considered in the resulting realization, that is described in the next two sections.
Number of partners involved in the communication:We only take into account bidirectional communications with one partner based on the protocol TCP/IP. These are typical for client/server-based applications like e-Commerce and access to information in the WWW.
Pseudonyms, by the means of the presented architecture, are pairs of
cryptographic keys used for identification and digital signature.
They are linked with usage constraints (onetime, always, depending on role
or partner), related data and usage dates.
Each communication partner uses one pseudonym for a single communication
with the other.
Depending on the usage constraints and circumstances another pseudonym may
be chosen for later communication to the same partner.
