Ist nur eine elektronische Kommunikation moglich, gibt es einen solchen sicheren Kanal in aller Regel nicht. Eine essentielle Voraussetzung fur die Nutzung von Public-Key-Verschlusselung ist die Bindung der offentlichen Schlussel an den Namen ihres jeweiligen Inhabers., Abstract: Public key cryptography and the key certification needed to apply it will be a building block of confidential and authentic communication on the Internet and hence of its wide-spread use in research, commerce and everyday communication. To enable and promote the use of public key cryptography, especially among the members of the Freie Universitat Berlin (FU Berlin), a concept is presented for the installation and subsequent operating of a public key certification authority (CA) for the FU. The concept proposes the certification according to two slightly different sets of certification guidelines (policies) derived from the respective policies of the DFN PCA project, one with basic security requirements, the so-called "low-level policy," and one policy with enhanced security requirements, resulting in a "medium level" of security. The low-level certification may be performed mobile "on location" on the occasion of, e.g. events like the University's summer fest, whereas the mediumlevel certification is allowed to take place only in-house in the rooms of the computer centre of the FU Berlin (ZEDAT) that will host the FU CA. This two-way strategy shall enable the CA to better promote itself and its services among the members of the university, as this is deemed essential"
