The Key Authority - Secure Key Management in Hierarchical Public Key Infrastructures
We model a private key`s life cycle as a finite state machine. The states are
the key`s phases of life and the transition functions describe tasks to be done
with the key. Based on this we define and describe the key authority, a trust
center module, which potentiates the easy enforcement of secure management of
private keys in hierarchical public key infrastructures. This is done by
assembling all trust center tasks concerning the crucial handling of private
keys within one centralized module. As this module resides under full control
of the trust center`s carrier it can easily be protected by well-known
organizational and technical measures.Comment: 5 pages, 2 figure
Using LDAP Directories for Management of PKI Processes
We present a framework for extending the functionality of LDAP servers from their typical use as a public directory in public key infrastructures. In this framework the LDAP servers are used for administrating infrastructure processes. One application of this framework is a method for providing proof-of-possession, especially in the case of encryption keys. Another one is the secure delivery of software personal security environments
