Distributed System Security Architecture or (DSSA) is a
computer security architecture that provides a suite of
functions including login, authentication, and
access control
In the fields of physical security and information security, access control (AC) is the selective restriction of access to a place or other resource, while access management describes the process. The act of ''accessing'' may mean consuming ...

distributed system. To differ from other similar architectures, the DSSA architecture offers the ability to access all these functions without the trusted
server (known as a
certificate authority) being active.
In DSSA, security objects are handled by owners and access is controlled by the central, universally trusted, certificate authority.
DSSA/SPX
DSSA/SPX is the
authentication protocol of DSSA. The CDC is a
