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 ...
in a 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 is the authentication protocol of DSSA. The CDC is a
