Distributed System Security Architecture or (DSSA) is a computer security architecture that provides a suite of functions including login, authentication, and access control 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.

On this system, individual happiness, etc. depend, and only in this connected system are they actualized and secured.”
—Georg Wilhelm Friedrich Hegel (1770–1831)

“The two elements the traveler first captures in the big city are extrahuman architecture and furious rhythm. Geometry and anguish. At first glance, the rhythm may be confused with gaiety, but when you look more closely at the mechanism of social life and the painful slavery of both men and machines, you see that it is nothing but a kind of typical, empty anguish that makes even crime and gangs forgivable means of escape.”
—Federico García Lorca (1898–1936)
