Trusted Computing Platform Alliance

from Wikipedia, the free encyclopedia

The Trusted Computing Platform Alliance ( TCPA ) was a consortium founded in 1999 by Microsoft , IBM , Hewlett-Packard and Compaq . About 200 companies from the hardware and software sector belonged to it. In April 2003 the TCPA was merged into the successor organization Trusted Computing Group (TCG).

The properties thus realized can also be used for digital rights management , which the TCPA members see only as a by-product of the specification.


Due to the veto right of all 200 members, the TCPA proved incapable of acting. As a result, the official successor organization Trusted Computing Group (TCG) was founded in April 2003 , which took over the specifications created up to that point and continues its further development.

The TCPA has been highly controversial since its inception. While proponents emphasized the higher level of security that it could bring to the fore, critics accused that TCPA would mainly be used for user control and monopolization.

During the lifetime of the TCPA (1999–2003), however, operating system manufacturers such as Microsoft did not succeed in fully developing an operating system based on it. The standardization activities of the TCPA will be continued with a revised statute of the successor organization Trusted Computing Group (TCG).
