Abstract

This work proposes a Certification Authorities organization in order to achieve secure open communications. The report considers current international ongoing works as well as existing practices. Actually, our work tries to solve the present shortcomings when trying to organize a hierarchical CAs structure based on a naming hierarchy. The proposal focuses in the idea of having certification and naming separated, thus both hierarchies are not related anymore at the starting point, however it can be further related at application level. An important point is the provided architectural semantics for developing initial and further growing up certification hierarchies. In this way, current systems like PGP or RIPEM can be initially set up and further grown to more global structures.
