Contemporary level of scientific and technical development is due to sharing relevant information and in this case it is very important to organize access to various informational systems with protected informational resources. Implementation of right instruments for interaction with informational systems for research and educational communities is a real necessity and will have essential contribution to increase capacity for knowledge access. Information systems development trends are reinforced by international projects with different destinations but with a common purpose: scientific and technical development and R&E society stimulation. Such projects are implemented as services and they are accessible to all interested community, but by realization of access rules and approached that are based on digital certificates, identity management, auto identification and authorization systems implementation. Many services and informational resources in the pan-European GÉANT network and connected Research and Educational networks require implementation of Public Keys Infrastructure and identity management technology.
