Implementation of TPKI over WIN-T introduces technical challenges for PKI certificate validation due to lower bandwidth and higher latency than on strategic networks.
Testing results influenced development of the TPKI CONOPS and will help identify an optimal solution for distributing certificate revocation information to tactical systems, as well as to inform Army policy, requirements, Tactics, Techniques and Procedures, and configuration Best Business Practices for the implementation and deployment of PKI validation services within the Army tactical environment.
Looking ahead, TCM GNE, along with our SIGCoE and Army partners, will continue capabilities development and planning efforts towards implementation of TPKI.
This analysis will address some details of TPKI implementation that were outside the scope of the CONOPS.
Testing of TPKI certificate validation alternatives is ongoing and the results will help determine the solution chosen for implementation.
Regardless of the specific solution chosen, one thing is certain: TPKI will enhance the security and safety of Army computer networks by establishing an integrated capability that provides network access control, minimizes insider threats, and audits user activities across the cyber domains.
