Efficient Transmission of DoD PKI Certificates in Tactical Networks

摘要

In tactical networks, transmission of DoD PKI digital certificates can create unnecessary burden on low-bandwidth links, increase response time for users, and drain radio power. In this paper we present a simple and practical approach to alleviating this problem. We develop a DoD PKI-specific compression dictionary that can be used to prime general purpose compression of certificates, resulting in a significant reduction of certificate sizes. We evaluate this approach using a sizable and diverse dataset of real DoD PKI certificates. Our evaluation suggests that the transmission and storage sizes of DoD PIG certificates can be reliably reduced by about 50%.
