Summary	Many current communication channels rely largely on interactive cryptographic protocols to establish security. These protocols require real-time round-trips of synchronous interaction between devices and makes them susceptible to channel-tear down by adversaries as well as environmental effects ¿ subsequently leading to additional set-up time and increased electromagnetic footprint. Within a contested environment, such protocol use presents physical vulnerabilities to logistics due to the increased location detectability from the electromagnetic footprint as well as cyber security vulnerabilities. In particular, if an adversary compromises the communications channel, they can gain long-term access to the data. This research looks at addressing this problem through use of secure asynchronous protocols. Protocols supporting asynchronicity limit downtime, offering efficiency benefits under restricted communication. They furthermore have potentially attractive security features such as self-healing security in the event of adversarial compromise of a communications channel. This research applies CAC2S as a case study, framing the environment concerns to the contested restrictions anticipated.
