Secrecy Codes for Telemetry Links

This paper provides an introduction of finite blocklength secrecy coding over binary erasure wire-tap channels (BEWCs) with noisy main channels. We summarize recent results, give examples, and outline their potential use in aeronautical mobile telemetry (AMT). Secrecy (or wiretap) codes are capable of providing reliable communications to intended parties while also keeping data secure from illegitimate network users. The dual nature of these codes makes them of interest to AMT, as security is a major concern during the transmission of telemetry data on test ranges.
