Special Encryption Considerations for Unattended Ground Sensor Systems

摘要

Requirements in Unattended Ground Sensor (UGS) systems have grown to include data privacy, message authentication, and anti-spoofing measures. This presents a challenge to the systems architect to consider approaches that defend against known and unknown attacks designed to compromise the system integrity. Encryption has been the preferred method to address these requirements. Encryption may be used to increase our confidence in the data transmitted in sensor networks, but requires greater, not less, attention to system security. After all, in an unencrypted network, at least we "know" that an adversary can read our data.
