Abstract

Communication protocols implemented for CubeSat networks have trivial overhead and almost no security features. As CubeSats are heavily constrained for resources, complex security suites and protocols can seldom be implemented. Cyclic Redundancy Check (CRC) which is currently used in CubeSats provides no protection against intentional corruption of data and moreover, CubeSats are vulnerable to eavesdropping due to the wireless channel. Message integrity also becomes questionable as an attacker can modify commands and data. This paper proposes CubeSec and GndSec, a very light-weight security solution for CubeSats communications. CubeSec and GndSec provides mutual authentication, confidentiality, data integrity between Cubesat and ground Station using preshared keys.

CubeSec and GndSec: A Lightweight Security Solution for CubeSat Communications

Communication protocols implemented for CubeSat networks have trivial overhead and almost no security features. As CubeSats are heavily constrained for resources, complex security suites and protocols can seldom be implemented. Cyclic Redundancy Check (CRC) which is currently used in CubeSats provides no protection against intentional corruption of data and moreover, CubeSats are vulnerable to eavesdropping due to the wireless channel. Message integrity also becomes questionable as an attacker can modify commands and data. This paper proposes CubeSec and GndSec, a very light-weight security solution for CubeSats communications. CubeSec and GndSec provides mutual authentication, confidentiality, data integrity between Cubesat and ground Station using preshared keys.
