Abstract
Recent works have shown great potentials for enhancing satellite communications (SATCOM) in terms of security and privacy from blockchains and smart contracts. However, smart contracts deployed on the blockchain also suffer from various attacks, e.g., illegal trigger and access, continuous intrusion, which causes critical threats toward blockchain-based SATCOM. In this paper, we first design a token-based access control mechanism for smart contracts with dynamic adjustment of the access control rules (ACRs), which guarantees that only authorized users can trigger and execute specific smart contracts. We then propose an intrusion detection mechanism for smart contracts to detect attacks against smart contracts in an effective and real-time way. Based on these mechanisms, we propose an access control and intrusion detection framework, dubbed ACID, to resist various attacks while remaining all characteristics and functionalities of the underlying blockchain-based SATCOM system. We conduct a comprehensive evaluation, which demonstrates that ACID is secure, feasible, and efficient.
