Formal Verification and Security Analysis of AMQP

AMQP, serving as the application layer standard protocol for advanced message queuing systems, has garnered widespread adoption in middleware systems, including Rab-bitMQ, ActiveMQ, and Qpid. However, the key properties and security of AMQP's messaging mechanism remain unverified. Hence, in this paper, we employ process algebra CSP to formalize the AMQP and verify properties such as deadlock freedom, data reachability, concurrency, sequence consistency, and scala-bility. The verification results indicate that AMQP satisfies these properties, demonstrating the reliability in message transmission. Moreover, to further analyze the security of AMQP messaging mechanism, the intruder model and SSL protocol model are introduced in this work. Meanwhile, the comparison of the verification results with and without SSL is also presented, showing an improvement of the AMQP messaging mechanism security.
