摘要:

Distributed architecture is often adopted for the intrusion-tolerance system currently. However, this distributed intrusion- tolerance system has a consensus problem. To solve this problem, this article explores a distributed intrusion-tolerance system of hybrid time model based on trusted timely computing base (TTCB) and implement an atomic multicast protocol using TTCB services. The TTCB is a trust secure real-time component inside the server, with a well defined interface and separated from the operation system. It is in the synchronous communication environment, while the application layer in the server works asynchronously. By the atomic multicast protocol, it can be achieved that when the servers are over twice the number of faulty servers, the consensus can be satisfied. The performance evaluations show that the proposed protocol can yield larger good throughput with a lower unavailability.

Abstract:

Distributed architecture is often adopted for the intrusion-tolerance system currently. However, this distributed intrusion- tolerance system has a consensus problem. To solve this problem, this article explores a distributed intrusion-tolerance system of hybrid time model based on trusted timely computing base (TTCB) and implement an atomic multicast protocol using TTCB services. The TTCB is a trust secure real-time component inside the server, with a well defined interface and separated from the operation system. It is in the synchronous communication environment, while the application layer in the server works asynchronously. By the atomic multicast protocol, it can be achieved that when the servers are over twice the number of faulty servers, the consensus can be satisfied. The performance evaluations show that the proposed protocol can yield larger good throughput with a lower unavailability.
