Dynamic and heterogeneous Byzantine system in cloud
In order to improve the intrusion tolerance performance of cloud platforms
the Byzantine system model has been widely used.But the current Byzantine system is difficult to prevent a latent attack effectively
which can destroy the Byzantine system by accumulating the number of executive modules which the attacker controls and making it exceed the tolerance upper limit.To solve the problem
a dynamic and heterogeneous Byzantine system was proposed.In which the executive modules were maximized diversified in configurations such as different operating systems and so on.Meanwhile
every executive module was assigned a lifetime based on the attacker’s ability and the vulnerabilities of the module.The novel system can significantly enhance the intrusion tolerance of the cloud service by diverse and dynamic attack surface
