This paper describes an asynchronous state-machine replication system that tolerates Byzantine faults, which can be caused by malicious attacks or software errors. Our system is t...
In a recent work, we have shown that it is not possible to dependably build any type of distributed f fault or intrusiontolerant system under the asynchronous model. This result f...

Many Internet applications use overlay networks as their basic facilities, like resource sharing, collaborative computing, and so on. Considering the communication cost, most over...
The detection of unknown viruses is beyond the capability of many existing virus detection approaches. In this paper, we show how proactive customization of system behaviors can be...
