An Efficient Rate Blackbox Algorithm

Agent is a computer software procedure, it works in the dynamic environment and has the high autonomous ability, but also it has many merits: the independency, the cooperation, the adaptability to the tendency and the flexibility of the environment, the reduction of correspondence expenses and the support for fault-tolerant and so on. Time limited blackbox algorithm can not protect input and output of agent, for example, malicious host may refuse the transfer of agent or return wrong result; It is very difficult to choose a mechanism of conversion for protecting host; agent must realize the clock synchronization with the running environment, which reduces the security of blockbox algorithm. Because time limited blackbox algorithm exists shortage, the paper puts forward an efficient rate blackbox algorithm, which is without time restriction, more safe valid and higher practical value.
