There are many reasons such as the outburst of gas , penetrator , wrong operation , disabled monitor and malfunction from equipments etc . except man - made and outburst accidents , equipments malfunction takes great proportionment . therefore , a complete security and real - time monitor system of a coal mine based on large equipment is urgent to be development for high frequency of mine accidents 近年來,我國煤礦安全事故頻頻發生,原因有瓦斯突出、透水滲水、非法操作、監控失效和設備故障等造成,除了人為和突發事件外,設備故障引起的事故也占不小的比例,因此建立完整的煤礦大型設備實時監測系統非常必要。

Correspondence means that each time a principal b completes a run of the protocol as responder using x , which to b appears to be a run with a , then there is a unique run of the protocol with the principal a as initiator using x , which to a appears to be a run with b . secrecy means that messages protected by the protocol can be known by any penetrator 然后基于strand空間模型給出了其嚴謹周密的正確性證明。 mb協議的正確性主要體現在兩個方面:認證屬性:當協議主體以某參數完成協議后,被認證主體也必須以該參數參與協議運行。秘密屬性:保護協議消息不會泄漏給未被授權的主體。
