The design of multiparty un-disavowal mutual signature arithmetic protocol in emergency response system

In the environment of the human working life, all kinds of unexpected events often occurred, to improve the emergency response capabilities and establish fast and efficient electronic incident command system is to be completed by all levels of government affairs, in which the security of information exchange is one of the key issues; in view of this, the needs of information exchange in the emergency system were introduced; the transfer process and encryption of information exchange business and the problem of multi-digital signature to be solved in the emergency system was analyzed; the information exchange model and its affairs which must be achieved in the emergency system was given; the detailed design of a multi-user information signature algorithm, authentication algorithm, and an undeniable sign of the algorithms in each agreement, the algorithm is the agreement of the relevant parameters and algorithms calculation complexity was analyzed. The secure transmission problem of information exchange in the emergency system was resolved; the efficiency and reliability of emergency command system was improved.
