摘　　要：针对目前密钥分配仍需要安全信道的不足,结合基于ID下密钥产生的优点和BLS短签名方案的长处,第一次构造了一个基于ID的无需安全信道的(t,n)门限密钥分配方案,并对其代价和安全性进行了分析。该方案在电子商务等方面有着广泛的应用。Recently the cryptographic key distribution still needs the safe channel. Aiming at the shortage of safe channel,an ID-based （t,n） threshold cryptographic key distribution scheme, which does not need the safe channel, and analysis of its cost and security were discussed. The scheme combines the advantages of ID-based cryptol graphic key and the BLS short signature and has broad application in electronic business.
