To　improve　the　implementation　efficiency　of　conference　key　agreement　protocol　with　fault　tolerance,　this　paper　presents　a　conference　key　agreement　protocol　with　forward　secrecy　by　using　Elliptic　Curve　Digital　Signature　Algorithm　and　elliptic　curve　Diffie-Hellman　key　exchange　protocol.　Based　on　the　intractability　of　the　Elliptic　Curve　Discrete　Logarithm　Problem,　honest　participants　can　agree　on　a　common　conference　key　no　matter　how　many　malicious　participants　are,　and　passive　adversaries　get　no　information　about　the　conference　key　established　by　honest　participants.　Compared　with　the　existing　schemes　at　the　same　security　level,　the　proposed　scheme　requires　much　less　computation　and　communication　cost.
