【Abstract】 The encryption system E0, which is used in bluetooth , is introduced and examined. And then a method of deriving the cipher key from a set of known keystream bits is given. An improvement on E0, based on the way of attacking means described in the paper , is made. In the end, some theory analysis and sample data are provided from the new E0 system.更多还原
