Yumin Wang · Jisuanji gongcheng · 2011
To solve the problems of hard to maintain system and manage key in practical applications of the full disk encryption mode,this paper puts forward a full disk encryption scheme based on logic password lock by using the generation key structure of two-layer based on password lock.Techniques of dynamic group key and secret splitting and threshold access for security parameters are applied in the scheme,so the scheme achieves respective accesses by multi-users and free storage disk key.Theory analysis and experimental results show that the scheme has higher security and its performance is better than its counterparts.
