Abstract

Encryption file system such as eCryptfs can prevent the leakage of information when storage media is lost or stolen.But it can not guarantee the data security when many users online access the system at the same time,because once one user can access the encryption data,the other users can access the data too.A capability mechanism based on keys was put forward to solve the problem,and then the method was used to design and implement a multi-user encryption file system based on eCryptfs to ensure that only those users with keys can access the encryption data.
