A daemon for secure smart card support in the encrypted file system Transcrypt

Abstract Transcrypt[1] is an encrypted file system which uses a smart,card to store unique private parameters of users. This smart card is needed,for all file operations by the user of Transcrypt. For accessing the smart card, a user space daemon is used. This daemon,should be able to provide secure access to the smart card without compromising,the level of security which Transcrypt aims to achieve. Transcrypt adopts a kernel space only approach,and does not trust even the superuser. It prevents against both online and offline attacks. This project aims to explore the possible methods,of developing, this daemon,and implementing,the best case possible. 12,April,2007 5 Contents
