eCryptfs: a Stacked Cryptographic Filesystem
The Stony Brook University (SUNY) File Systems and Storage Labs (FSL) (filesystems.org) has developed a stacked filesystem framework called FiST. eCryptfs is derived from Cryptfs, which is one of the example filesystems implemented in FiST. Unionfs is another popular stacked filesystem written by the SUNY FSL.
