Abstract
A security module is configured to provide an owner the capability to differentiate between users. In particular, the security module is configured to generate an asymmetric read/write key pair for respectively decrypting/encrypting data for storage on a disk. The owner of the file may distribute the read key of the asymmetric key pair to a group of users that the owner has assigned read-permission for the encrypted data.
