ABSTRACT:
A technique for security and authentication on block-based media includes involves the use of protected keys, providing authentication and encryption primitives. A system according to the technique may include a secure device having a security kernel with protected keys. A disk drive security mechanism may support authentication of data, secrecy, and ticket validation using the security kernel and, for example, a ticket services module (e.g., a shared service that may or may not be used by other storage devices like flash).
