چکیده
Answer: Long-term storage of keys, specially in disk, must take into account handling of backups and possible direct access to the underlying media. Therefore, keys’ long term storage should take place in encrypted format. For instance, an administrative password may be used to encrypt the keys. Even better, keys could be encrypted using an administrative key that is physically protected in physically secured storage (such as a smartcard). Therefore, software should be programmed to handle encrypted key storage, not raw keys. (b) Discuss a security issue related to the handling of keys in memory. Do the same concerns apply to short-term values that should remain secret, such as session keys and/or nonces?
