Description
Information flow control regulates where information is allowed to travel within an information system and between information systems (as opposed to who is allowed to access the information) and without explicit regard to subsequent accesses to the information. When data is encrypted, mechanisms designed to examine data content to detect attacks or malicious code are unable to accomplish this task unless they are capable of unencrypting the data.
