Control System Data Integrity Using a Variable- Round Message Authentication Code with an Elliptic Curve Key Exchange Protocol

摘要

The challenge of securing industrial control systems is significant and previous work provided solutions to a number of these challenges including performing mathematical operations on BigIntegers; generating and distributing keys; generating cryptographically secure hash values; implementing random number generation; and ensuring that the operations can be performed without impacting normal operation / scan times. In previous works the Variable-round Message Authentication Code (VMAC) algorithm was introduced for per-message data authentication, and a scheme was presented for two nodes to exchange a symmetric key for VMAC.
