SECURE MEANS FOR GENERATING A SPECIFIC KEY FROM UNRELATED PARAMETERS |
摘要 |
A technique and method for improving the security of the usage of a key in devices or systems with modes of operation that must be secured whereby the key has multiple fields with timing information that must be matched to transitions of a randomly generated clock, the randomly generated clock derived from a fixed frequency clock, whereby tampering of the fixed frequency clock will result in detection of the security attack and exit from the secure mode of operation.
