Abstract
The present invention is directed to a distributed architecture of an information handling system, including a buried nucleus inaccessible for inspection without heroic means while the buried nucleus is in operation, and a trusted authority for generating a secure protocol. The secure protocol controls the operation of the buried nucleus.
Claims3
A method for protecting encrypted information, comprising steps of:
- (a) setting a buried nucleus in a quasi-stable mode of operation, including:
- (a1) delivering a key through a secure protocol to said buried nucleus;
- (a2) setting up a bit string by said key;
- and (a3) giving a set of timer banks a pseudorandom temporal variability by said bit string;
- (b) stopping clocking when said buried nucleus deviates from said quasi-stable mode;
- (c) rebuilding a secure environment within said buried nucleus after an intrusion is detected;
- and (d) resetting an attack associated with said detected intrusion to zero when replication of re-buildup by an attacker is detected.

An apparatus for protecting encrypted information, comprising:
- (a) means for setting a buried nucleus in a quasi-stable mode of operation, including:
- (a1) means for delivering a key through a secure protocol to said buried nucleus;
- (a2) means for setting up a bit string by said key;
- and (a3) means for giving a set of timer banks a pseudorandom temporal variability by said bit string;
- (b) means for stopping clocking when said buried nucleus deviates from said quasi-stable mode;
- (c) means for rebuilding a secure environment within said buried nucleus after an intrusion is detected;
- and (d) means for resetting an attack effort associated with said detected intrusion to zero when replication of re-buildup by an attacker is detected.

A non-transitory computer-readable medium having computer-executable instructions for performing a method comprising steps of:
- (a) setting a buried nucleus in a quasi-stable mode of operation, including:
- (a1) delivering a key through a secure protocol to said buried nucleus;
- (a2) setting up a bit string by said key;
- and (a3) giving a set of timer banks a pseudorandom temporal variability by said bit string;
- (b) stopping clocking when said buried nucleus deviates from said quasi-stable mode;
- (c) rebuilding a secure environment within said buried nucleus after an intrusion is detected;
- and (d) resetting an attack effort associated with said detected intrusion to zero when replication of re-buildup by an attacker is detected.
