System to secure cryptographic keys and codes for data protection

IBM today announced that its engineers have been granted a patent on an approach for utilizing the inherent structure of a printed circuit board (PCB) to protect cryptographic keys and codes in a manner that is designed to be highly tamper-resistant. The patented system does not require extensive use of resin or other materials to encase a module or package containing keys and codes, thereby providing the opportunity for significant improvement in manufacturing yield, as well as a decrease in re
