Abstract
An arrangement for the protection of cryptographic keys and codes from being compromised by external tampering, wherein the arrangement is utilized within a multilayered securing structure. More particularly, there is provided a multilayered securing structure for the protection of cryptographic keys and codes, which may be subject to potential tampering when employed in computers and/or telecommunication systems. A method is provided for producing such multilayered securing structures within a modular substrate with the intent to protect cryptographic keys and codes which are employed in computers and/or telecommunication systems from the dangers of potential tampering or unauthorized access.
