Data protection by detection of intrusion into electronic assemblies

摘要: The present invention provides an intrusion barrier for protecting against mechanical or chemical into electronic assembly, especially one containing volatile memory. It includes a screen material surrounding the assembly which has formed thereon fine conductive lines in close proximity to each other. are of particles dispersed solidified matrix looses its integrity when removed from screen. An electrical supply and signal detection circuit is provided generates output responsive given change resistance lines, such that if changes result attack, generated can cause erasure Also, preferably radiation temperature sensing circuits memory intensity below value.
