Tamper Protection for Security Devices
2008 Bio-inspired, Learning and Intelligent Systems for Security, 2008Organic electronic materials are proposed to be used as a tamper protection grid for hardware security modules. Methods of designing a protection grid likely to be damaged in currently published depackaging techniques are derived. Organic protection layers are shown to be a feasible method of protecting hardware security modules against tampering.
