Abstract We will discuss Integrated Circuit (IC) security and trust threats and corresponding countermeasures with a focus on wireless ICs. We will present solutions to protect RF transceiver ICs against piracy attempted by malicious System-on-Chip (SoC) integrators, foundries, or end-users via reverse-engineering. We will also present hardware Trojan attacks on RF transceivers aiming at creating a covert channel for stealing sensitive information, i.e., cypher keys. Brief Biography Haralampos-G.

Mohamed L. Barakat, et al., "Hardware realization of chaos based block cipher for image encryption." In ICM 2011 Proceeding, 2011, 1. Unlike stream ciphers, block ciphers are very essential for parallel processing applications. In this paper, the first hardware realization of chaotic-based block cipher is proposed for image encryption applications. The proposed system is tested for known cryptanalysis attacks and for different block sizes. When implemented on Virtex-IV, system performance showed high throughput and utilized small area. Passing successfully in all tests, our system proved to be
