Security in today's environment serves as a critical foundation across multiple domains. In digital systems, it has evolved from a specialized concern to a core necessity as organizations face sophisticated cyber threats amid expanding attack surfaces from cloud computing and IoT devices. For defense, security now encompasses protection against both conventional warfare and advanced cyber operations. At the individual level, security extends beyond physical safety to digital privacy and identity protection. In emerging technologies like 6G and AI, security has shifted from an afterthought to a fundamental design principle. The interconnected nature of global systems has transformed security into a collective responsibility requiring unprecedented cooperation between governments, corporations, and individuals to address cross-border threats. Some of the challenges that members of the laboratory are addressing are:
Physical layer security
Hardware security
AI for enhanced threat detection
Quantum communications
