TASO: Jailbreak LLMs Via Alternative Template and Suffix Optimization

Many recent studies showed that LLMs are vulnerable to jailbreak attacks, where an attacker can perturb the input of an LLM to induce it to generate an output for a harmful question. In general, existing jailbreak techniques either optimize a semantic template intended to induce the LLM to produc...

Encoded Jamming Secure Communication for RIS-Assisted and ISAC Systems

This paper considers a cooperative jamming CJ-aided secure wireless communication system. Conventionally, the jammer transmits Gaussian noise GN to enhance security; however, the GN scheme also degrades the legitimate receiver's performance. Encoded jamming EJ mitigates this interference but does...

CovertAuth: Joint Covert Communication and Authentication in MmWave Systems

Beam alignment BA is a crucial process in millimeter-wave mmWave communications, enabling precise directional transmission and efficient link establishment. However, due to characteristics like omnidirectional exposure and the broadcast nature of the BA phase, it is particularly vulnerable to...
