This paper develops a framework for wireless security that provides confidentiality, identity authentication, message authentication, integrity, sender non-repudiation, receiver non-repudiation and anonymity. Our framework is based on two physical primitives: collaborative jamming and spatial signature enforcement. Notably, it eschews the use of shared secrets, while providing a cryptosystem that is no less secure than conventional cryptosystems.
