	abstract = {Medical information is extremely sensitive in nature  a compromise, such as eavesdropping or tampering by a malicious third party, may result in identity theft, incorrect diagnosis and treatment, and even death. Therefore, it is important to secure the transfer of the medical information from its source, i.e., the patient, to the system that collects and records it or its technology adoption will face a strong resistance from the users. We consider the scenario where a patient has a portable, wireless medical device that transfers the medical information to a remote server. We decompose this problem into two sub-problems and propose security solutions to each of them: (a) to secure the link between the patient and the portable device, and (b) to secure the link between the portable device and the network. Thus, we push the limits of the network security to the cutting edge: authenticating the user using their biometric information, authenticating the device to the network at the physical layer, and strengthening the security of the wireless link with a key exchange mechanism. The proposed authentication methods can be used for recording the readings of medical data in a central database and for accessing medical records.},

	abstract = {Physical layer authentication techniques exploit signal characteristics to identify radios. We describe how multicarrier systems may use such techniques to stealthily authenticate while maintaining high levels of security and robustness. We show that with channel state information (CSI) at the transmitter and receiver, multicarrier authentication systems can further improve performance by carefully allocating the authentication power on each carrier.},

	abstract = {Authentication is the process where claims of identity are verified. Though authentication mechanisms typically exist above the physical layer, physical layer methods have recently been introduced that do not require extra bandwidth. In this paper, we propose a multi-carrier extension to the work and consider the stealth and robustness tradeoffs. We conclude by discussing the power-reliability tradeoff and the applicability to cross-layer security.},

	abstract = {Authentication is the process where claims of identity are verified. Most mechanisms of authentication (e.g., digital signatures and certificates) exist above the physical layer, though some (e.g., spread-spectrum communications) exist at the physical layer
often with an additional cost in bandwidth. This paper introduces a general analysis and design framework for authentication at the
physical layer where the authentication information is transmitted concurrently with the data. By superimposing a carefully designed secret modulation on the waveforms, authentication is added to the signal without requiring additional bandwidth, as do spread-spectrum methods. The authentication is designed to be stealthy to the uninformed user, robust to interference, and secure for identity verification. The tradeoffs between these three goals are identified and analyzed in block fading channels. The use of the authentication for channel estimation is also considered, and an improved bit-error rate is demonstrated for time-varying channels. Finally, simulation results are given that demonstrate the potential application of this authentication technique.},
