On Enhancements Of Physical Layer Secret Key Generation And Its Application In Wireless Communication Systems, Kang Liu

Electronic Thesis and Dissertation Repository

As an alternative and appealing approach to providing information security in wireless communication systems, secret key generation at physical layer has demonstrated its potential in terms of efficiency and reliability over traditional cryptographic methods. Without the necessity of a management centre for key distribution or reliance on computational complexity, physical layer key generation protocols enable two wireless entities to extract identical and dynamic keys from the randomness of the wireless channels associated with them.

In this thesis, the reliability of secret key generation at the physical layer is examined in practical wireless channels with imperfect channel state information (CSI). Theoretical …

A Biopsychological Foundation For Linguistics, Jonathan J. Life

Electronic Thesis and Dissertation Repository

In this dissertation, I defend the view that natural languages are concrete biopsychological phenomena to be studied empirically. In Section One, I begin with an historical explanation. Some analytic philosophers, I argue, misapply formal logic as an analysis of natural language, when it was in fact originally developed as an alternative to natural language, employed for scientific purposes. Abstract, quasi-mathematical philosophies of language, I argue, are partially a result of this misunderstanding. I respond to Jerrold Katz’ argument that a proper understanding of analytic truth requires this quasi-mathematical philosophy of language through a model-theoretical analysis of analytic truth in modal …
