Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

This article introduces a Non-Time-Limited (NTL) channel sounding protocol designed to generate secure keys in wireless communications, addressing the limitations of current methods that rely on stringent conditions such as channel reciprocity and communication delay. The NTL protocol leverages wireless channel characteristics to generate high-speed, consistent security keys, ensuring absolute security in Shannon’s theory. The article compares the NTL protocol with existing methods, highlighting its advantages in high-speed mobile communications, underwater acoustic communications, and its potential for long-distance communication through relay nodes. Additionally, the authors propose a relay-assisted secret extension mechanism to enhance defense against collaborative eavesdropping. The paper concludes with simulation results demonstrating the superior performance of the NTL protocol in various communication scenarios, making it a promising solution for secure key generation in wireless networks.
