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

The article delves into the security analysis of a single-state circular mediated semi-quantum key distribution (CMSQKD) protocol, which allows two communicating users to establish secure keys with the help of a third-party server. It explores the protocol's resistance to attacks, including those by a potentially dishonest third-party server. The authors derive the key rate and establish a threshold for the error rate to ensure the protocol's security. Additionally, the article proposes a multiple-user CMSQKD protocol, expanding the number of users who can share secure keys. The paper concludes with a summary of the protocol's security and potential future work.
