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

SDN-API-Sec-Fast is a blockchain-based authorization system designed to enhance the performance and security of cross-domain Software-Defined Networks (SDNs). This article explores the architecture of SDN-API-Sec-Fast, which includes a read-only mode and conflict detection mechanisms to ensure efficient and conflict-free access control. The system employs a consortium blockchain to provide a decentralized and transparent authorization process, addressing the scalability and single point of failure issues inherent in traditional centralized approaches. The article delves into the security analysis of SDN-API-Sec-Fast, examining its resilience against various attacks such as spoofing, replay, and privilege escalation. Experimental results demonstrate the system's performance in terms of latency and throughput, comparing it with existing solutions like SDN-API-Sec and B-DAC. The proof-of-concept implementation showcases the practical applicability of SDN-API-Sec-Fast, highlighting its potential as a promising solution for secure and efficient cross-domain SDN environments.
