Publication number: 20140317381Abstract: Disclosed is a method of operating an immediate value in an extendable instruction set computer (EISC) processor, comprising: checking whether or not an unsigned immediate value is used to generate an extension register (ER) value for operating an immediate value; and generating the ER value by performing zero extension for the unsigned immediate value using an unsigned load extension register with immediate (ULERI) instruction if the unsigned immediate value is used. It is possible to improve operational efficiency by preventing an LERI instruction from being unnecessarily executed when an immediate value is operated using a 16-bit instruction in the EISC processor.Type: ApplicationFiled: April 30, 2013Publication date: October 23, 2014Applicants: Foundation for Research & Business, Seoul National University Of Science & Technology, Korea University Research and Business Foundation, Advanced Digital Chips Inc.Inventors: Seung Eun Lee, Yeong Seob Jeong, Sang Don Kim, Taeweon Suh, Han Yee Kim, Young Ho Cha, Kwan Young Kim

Patent number: 8800036Abstract: The input characteristics of a real-time IDS change continuously with time therefore setting a rigid (time and behavior invariant) classification threshold limits the accuracy that the IDS can potentially achieve. A generic threshold tuning method and system is proposed which can adaptively tune the detection threshold of a real-time IDS in accordance with varying host and network behavior. The method and system perform statistical and information-theoretic analysis of network and host-based IDSs' anomaly based intrusions to reveal a consistent time correlation structure between benign activity periods which is used to predict future anomaly scores and to adapt an IDS' detection threshold accordingly.Type: GrantFiled: January 22, 2010Date of Patent: August 5, 2014Assignee: The School of Electrical Engineering and Computer Science (SEECS), National University of Sciences and Technology (NUST)Inventors: Syed Ali Khayam, Muhammad Qasim Ali
