WO2010117154A3 - System-on-a-chip malicious code detection apparatus, and application-specific integrated circuit, for a mobile device - Google Patents

Abstract

The present invention relates to a technique for configuring system-on-a-chip and application-specific integrated circuit (ASIC)-based hardware for detecting malicious code intruding on a mobile device. The aim of present invention is accomplished by a system-on-a-chip, comprising: a hardware-based firewall which performs a packet-filtering process on the packet received from an external source via a media access control unit in accordance with the firewall setting established by a firewall set unit on a memory for system-on-a-chip, and stores the result of the packet-filtering process in a memory for application, or transmits the result of the packet-filtering process to an antimalware engine; a hardware-based antimalware engine which performs a pattern-matching process among the code patterns in the file transmitted from the firewall or the file received via an input/output interface unit with the patterns of the malicious code registered in a malware signature database on the memory for system-on-a-chip provided in the system-on-a-chip, to detect malicious code; said memory for system—on-a-chip, which provides the firewall settings, and contains the malware signature database; and a hardware-based controller which controls switching operations to transmit the file filtered by the firewall directly to the memory for application, or to the antimalware engine, and controls the malicious code detection cycle of the antimalware engine.
