System and method for matching a pattern are provided. The pattern matching method includes performing a sub pattern matching operation to match at least one sub data of a plurality of sub data of a target data with a pre-stored pattern data, and performing a full pattern matching operation to determine whether the target data is identical to at least the pre-stored pattern data by referring to a result of the sub pattern matching operation, and wherein the full pattern matching operation is performed or not performed according to a type of the pre-stored pattern data. Accordingly, an accurate matching operation is performed with respect to the target data of various patterns.

System and method for matching pattern

Provided are an anti-malware system, and an operating method thereof. The anti-malware system matches an filtering operation on first target data to be filtered with a rule pattern, performs a filtering operation on the first target data according to a matching result, matches second target data to be malware-scanned with a malware pattern, and performs a malware scanning operation on the second target data according to a matching result, wherein the filtering operation and the scanning operation are performed on a system-on-chip (SoC).

Anti-malware system and operating method thereof

Provided is a pattern matching engine. The pattern matching engine calculates an error detection sign of target data and compares the calculated error detection sign with an error detection sign of a malware pattern DB. When the error detection sign of the target data and the error detection sign of the malware pattern DB are identical to each other, the pattern matching engine compares the target data with the malware pattern.

Pattern matching engine, terminal apparatus using the same, and method thereof

A system-on-chip (SOC) for semiconductor intellectual property (IP), a device including the same, and a method of operating the same are provided. The SOC includes: an interface which receives scanning data from a main module in which the SOC is mounted; and an anti-virus engine which determines whether a virus exists in the received scanning data. Accordingly, the security of a device is tightened.

SOC with security function and device and scanning method using the same

A smart card installed in a device receives from the device data to be scanned and determines whether a virus exists in the data. Accordingly, security of the device may be enhanced without using substantial resources of the device.

Smart card, anti-virus system and scanning method using the same

A device in which a system-on-chip (SOC) providing an anti-malware service is mounted and a method of performing the anti-malware service are provided. The device includes: a storage unit which stores a function library which is a collection of operations provided for use in the SOC providing the anti-malware service; and a scanning data sender which forms SOC transmission data with data to be scanned for viruses by calling at least one of the operations, and transmits the SOC transmission data to the SOC. Accordingly, a mobile device scans files for viruses and filters packets at a high speed.

Device and method for providing SOC-based anti-malware service, and interface method

An anti-virus protection system and method including receiving an address of a data server from a user, writing and transmitting a request message including the address received from the user, receiving the data from the data server, and determining whether the data contains malignant virus. Thus, a malignant web site is scanned/filtered by minimally using a restrictive memory and central process unit (CPU) resource of a mobile device, and a user uses a mobile device whose security is ensured even through a user moves to another country.

Anti-virus protection system and method thereof

Provided is a device including a chip that includes a firewall engine, and a driver, wherein the driver identifies an owner process of a packet to be transmitted, and transmits the packet to the chip only if the owner process is allowed to transmit the packet to an external device, wherein the chip performs filtering by applying a rule for packet filtering to the packet received from the driver.

SOC-based device for packet filtering and packet filtering method thereof

An efficient virus detection, malware detection, and packet filtering system in a mobile device by providing optimized hash functions from a server to a mobile device that reduce hash collisions during the virus detection, malware detection, and packet filtering in a system-on-chip configuration.

Anti-malware device, server, and method of matching malware patterns

An anti-malware device and an operating method thereof are provided. The operating method includes: filtering by a first logic unit of the processor, input data based on a rule; and scanning by a second logic unit of the processor, for malware in the data, the filtering and the scanning being performed at the same time. Accordingly, the security of the packet data is tightened.
