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

摘要

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.

1. A system-on-chip (SOC) for semiconductor intellectual property (IP), which is configured to be mounted on a mobile device, the SOC comprising:
a central processing unit (CPU); an interface which receives scanning data from the mobile device; a communication unit which receives signature data encrypted with a session key generated by the SOC; a firewall which performs a filtering operation with respect to the encrypted signature data; a decryption unit which decrypts the encrypted signature data; a storage unit which stores the decrypted signature data; and an anti-virus engine which determines whether a virus exists in the scanning data using the decrypted signature data, wherein the filtering operation performed by the firewall comprises (i) determining a source and a destination of the encrypted signature data and (ii) determining whether to block the encrypted signature data or pass the encrypted signature data through the firewall based on a predetermined filtering policy, the determined source, and the determined destination, and wherein the decryption unit decrypts the encrypted signature data only in response to the encrypted signature data passing through the firewall according to the filtering operation.
