| Abstract |
In order to take a proactive approach to security incidents such as information exposure and illegal counterfeiting caused by recent complex and sophisticated cyber attacks, it is important for companies and individuals to use secure devices without security vulnerabilities. In fact, IMA(Integrity Measurement Technology) technology, which guarantees that the executable file is not forged at run-time, has been used to prevent the threat of data leakage from malicious code infiltrating the user's mobile device. In addition, to enhance device security, TrustZone-based Integrity Measurement Architecture (TIMA), which provides integrity based on hardware such as Secure Boot and TrustZone, has been used. In this paper, I propose the TPM-IMA technology that provides the run-time integrity of the kernel and executable files by using a hardware security chip called TPM (Trusted Platform Module) instead of TrustZone. The proposed technology has the advantage of providing executable file integrity as well as without hardware changes to support the TrustZone to products that have already been released with TPM. |
