Abstract: Importing of mobile devices and usage of open source operating system/software makes mobile devices more prone to malwares. Vulnerabilities in hardware such as hardware Trojans cannot be detected and hence opens a high security gap. In order to tackle the hardware and software vulnerabilities in mobile devices, a new hardware platform should be introduced. The paper proposes a hardware technology for mobile devices that can create custom hardware on the device. The custom hardware is encrypted at logic level in order avoid all hardware/software threats. Only the applications with appropriate decryption code embedded can alone unlock the hardware and can execute. The security property is analysed using mathematical modelling and found that there is increase in 10% security index during each step of security addition compared to related works.

Keywords: mobile devices; hardware platform; logic encryption; key gates; custom hardware.
