2017. A red team blue team approach towards a secure processor design with hardware shadow stack. 2017 IEEE 2nd International Verification and Security Workshop (IVSW). :57–62.
Software attacks are commonly performed against embedded systems in order to access private data or to run restricted services. In this work, we demonstrate some vulnerabilities of commonly use processor which can be leveraged by hackers to attack a system. The targeted devices are based on open processor architectures OpenRISC and RISC-V. Several software exploits are discussed and demonstrated while a hardware countermeasure is proposed and validated on OpenRISC against Return Oriented Programming attack.
