The impact of microarchitectural attacks in Personal Computers (PCs) can be further adapted to and observed in internetworked All Programmable System-on-Chip (AP SoC) platforms. This effort involves the access control or execution of Intellectual Property cores in the FPGA of an AP SoC Victim internetworked with an AP SoC Attacker via Internet Protocol (IP). Three conceptions of attacks were implemented: buffer overflow attack at the stack, return-oriented programming attack, and command-injection-based attack for dynamic reconfiguration in the FPGA. Indeed, a specific preventive countermeasure for each attack is proposed. The functionality of the countermeasures mainly comprises adapted words addition (stack protection) for the first and second attacks and multiple encryption for the third attack. In conclusion, the recommended countermeasures are realizable to counteract the implemented attacks.

Cryptographic protocols and algorithms are the strength of digital era in which we are living. Unluckily, the security of many confidential information and credentials has been compromised due to ignorance of required security services. As a result, various attacks have been introduced by talented attackers and many security issues like as financial loss, violations of personal privacy, and security threats to democracy. This research paper provides the secure design and architecture of cryptographic protocols and expedites the authentication of cryptographic system. Designing and developing a secure cryptographic system is like a game in which designer or developer tries to maintain the security while attacker tries to penetrate the security features to perform successful attack.
