Analytical Approach of Trivium FPGA Implementations against Information Security Vulnerability

The focus of this work is addressing the issue of the information security along with to introduce faults in Trivium stream ciphers implemented on FPGA. Daily, an incredible amount of information is exchanging in many digital forms. The digital devices have become the data sources which pump out the majority of the information on the web. The evolution of the Internet of Things (IoT) has come up with innovative solutions and its demand for information security is indeed a challenging task to maintain the sensitive information integrity in an ensured way. The implementation of cryptographic algorithms in IoT provides lightweight solutions which are simpler in design. Trivium stream cipher is a cited example for IoT cryptographic lightweight initiative which is also a noted finalist of the eSTREAM project. The previous studies show that the cryptographic algorithms are regarded as vulnerable sources when it comes to hardware implementations. A simplified approach was proposed to study the vulnerability behavior field-programmable gate array (FPGA) implementations of Trivium stream ciphers against various attacks. A description of the system design alterations in the clock signal has provided. The Trivium cipher and their routing dependences are thoroughly tested with two different FPGA families to know the vulnerability and, the results show that all cases of Trivium cipher are vulnerable to fault attacks.
