On Constructing Secure and Hardware-Efficient Invertible Mappings
Elena Dubrova
Our society becomes increasingly dependent on wireless communications. The tremendous growth in the number and type of wirelessly connected devices in a combination with the droppi…
Two Countermeasures Against Hardware Trojans Exploiting Non-Zero Aliasing Probability of BIST
Elena Dubrova, Mats Näslund, Gunnar Carlsson +2
The threat of hardware Trojans has been widely recognized by academia, industry, and government agencies. A Trojan can compromise security of a system in spite of cryptographic pro…
Ring Oscillator Physical Unclonable Function with Multi Level Supply Voltages
Shohreh Sharif Mansouri, Elena Dubrova
One of the most common types of Physical Unclonable Functions (PUFs) is the ring oscillator PUF (RO-PUF), in which the output bits are obtained by comparing the oscillation frequen…
Synthesis of Parallel Binary Machines
Elena Dubrova
Binary machines are a generalization of Feedback Shift Registers (FSRs) in which both, feedback and feedforward, connections are allowed and no chain connection between the registe…
Synthesis of Binary k-Stage Machines
Elena Dubrova
An algorithm for constructing a shortest binary k-stage machine generating a given binary sequence is presented. This algorithm can be considered as an extension of Berlekamp-Masse…
An Improved Implementation of Grain
Shohreh Sharif Mansouri, Elena Dubrova
A common approach to protect confidential information is to use a stream cipher which combines plain text bits with a pseudo-random bit sequence. Among the existing stream ciphers,…
