“…It is important to remember that a cryptographic signature generated with an ECDSA algorithm having the size 64 bits has the same security level as an Rivest Shamir Adleman (RSA) cryptographic signature of size 2048 bits. In recent years, research on ECDSA hardware implementation has become very popular [1][2][3][4][5][6]. A lot of research is being done to improve ECDSA's performance and this has led to a large number of implementations.…”

“…A lot of research is being done to improve ECDSA's performance and this has led to a large number of implementations. In 2018, Asif et al [6] developed a new architectural design of the ECDSA algorithm, for intelligent transport system (ITS) applications, which is able to validate the constraints in real time. The authors employed parallel processing techniques to minimize hardware delays which reduces real-time security and end-to-end delay of ITS messages.…”

Since the end of the 1990s, cryptosystems implemented on smart cards have had to deal with two main categories of attacks: side-channel attacks and fault injection attacks. Countermeasures have been developed and validated against these two types of attacks, taking into account a well-defined attacker model. This work focuses on small vulnerabilities and countermeasures related to the Elliptic Curve Digital Signature Algorithm (ECDSA) algorithm. The work done in this paper focuses on protecting the ECDSA algorithm against fault-injection attacks. More precisely, we are interested in the countermeasures of scalar multiplication in the body of the elliptic curves to protect against attacks concerning only a few bits of secret may be sufficient to recover the private key. ECDSA can be implemented in different ways, in software or via dedicated hardware or a mix of both. Many different architectures are therefore possible to implement an ECDSA-based system. For this reason, this work focuses mainly on the hardware implementation of the digital signature ECDSA. In addition, the proposed ECDSA architecture with and without fault detection for the scalar multiplication have been implemented on Xilinx field programmable gate arrays (FPGA) platform (Virtex-5). Our implementation results have been compared and discussed. Our area, frequency, area overhead and frequency degradation have been compared and it is shown that the proposed architecture of ECDSA with fault detection for the scalar multiplication allows a trade-off between the hardware overhead and the security of the ECDSA.
