Improving the performance of authentication protocols using efficient modular multi exponential technique.

Efficient and secure authentication of the user in today's world, where most of the multimedia data is shared over the public network, is essential. The verification step of the multi-user applications like OTT(over-the-top) platforms has modular-multi exponentiation(MME) as its vital operation. This article presents an efficient MME which uses Multiplication and Forwarding technique (MFW). MFW technique efficiently computes the MME and also avoids side-channel attacks (SCAs) using the integrated multi-level confusion mechanisms. Mostly, SCAs are secured by hardware means only. This article presents a novel algorithmic way of counteracting the SCAs. The proposed technique is more efficient (efficiency 1.109) than the state-of-the-art. Another advantage of the designed MFW MME technique is that it is directly implementable in hardware. We have implemented the techniques on FPGA using Vivado 21.2 on Virtex-7 evaluation boards. The compatibility has also been verified using Cadence for ASIC. [ABSTRACT FROM AUTHOR]
