Synopsis:
With the recent advances of internet of things and digital communication, we see the needs for lightweight and secure cryptographic primitives in providing a secure channel for information exchange at large scale. However, the implementation of these cryptographic primitives in hardware platform presents several challenges in terms of throughput and power performance owing to the resource constraints on small devices.
In this talk, we present the algorithmic and architectural optimization techniques which are proposed to design lightweight encryption S-box digital circuits. To be precise, our work focuses on the circuit optimization of the most popular cryptographically function; the multiplicative inversion over binary finite field GF(2n). It is one of the most important computations in cryptography and is computationally intensive in nature.
The optimizations presented in this talk is important in hardware implementation of standard cryptographic algorithms such as the Advanced Encryption System (AES). The presentation shall include our novel designs of AES S-box, which are effective and efficient for hardware implementation. In addition to that, the proposed techniques are also applicable to other cryptographic ciphers. Therefore, the work is further extended to optimization in Elliptic Curve Cryptography (ECC).
