Picture of me

My name is Estuardo and I am a cryptographer at Xiphera in Finland, where we design and implement cryptographic solutions in hardware. I received my PhD at Aalto University under the supervision of Chris Brzuska, co-advised by Wil Michiels. During my PhD, I worked on definitional studies and feasibility results for white-box cryptography, as well as on the design of automated attacks on white-box cryptographic implementations. Later, I held different research positions at Aalto and Radboud University, working on hardware security as well as side-channel analysis of lattice-based crypto candidates. In earlier years, I was an employee at the Leibniz Institute for High Performance Microelectronics IHP, where I worked on the design and implementation of hardware accelerators for elliptic curve cryptography in the light of side channel analysis attacks.

I've always been curious about the challenges that come up when cryptography is implemented in the real world.

Below you will find a list of my publications and further research activities from recent years.
