Rei Ueno
Kyoto University
Welcome to my homepage!
I am an associate professor at Kyoto University. My research interest includes implementation aspects of cryptography, hardware security, and secure computer architecture. In particular, I have been working for side-channel attacks on symmetric and public key cryptosystems (power/EM and cache analyses), secure and efficient cryptographic implementations, development of application-specific cryptographic schemes for secure computer architecture.
