The lab designs hardware that runs cryptography securely and quickly.
AboutAbout the lab
Cryptography, in secure and fast hardware.
Ikeda Lab studies the design and evaluation of new high-performance cryptographic hardware using VLSI design techniques.
The lab aims to put high-performance cryptography, such as post-quantum cryptography and homomorphic encryption, into practical use as hardware that runs it securely and quickly.
It also works on evaluating the security of cryptographic hardware, for example whether secret information leaks when the hardware is attacked.
The lab also studies technology that automatically generates hardware from programs written in Python or C/C++, as well as image sensors.
Key terms
- VLSI
- Very-large-scale integration. An electronic circuit that packs a very large number of transistors onto a single chip.
- Post-quantum cryptography
- Cryptography designed so that it cannot be broken even if quantum computers become reality in the future.
- Homomorphic encryption
- Cryptography that allows computations such as addition and multiplication to be performed on data while it remains encrypted.

ResearchResearch themes
The lab uses VLSI design techniques to study the design and evaluation of new high-performance cryptographic hardware, as well as automatic hardware design technology. It evaluates not only how fast the hardware runs cryptography, but also how secure it is when attacked.
*Illustrative imageImplementing Post-Quantum Cryptography
The lab builds hardware that quickly performs key exchange (key encapsulation) and digital signatures for cryptography that stays secure even once quantum computers become reality, and evaluates its security as well.
*Illustrative imageNeural Networks and Security
The lab studies how to realize spiking neural networks (SNNs), which run on very little energy, without losing accuracy. It also studies TFHE, a cryptosystem that can compute on data while it remains encrypted.
*Illustrative imageImplementing Secret Sharing Computation
The lab implements hardware suited to multiparty computation, in which multiple participants jointly compute a result while keeping their own inputs secret.
*Illustrative imageQuantum-Resistant Logic Locking
Logic locking is a technique that protects the intellectual property and security of integrated circuits. The lab studies logic locking schemes that are hard to break even for quantum computers.
