Xiphera brings together expertise in cryptography, secure applications, and electronics.

Xiphera is a privately held company based in and operating under the jurisdiction of Finland.



Matti Tommiska

CEO, Co-Founder

Matti is an electronics professional with 10 years of academic career followed by 13 years of expertise in international semiconductor business. During his industry career he has worked for Spansion, Altera, and Intel in both technical and sales roles. He has significant experience of the semiconductor market, customer applications and the security challenges they face.

Matti holds a doctoral degree in electrical engineering from Helsinki University of Technology (2005).

One of Matti's hobbies since childhood has been chess, and his favorite openings include King's Gambit when playing white, and King's Indian Defence when playing black.


Kimmo Järvinen

CTO, Co-Founder

Kimmo is a hardware cryptography engineer and researcher with more than 15 years of expertise. He has had academic research positions both in Finland (Aalto University and University of Helsinki) and Belgium (KU Leuven). His main expertise is designing FPGA-based secure and efficient coprocessors for modern cryptographic algorithms. He has authored more than 50 scientific publications about cryptography, cryptographic engineering, and secure embedded systems.

Kimmo holds a doctoral degree in electrical engineering from Helsinki University of Technology (2008).

Kimmo likes to spend his free time by taking photos with his camera. Some examples of Kimmo's pictures be seen on this website.


Xiphera's products and solutions have wide applicability in different end markets, where the customers' threat model and performance requirements vary considerably.


The communications market has a major focus on power consumption and performance measured as the achieved linerate in gigabits per second (Gbps).

Typical applications include both look-aside acceleration and inline acceleration of symmetric encryption at 10, 25, or 40 Gbps.

These linerates are an excellent fit for Intellectual Property (IP) cores running on FPGAs, since their performance, power consumption and resource requirements clearly outperform software-based implementations.

Xiphera offers high-speed versions of IP cores targeting the performance requirements of demanding communications applications..


Internet of Things (IoT) and Industry 4.0 offer new business opportunities for traditional control and automation companies, but an absolute requirement is comprehensive end-to-end security from industrial end points (sensors, actuators, etc.) to the cloud.

High-level security goals are relatively easy to formulate, but translating these goals to concrete cryptographic implementations is an underestimated challenge.

Additional challenges include diverse platforms and hardware architectures, and lack of international security standards targeting the industrial market.

Xiphera offers compact versions of IP cores targeting the resource and performance requirements of industrial applications.>.

An FPGA-based security solution also enables the customers to standardize on a flexible and scalable platform with a long lifetime.

Critical infrastructure:

The critical infrastructure (for example, governmental communications, utilities companies, military applications) market have the most advanced threat models, and in certain cases the emerging quantum computing technology has to be taken into account when designing secure systems.

An FPGA-based implementation of security typically achieves a higher National Security Accreditation Authority (NCSA) Protection Level than a software-based solution, and another advantage for FPGAs is the relative ease of achieving red/black separation.

All Xiphera IP blocks execute in constant time making them resistant to timing side-channel attacks, and the integrated TRNG (True Random Number Generator) removes the need for an external TRNG chip, thus reducing the attack surface.
