Our story

The two co-founders of Xiphera, Matti Tommiska and Kimmo Järvinen, first worked together in an academic cryptographic project for a few years in the beginning of 2000’s. In 2016, they started to seriously discuss the widening gap between the strong theoretical foundation of cryptography and the often imperfect implementations of cryptography in mission critical systems.

Their conclusion was clear: Everyone deserves security, but designing secure systems is not for everyone. Security is fundamentally based on cryptography, and a flawless implementation of cryptography is an absolute requirement for secure systems. Software-based implementations of cryptography inherently have more potential weaknesses than a hardware-based implementation. This observation crystallised the underlying potential for a new company, and Xiphera, Ltd, was founded in July, 2017.

Since then, we have grown organically in international markets, investing in further product development as well as widening the global partnership network. The number of employees has increased in both technical and commercial roles, still letting us to retain the nimbleness of a growth company.

Cryptography should never be considered stagnant, and we will follow the industry development and proactively react to and support new innovations and changes in standards and algorithms. Our ambition is to continue organic and profitable growth, explore new target market possibilities, and become a world-recognized expert and leader in hardware-based security and cryptography.

Target markets

Xiphera’s products and solutions have applications in various markets, where the customers’ security needs, threat model, and performance requirements vary. Depending on the use case, the focus can be either on high performance, optimised resource use, or a balanced combination of the two.


Security has for a long time been an important factor in network design. The ongoing adoption of 5G technology further increases the need to properly plan and design security solutions into communications networks.

In addition to security, the communications market has a major focus on power consumption and performance measured as the achieved line rate in gigabits per second (Gbps). Example applications include both look-aside and inline acceleration of symmetric encryption at 10, 25, or 40 Gbps.

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

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

Industrial automation

Internet of Things (IoT) and Industry 4.0 offer new business opportunities for traditional control and automation companies, but an absolute requirement for the business case to materialise 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 into 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, and a hardware-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 many cases quantum computing technology has to be taken into account when designing secure systems.

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

All Xiphera’s 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.
