Patents

Research-based solutions are patented at international level and are used with great success in a wide range of projects.

FHE solution
(fully homomorphic
encryption)

certSIGN, a Romanian company specialized in encryption solutions, has obtained an invention patent for a homomorphic data encryption method that allows data to be processed without the need to decrypt it. The patent was granted by the Patent and Trademark Office of the United States of America and has the number US10454668 of October 22, 2019.

Unlike classic encryption solutions, where data to be processed is first decrypted, then analyzed and processed and in the end re-encrypted, a process that can give rise to security breaches, with homomorphic encryption the data remains encrypted throughout the processing.

Why our homomorphic encryption solution?

In recent years, cloud encrypted data storage has become a widely adopted business standard by companies and is a secure storage solution. However, security breaches occur when it is necessary to access data for a simple search or for a broader analysis. Normally, in such situations the data is decrypted to perform the required search or analysis, thus creating the opportunity for information theft.

With the homomorphic encryption, the data remains encrypted and is protected at all times, and the element that allows it to remain confidential and secure, even if a third party uses it, is a mathematical system for analyzing and processing encrypted data.

Based on the patent obtained, we developed certFHE.

Differentiators

Our solution uses new and more secure encryption methods based on cryptographic algorithms, which do not require additional investment in IT infrastructure, and which reduce data processing time.

Users

Homomorphic encryption can be successfully implemented in organizations, mainly in areas where the confidentiality of customers’ personal data is crucial – finances, banking health, insurance, etc.

Briefly

Obtaining the patent took 4 years, involving a team of specialists in cryptography, PKI and cybersecurity and being the result of a continuous effort of investment and involvement in research activities in cryptography.
