Post-quantum cryptography is an innovative approach to data protection based on the fundamental laws of quantum physics.
Why was there a need for post-quantum cryptography?
Quantum computers
Powerful quantum machines will be able to crack traditional cryptographic keys in minutes, which would take classical computers billions of years to do. This threatens the privacy of financial transactions, correspondence and user data
Storing data «for the future»
Even if a quantum computer hack has not yet occurred, attackers can already intercept and store encrypted data today. In the future, when quantum computers become more accessible, they could decrypt these archives, revealing sensitive information
Critical infrastructure threats
Banks, government agencies, medical and energy systems are particularly vulnerable to new threats. Without defenses adapted to the quantum era, they become easy targets for attacks
For whom is post-quantum cryptography useful?
The use of post-quantum cryptography is becoming a necessity for those who seek to stay one step ahead of cyber threats and guarantee the security of their information in the face of advances in quantum technologies
Financial organizations and banks
Government and defense agencies
Healthcare companies
Law Firms
Telecommunication companies
IT companies and software developers
Combining homomorphic encryption (FHE) and Shamir's secret sharing scheme represents our innovative solution for storing and handling data using post-quantum security.

Secret partitioning
The secret is represented as a free term polynomial of degree \( t-1 \), where \( t \) is the minimum number of fractions required to recover the secret. Random coefficients for the polynomial are generated and the values of the polynomial at various points are calculated, forming the shares of the secret
Encrypting the fractions
Each fraction is encrypted using homomorphic encryption, which allows us to perform computations on the encrypted data without decrypting it
Distribution of encrypted shares
The encrypted shares are distributed to the respective participants
Secret recovery
When \( t \) participants combine their encrypted shares, the server performs homomorphic operations to interpolate the polynomial and recover the secret in encrypted form. The resulting encrypted secret is sent to the participants, who can decrypt it by retrieving the original secret
Advantages of this approach:
Data security
The secret remains encrypted throughout the process, reducing the risk of compromise.
Flexibility
Allows the secret to be recovered securely, provided that the minimum required number of participants have provided their shares.
Applicability
Suitable for scenarios where privacy-preserving data sharing is required, such as in distributed systems or when dealing with sensitive information.
The combination of homomorphic encryption and Shamir’s secret sharing scheme is an efficient method to protect and recover secret information in collaborative computing environments.
