Resumen
Fully homomorphic encryption allows computation to be performed on encrypted data without knowing or learning the decryption key. Therefore this technology can be extremely useful for storing and processing personal data. Due to the great interest in this technology, many software tools and libraries are now known to support fully homomorphic encryption. However, this field of cryptography is still relatively young. Standards and guidelines for using fully homomorphic encryption schemes are still under development. Thus, when using these libraries, it is necessary to pay attention to the cryptographic strength of the used schemes to avoid significant information security risks. We consider the issues of the practical application of fully homomorphic encryption schemes, including the choice of suitable libraries and their initialization parameters to ensure a sufficient security level.
