Fully Homomorphic Encryption
Fully Homomorphic Encryption (FHE) is a cryptographic technique that allows computations to be performed directly on encrypted data without needing to decrypt it first. It enables secure data processing in untrusted environments, such as cloud servers, by preserving data privacy throughout the computation. This ensures that sensitive information remains confidential even while being analyzed or manipulated.
Developers should learn FHE when building applications that require privacy-preserving data analysis, such as in healthcare, finance, or secure cloud computing, where data must be processed without exposing it to third parties. It is particularly useful for scenarios like encrypted database queries, secure machine learning on sensitive datasets, and compliance with strict data protection regulations like GDPR or HIPAA.
