What is the experimental technology that might lead to the possibility of processing encrypted data without having to decrypt it first?
Homomorphic encryption is an experimental technology that allows for the processing of encrypted data without having to decrypt it first. This cryptographic technique enables computations to be performed on ciphertext, generating an encrypted result that, when decrypted, matches the result of operations performed on the plaintext. This technology holds promise for secure data processing, especially in scenarios requiring privacy-preserving computations.
C. Homomorphic encryption
The experimental technology that might lead to the possibility of processing encrypted data without having to decrypt it first is homomorphic encryption. This is a cryptographic technique that allows computations to be performed on encrypted data without requiring decryption. It has three types, depending on how the encryption approach is designed: partially homomorphic encryption (PHE), somewhat homomorphic encryption (SHE), and fully homomorphic encryption (FHE). FHE is the type emerging as a solution provided by large service providers and is the target of intense continuous research that currently focuses on using FHE to enable safe big data machine learning. Homomorphic encryption is far from mainstream due to performance challenges, requiring more processing power than most organizations can afford or manage.
