Homomorphic Encryption

Published:

Homomorphic encryption allows computations to be performed on data while it remains encrypted. Instead of decrypting the data first, the system operates directly on the encrypted values. The output is produced in encrypted form as well, and only the data owner can decrypt it to reveal the correct final result. This keeps sensitive values hidden throughout processing.

This is useful when data needs to be processed outside the owner’s environment, such as in cloud services or shared infrastructure. Homomorphic encryption enables analytics or model inference while keeping the underlying inputs private, which supports workflows where confidentiality must be preserved end to end.
