CORE DEFINITION

A form of encryption that allows computations to be performed on ciphertext, and the result, when decrypted, matches the result of performing the same operations on plaintext. That is, "data can be used but not seen."

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Decoupling trust and privacy. In collaboration, you don't have to expose your hand (raw data) to get help (computing power) from others. This provides a theoretical basis for "zero-trust collaboration."

Anchor fast decisions

Homomorphic encryption allows direct computation on ciphertext, and the result, when decrypted, is consistent with plaintext computation, thereby achieving usability without visibility.
