Abstract
Embodiments of the present disclosure provide a method, an apparatus, and a system for authenticating a fully homomorphic message, where the method includes: acquiring a message authentication key, where: the message authentication key includes a public key, a first character string, and a second character string; the first character string is a character string that consists of 0 and 1 and has a length of n; the second character string is a character string that consists of 0 and 1 and has a length of n; generating an authentication fingerprint corresponding to each bit of to-be-computed data; sending a computation request to a server; receiving an authentication fingerprint corresponding to the computation result; and performing correctness authentication on the computation result according to the received authentication fingerprint, which effectively reduces an amount of computation in a verification process.
