Embodiment 1
[0054] like figure 1As shown, Embodiment 1 of the present disclosure provides a location selection method for facilities based on encrypted location data. The Paillier homomorphic encryption scheme is used to encrypt the location data, and any encryption scheme with additive homomorphic properties can also be used instead.
[0055] The Paillier homomorphic encryption scheme is an additive homomorphic encryption scheme, which only supports the addition operation of ciphertext. However, in clustering calculations, multiplication and comparison operations are required, which are not supported by the Paillier homomorphic encryption scheme. This embodiment solves the above problems by introducing an independent auxiliary computing party and designing a corresponding secure computing protocol.
[0056] In this embodiment, the entities involved include: several location providers (clients), a cluster computing party (enterprises with equipment site selection requirements), and an au...
Embodiment 2
[0112] like figure 2 As shown, Embodiment 2 of the present disclosure provides a facility location selection system based on encrypted location data, multiple customers (location providing terminals), auxiliary computing party AS (first terminal) and cluster computing side S (second terminal ), the location providing terminal communicates with the first terminal, the first terminal communicates with the second terminal, and the location providing terminal, the first terminal and the second terminal execute the encryption-based location data described in Embodiment 1 of the present disclosure. Facility site selection method for facility site selection.
