PROXY ANONYMOUS COMMUNICATION METHOD BASED ON HOMOMORPHIC ENCRYPTION SCHEME
Document Type and Number:
WIPO Patent Application WO/2021/109756
Kind Code:
A1
Abstract:
Disclosed in the present invention is a proxy anonymous communication method based on a homomorphic encryption scheme. Said method comprises: S1, a sending end performing original encryption on target data to obtain ciphertext data c1; S2, the sending end sending the ciphertext c1 to a server; S3, the server performing homomorphic encryption on the ciphertext data c1 to obtain ciphertext data c2; S4, the server sending the ciphertext data c2 to a receiving end; and S5, the receiving end decrypting the ciphertext data c2 to obtain the ciphertext data c1. Said method is mainly used for reliable and complete transmission of privacy data (mainly for position data) of participating vehicles in the Internet of Vehicles, and achieves the safe operation of vehicles in the Internet of Vehicles is achieved by improving the security and confidentiality of the position data of the participating vehicles in the Internet of Vehicles, having certain economic benefits and engineering practicability.
