Abstract
At present, the protection of data privacy has become one of the research hotspots. However, the classic data privacy protection scheme is based on the classic cryptosystem. The classical cryptosystem is based on the computational complexity of mathematical intractable problems. With the improvement of computer computing power, the security of the classical cryptosystem is seriously threatened. Based on the physical properties of quantum mechanics, using quantum key distribution and quantum teleportation technology, a quantum protection scheme for private data based on trusted center is designed. In theory, this scheme has the unconditional security of quantum cryptography and is independent of the computing power of the attacker.
