Problems solved by technology
[0006] The second is that most of its security mechanisms are based on the computational complexity assumptions of difficult problems such as factorization of large numbers and discrete logarithms, and there are unavoidable security threats
Quantum computing can break these difficult problems in an effective time, making electronic network lottery based on computational complexity assumptions no longer safe in the face of attacks with quantum computing capabilities

The invention relates to a quantum network lottery method based on multi-particle entanglement, and the method comprises the steps that S1, a user participating in lottery sends identity information to a lottery management mechanism to complete the registration, and the lottery management mechanism shares an identity key with the user through a QKD transceiver; and S2, the lottery management mechanism prepares a lottery quantum state for a lottery user, and regroups all particles to facilitate subsequent quantum distribution; S3, the lottery management mechanism generates a random secret codeand stores the random secret code in a memory, and test particles are prepared for each lottery user by using the identity key and the secret code; S4, the test particles are randomly inserted into the regrouped lottery quantum states by the lottery management mechanism, and quantum information is transmitted through a classical quantum fusion channel; S5-S6, the lottery user and the lottery management mechanism verify identity information of the two parties by using the test particles; S7, quantum state safety detection; S8, the lottery user discards the particles used in the quantum state security test, and measures the remaining particles to obtain lottery information.
Description
technical field [0001] The invention belongs to the technical field of quantum communication and information security, and specifically relates to a lottery method that can realize absolute fairness and notarization based on multi-particle entanglement in a quantum network. Background technique [0002] Drawing lots is a common activity in daily life and is often used to make a certain decision fairly. The traditional lottery methods mainly include paper lottery, long and short stick lottery, etc., which require the user to draw on the spot in actual operation. This way of lottery not only leads to poor enforceability, but also makes it difficult to ensure fairness and notarization. With the rapid development of computer networks and information technology, electronic network lottery came into being, which enables users anywhere in the world to establish contact within a very short period of time, and can quickly complete the lottery regardless of geographical and time issue...
