Quantum encryption chip is a new kind of security chip based on quantum communication theory.
Here's how it works:
1. Information transfer based on quantum effects such as single photon or photon polarization state.
(2) Any attempt by a third party to monitor or tamper with the transmitted quantum state will cause a failure of the quantum effect and the information will be disrupted.
3. The sender and receiver exchange some detection results through the open channel to know whether there is a third party eavesdropping, and exchange a shared key in the open channel.
4. Use the unconditional security key obtained through quantum effect for subsequent classic encrypted communication.
It has the following advantages over traditional mathematical encryption:
1. Security is hard to crack based on physical effects.
2. Third-party eavesdropping can be directly detected and the fault Tolerant mechanism is adopted.
3. With the development of quantum computers, traditional algorithms may be broken, while quantum encryption remains secure.
So simply put, the quantum encryption chip uses the principle of quantum communication, which can provide more secure communication encryption protection than the traditional algorithm.
