Recently, the voice of new technology devolvement has gone louder. I am really interested in cyber security, especially attacking password and established safe networking environment which means relative with Quantum Safe Cryptography. You must be curious about what is quantum encryption? For example, if the quantum computing is a classic encryption algorithm to all the spear, the quantum cryptography is a shield against quantum computing attack! By using quantum key generation and transmission, like a never stolen “keys”, not based on mathematical principles, so cannot be calculated because have special encryption channel for transmission, so it can be call the most safe security technology.

In 1989, Bennett and his colleagues, John a. Smolin and in Gilles Brassard decided to explore a ground-breaking experiment. According to the principle of quantum mechanics, they demonstrated a new technology. Since 2003 Switzerland and the United States in New York City’s magical quantum science and technology are published can transmit quantum key commodities, transmission distance of more than 30 cm in the Bennett experiment. And NEC products, it sends over 150 km far away. In 1999, they founded the magical quantum science and technology. If the eavesdropper eve wants to read a string of photons, quantum modality made her unable to use two kinds of filter to detect point to a photon.

The largest benefits of Quantum Cryptography technology is safe and excellent security defence which means there is no way for attacker to finish attack without permit. Once the Quantum Safe Cryptography is conducted, if the hacker stalks the encrypted message, caused to change the pattern of the photon, it will be easier to notice the abnormal by the authorised user to make sure no data leakage.

Quantum Cryptography have absolute security features, not only in the field of information such as national security, financial security has important application value and prospect, and gradually into the People’s Daily life, the earth to promote the development of the national economy. Scientists proves that a quantum computer can theoretically create and implement virtually unforgeable quantum checks, especially argues that with the

development of quantum cryptography, quantum checks is going to be used in our daily life. This is a kind of security than the current digital currency trading system.  And as people gradually into the era of quantum computing, the current digital encryption is regarded as the solid currency, in the future it may encounter some hackers “blow” to dimension reduction.

In the near future, Quantum encryption technology will be close to people’s life and apply in daily life. It can bring the positive influence on the internet, especially to protect our privacy or some government secrets. Otherwise, the hacker can utilize the encrypted message to do the criminal, the consequences would be unimaginable. But fortunately, quantum cryptography can drive people to the safer and more secure generation.
