Lately, China Telecom released the industry’s first quantum secure communication product-‘Quantum Secret Talk’.
This product was created by China Telecom Quantum Technology Co., Ltd., a company controlled by China Telecom.
It has been successfully tested for commercial use in Anhui. Recruit ‘Quantum Secret Dialogue’ friendly experience customers in Anhui Province.
What exactly is “quantum secret talk”?
‘Quantum secret call’ is a security service that uses quantum information technology to protect calls.
As the first domestic mobile communication product that closely integrates 5G and quantum information technology, it directly serves the public, the party, government and military, and enterprises and institutions.
The main feature of ‘quantum secret talk’ is to make full use of quantum random numbers and quantum key distribution mechanisms to generate authentication keys and conversation keys.
The keys are truly random. Every time the user initiates a “quantum secret call”, the call will randomly extract a quantum key in the chip to establish a connection with the background and verify identity information.
After the authentication is passed, a new key is generated in real-time as the session key for authentication. The key is separated from the session key and discarded after use.
In this way, end-to-end encryption from the calling party’s mobile phone to the called party’s mobile phone can be realized.
Even if the voice information of the call is obtained by others, the real content cannot be obtained, and the security is high.
What is the difference between quantum keys and ordinary keys?
The characteristic of quantum keys lies in their randomness. The key generation is based on physical mechanisms rather than mathematical algorithms.
The keys are not reused, and there is no fear of monitoring and deciphering, ensuring ‘one industry, one secret’.
‘Quantum Secret Talk’ has high-level security and is currently applicable to various Android models, combined with the one-click loss report service provided by the telecom backend.
When the mobile phone is lost, the key can be canceled remotely to prevent the key information from being stolen.
Is the quantum secure call service complicated?
If users need to apply for Quantum Secure Call products, they can bring their ID card to the local business office, replace the customized Quantum Secure Call SIM card.
Download the Tianyi Quantum Secure Call APP, only change the card without changing the number, and do not need to change the phone. During each call, users can freely choose between normal calls or quantum secure calls.
What market prospects will the quantum secure call business have?
In the short term, the user groups of quantum secure communication products are mainly users pursuing absolute security such as government affairs, military, finance, large and medium enterprises, etc.
As people’s awareness of personal privacy and information security protection improves, the public market will also usher in broad future Development needs.
At the China Telecom 2020 Tianyi Smart Ecological Expo held in Guangzhou, China Telecom officially released the ‘Quantum Shield Operation’, clarifying that it will provide 10 million+ mobile terminal users with quantum secure call services in the next five years.
