According to the announcement, China Telecom's 'Tianyi No.1 2022' is equipped with a quantum encryption module and a dedicated SIM card, and can encrypt and decrypt voice calls using quantum key distribution . And that.
Quantum key distribution is a method of sending the encryption key of communication by photons in the state of quantum superposition in which quanta exist in multiple states. If the encryption key is intercepted or tampered with by someone, the state of quantum superposition will collapse and it will be immediately discovered that the information has been stolen, so communication that is virtually impossible to hack is possible. It has been.
Zhang Rutong of QuantumCTek, a startup that developed 'Tianyi No.1 2022' in partnership with China Telecom, said, 'When a user initiates a quantum secure call, a private key for verification is randomly generated. Once that verification is complete, the quantum network will generate new real-time keys to encrypt the voice data. These keys are randomly generated, difficult to decrypt, and immediately destroyed after a call. ' Did. In addition, this function can be used only when both during a call use a phone using quantum technology.
'Tianyi No.1 2022' comes in three colors: black, gray and white. The screen size is 6.5 inch FHD, the refresh rate is 90Hz, and the battery is 5000mAh. The chip is a 6nm 5G SoC Tanggula T770 chip made by Ziguang Zhanrui (UNISOC) with a 5G modem, and is equipped with a 48-megapixel main camera, a 120-degree ultra-wide-angle lens, and a lens for portrait photography.
