中国电信首发“量子高清密话”：采用国产芯片的量子SIM卡

在5月17日世界电信和信息社会日到来之际，中国电信发布业内首款基于量子信息技术的VoLTE加密通话产品——天翼量子高清密话。该产品采用国产定制手机、量子安全SIM卡和国密算法“三重保护”，在保障终端原生支持、VoLTE高清通话基础上，为用户提供“管-端-芯”一体化安全防护。

据介绍，天翼量子高清密话搭载中国电信定制终端，采用国产芯片的量子安全SIM卡，自主研发量子安全中间件，在手机侧完成对VoLTE话音数据的加解密，有效防止通话在网络传输中被监听。

用户每次发起“量子密话”都会随机抽取卡内密钥校验用户身份，认证通过后再由量子网络实时生成一个新密钥加密会话数据。密钥真随机、难破译，会话结束后密钥立刻被废弃。

天翼量子高清密话不降低原有电信VoLTE业务的话音清晰度，用户通过拨号盘即可直接拨打加密通话，当任一方不支持此项业务时，通话自动回落到原有VoLTE通话，操作便捷，接通快，无丝毫顿挫感，在保障通话高清品质的同时，极大增强通话的安全保密性。

中国电信一直以来积极推动量子科技社会化应用，早在2021年1月1日，就正式推出首个运营商级的量子安全产品——天翼量子密话，实现VoIP量子加密通话。

用户开通此项业务，更换量子安全SIM卡，即可通过手机端下载安装天翼量子APP享受加密通话、加密短信服务，目前该项服务终端用户规模近30万。

此次全新发布的天翼量子高清密话，则是中国电信“量子+加密通话”产品族中的新成员，已在北京、安徽、广东等地区开展试商用，用户可以致电10000号客服进行咨询。

According to reports, Tianyi Quantum HD Secret call carries China Telecom customized terminal.Using the quantum security SIM card of domestic chip, the quantum security middleware is developed independently, and the encryption and decryption of VoLTE voice data is completed on the mobile phone side.To effectively prevent calls from being monitored during network transmission

Every time the user initiates “Quantum Secret talk”, the key in the card is randomly selected to verify the user’s identity, and then a new key is generated by the quantum network to encrypt the session data in real time. The key is really random and difficult to decipher, and it is discarded immediately after the end of the session.

Tianyi Quantum HD Cryptography does not reduce the voice clarity of the original telecom VoLTE service. Users can dial encrypted calls directly through the dial.When either party does not support this service, the call automatically falls back to the original VoLTE call, which is easy to operate, connects quickly, without the slightest sense of frustration, which greatly enhances the security and confidentiality of the call while ensuring the HD quality of the call.

China Telecom has been actively promoting the social application of quantum technology. As early as January 1, 2021, China Telecom officially launched the first carrier-level quantum security product, Tianyi Quantum Secret talk, to realize VoIP quantum encrypted calls.

When users activate this service and replace the quantum security SIM card, they can download and install Tianyi quantum APP on their mobile phones to enjoy encrypted calls and encrypted text message services. at present, the number of end users of this service is nearly 300000.

The newly released Tianyi Quantum High definition Secret call is a new member of China Telecom’s “Quantum + encrypted call” product family. It has been tested for commercial use in Beijing, Anhui, Guangdong and other regions. Users can call customer service 10000 for consultation.
