央视新闻客户端7月9日报道,信息安全是大家关注的焦点,使用量子技术对信息进行加密是目前最有效的办法之一。首个商用量子通信专网——济南党政机关量子通信专网近日完成测试,保密性、安全性、成码率的测试均达到设计目标,整套网络预计今年8月底正式投入使用。
央视记者张伟:这里是济南党政机关量子通信专网的核心机房,专网内的所有通信数据,都是通过这里的专业设备,量子加密后,与周边数百平方公里的,近200个终端进行保密通信。
济南党政机关量子通信专网从5月开始测试以来,完成了50多个项目的测试,所有用户之间的通信实现了每秒产生4000多个密码的绝对保密性。
量子是能量最基本、最小不可分割的单元。未知量子态无法精确克隆,只要有人试图复制,就会产生误码,会被发现。这些特性使得量子态通信在传输过程中有了绝对安全性。济南市党政机关量子通信专网,是继济南量子通信试验网之后,第一个真正商用化的量子通信专网。济南量子通信试验网目前是世界上规模最大、功能最全的量子通信城域网。
济南量子科学研究院院长助理周飞:济南市党政机关量子通信专网8月份建成之后,在国防、金融、电力等等领域作为示范进行推广。它的测试成功也是中国乃至全球量子通信产业一个标志性的成果。
量子通信技术被认为是“保障未来信息社会通信机密性和隐私的关键技术”,目前我国在量子通信的技术研究方面处于世界领先水平。欧洲、美国、日本等发达国家以及众多国际大公司都竞相发展这项技术。
