Title
(EN) Method, terminal and system for transmitting key
(ZH) 一种传递密钥的方法、终端及系统
Abstract
(EN) The present invention discloses a method, a terminal, and a system for transmitting a key, and the method comprises the steps of inputting a transmission key of a first key to be transmitted to a POSterminal; inputting the first key to be transmitted to the POS terminal at a key transmission end; and encrypting the first key through the POS terminal by using the transmission key to obtain a keyfile; delivering the key file to the key transmitting end by the POS terminal and delivering the key file to the key receiving end by the key transmission end. The inputting can be done without a personne, therefore the cost of person traveling is reduced, and leakage in the paper delivery mode is avoided. In this way, low-cost key delivery while guaranteeing the security of he transmitted key isrealized.
(ZH) 本发明公开一种传递密钥的方法、终端及系统,将待传递的第一密钥的传送密钥输入一POS终端,密钥发送端将待传递的第一密钥注入所述POS终端,通过所述POS终端采用所述传送密钥对所述第一密钥进行加密,得到密钥文件,所述POS端将所述密钥文件发送给密钥发送端,再由密钥发送端将所述密钥文件发送给密钥接收端,借助POS终端实现密钥的传递,不需要人员出差实现注入,减少人员出差的成本,也不需要担心纸质传递方式的泄密问题,在保证传递的密钥安全可靠的前提下实现低成本的密钥传递。
