阅读说明：本技术 锚密钥生成方法、设备以及系统 (Anchor key generation method, device and system ) 是由 吴�荣 张博 甘露 于 2018-04-25 设计创作，主要内容包括：本申请实施例提供了一种锚密钥生成方法,设备以及系统。其中,所述方法包括：第一通讯设备接收第二通讯设备发送指示标识,其中,指示标识用于指示终端的接入方式；第一通讯设备向第三通讯设备发送指示标识；第一通讯设备接收第三通讯设备返回的中间密钥,其中,中间密钥是根据指示标识生成的；第一通讯设备根据中间密钥生成锚密钥,其中,锚密钥对应终端的接入方式；第一通讯设备将锚密钥发送给第二通讯设备,以供第二通讯设备根据锚密钥为接入方式推衍下层密钥。上述方法能够为不同的接入方式生成统一的锚密钥,并且实现了将不同接入方式的锚密钥,以及基于锚密钥生成的下层密钥进行隔离。(The embodiment of the application provides an anchor key generation method, equipment and a system. Wherein the method comprises the following steps: the method comprises the steps that first communication equipment receives an indication mark sent by second communication equipment, wherein the indication mark is used for indicating an access mode of a terminal; the first communication equipment sends an indication mark to the third communication equipment; the first communication equipment receives an intermediate key returned by the third communication equipment, wherein the intermediate key is generated according to the indication identifier; the first communication equipment generates an anchor key according to the intermediate key, wherein the anchor key corresponds to the access mode of the terminal; the first communication equipment sends the anchor key to the second communication equipment so that the second communication equipment can derive the lower-layer key according to the anchor key as an access mode. The method can generate uniform anchor keys for different access modes, and realizes the isolation of the anchor keys of different access modes and the lower layer keys generated based on the anchor keys.)
