| 1. | The four secure key management mechanisms , including kp ( protect key ) , kd & ke ( decrypt & encrypt key ) , kw ( working key ) and km ( message key ) , which can protect the key " end - to - end " and ensure the key only use once
采用了保护密钥尤尸、双钥密钥(犬d进犬e ) 、工作密钥kw和消息密钥尤材等四级密钥管理体制。该体制可以保证密钥的端端性和一次一密性。 |
