使用这些值创建两个DES加密密钥，并为每一组添加一个奇偶校验位，这样即可创建出64位的密钥。
These values are used to create two DES encryption keys, one from each half with a parity bit added to each to create 64 bit keys.
方案不仅支持系统内人员和设备的密钥管理、身份认证及公钥密码运算，而且还对加密密钥进行管理。
This scheme not only supports secret key management and identity authentication of personnel and equipment, but also constructs secret key management center and manages encrypted key of the system.
因此，如果卫星在量子状态下编写了加密密钥，任何截取行为都会被发现。密钥就会随之发生变化，从而失效。
So, if the satellite were to encode an encryption key in that quantum state, any interception would be obvious. It would also change the key, making it useless.
当算法公开时，在计算上不可能由加密密钥求解解密密钥，因而可以将加密密钥公开，即公开密钥。
When the algorithms open, the decryption key can not be calculated by encryption key so the encryption key could be open, only keep decryption key secret, that is public key.
