冯传岗一、密钥类型现代数字CAS(Conditional Access System:条件接收系统)普遍采用对称加密算法和公开密钥加密算法(即:非对称加密算法)相结合CA(Conditional Access:条件接收)方式,保证对海量数据流的快速加密,以及在不安全信道上传递加密密钥的安全性。现代数字CAS的密钥类
Feng Chuan-gang First, the key type Modern digital CAS (Conditional Access System: Conditional Access System) commonly used symmetric encryption algorithm and public key encryption algorithm (ie: asymmetric encryption algorithm) combined CA (Conditional Access: conditional access) Fast encryption of massive data streams and the security of passing encryption keys over insecure channels. The key class for modern digital CAS
