摘要：
A mutual authentication method in a Downloadable Conditional Access System (DCAS) is provided. The mutual authentication method may receive authentication-related information about authentication between an authentication unit and a security module (SM) from a Trusted Authority (TA), generate an authentication session key using the authentication-related information, transmit the authentication session key by the authentication unit to the SM through a Cable Modem Termination System (CMTS), and control a Conditional Access System (CAS) software to be downloaded to the SM from the authentication unit, when the authentication is completed by the authentication session key.
摘要（中）：
提供了可下载条件访问系统（DCAS）中的相互认证方法。 相互认证方法可以从可信授权（TA）接收认证单元和安全模块（SM）之间的认证的认证相关信息，使用认证相关信息生成认证会话密钥，通过认证相关信息发送认证会话密钥 通过有线调制解调器终端系统（CMTS）向SM发送认证单元，并且当通过认证会话密钥完成认证时，控制从认证单元下载到SM的条件访问系统（CAS）软件。
