摘要： Provided is a digital cable system and method for protecting a secure micro (SM) client, and more particularly, a digital cable system and method for protecting an SM program that can improve the security of an SM program through authentication of a host and integrity verification of the SM program. A method of protecting an SM program includes: receiving host authentication information associated with a host from a trusted authority; verifying validity of the secure micro program based on the host authentication information; and sending, to an authentication proxy, a HostStateInformation message that includes host state information associated with validity verification information of the SM program.
摘要翻译：提供了一种用于保护安全微服务（SM）客户端的数字电缆系统和方法，更具体地说，一种用于保护SM程序的数字有线系统和方法，该SM程序可以通过对主机的认证和完整性验证来提高SM程序的安全性的SM程序。一种保护SM程序的方法包括：从可信管理机构接收与主机相关的主机认证信息; 基于主机认证信息验证安全微程序的有效性; 以及向认证代理发送包括与SM程序的有效性验证信息相关联的主机状态信息的HostStateInformation消息。
