    • PROBLEM TO BE SOLVED: To provide a communication device, a SATA communication device, a system, an enhanced port multiplier, and a method capable of minimizing defects of a standardized protocol such as a SATA protocol. SOLUTION: The communication device, the SATA communication device, the system, the enhanced port multiplier, and the method are provided for establishing a covert communication channel in a protocol compliant link. The communication device as one of embodiments includes a link interface and supplemental message interface. The link interface is formed to communicatively combine the communication device so as to access a data stream passing through the link according to the standardized protocol. The supplemental message interface is formed to exchange a supplemental message with the data stream to establish a covert communication channel in the link. The supplemental message supplements the standardized protocol without violating the protocol. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:提供通信设备,SATA通信设备,系统,增强端口倍增器以及能够最小化诸如SATA协议的标准化协议的缺陷的方法。 解决方案:提供通信设备,SATA通信设备,系统,增强端口倍增器和方法,用于在协议兼容链路中建立隐蔽通信信道。 作为实施例之一的通信设备包括链路接口和补充消息接口。 链路接口形成为通信地组合通信设备,以便根据标准化协议访问通过链路的数据流。 补充消息接口形成为与数据流交换补充消息以在链路中建立隐蔽通信信道。 补充消息补充了标准化协议,而不违反协议。 版权所有(C)2007,JPO&INPIT
