MAC FRAME PROVISION METHOD AND APPARATUS CAPABLE OF ESTABLISHING SECURITY IN IEEE 802.15.4 NETWORK
摘要：
A medium access control (MAC) frame provision method establishes security in an IEEE 802.15.4 network. A MAC frame is generated, which includes a MAC header, a payload field, and a frame check sequence (FCS) field, the payload field including relevant main data according to a frame type defined in the MAC header. A disguised decoy data sequence number (DSN) is generated and inserted into the MAC header. A real DSN, which is a corresponding transmission sequence number of the MAC frame, is generated and inserted into the payload field. The MAC frame is transmitted, including the encrypted payload field, to a counterpart node. A MAC ACK frame acknowledges reception of the transmitted MAC frame; and a DSN is compared in the received MAC ACK frame with the real DSN. An authentication of the counterpart node is performed when the received MAC ACK frame is equal to the real DSN.
摘要（中）：

介质访问控制（MAC）帧提供方法在IEEE 802.15.4网络中建立安全性。 生成MAC帧，其包括MAC头，有效载荷字段和帧校验序列（FCS）字段，所述有效负载字段根据在MAC报头中定义的帧类型包括相关主数据。 生成伪装的诱饵数据序列号（DSN）并将其插入到MAC头中。 产生作为MAC帧的相应传输序列号的真实DSN并将其插入到有效载荷字段中。 将MAC帧发送到对方节点，包括加密的有效载荷字段。 MAC ACK帧确认所发送的MAC帧的接收; 并且在接收到的MAC ACK帧中与DSN进行比较。 当接收的MAC ACK帧等于实际DSN时，执行对方节点的认证。
