In the mobile wireless communication network, the network is a dynamic topology. In addition, mobile ad hoc network is a vulnerable network. The message transmitted from source to destination may traverse several intermediate nodes. The sender and receiver need set up a routing path from source to destination. It is a hard problem to build a secure routing path from source to destination because an attacker, malicious node or eavesdropper, may attack any part of a routing path from source to destination. Therefore, to prevent or to detect the randomized attacks from an attacker becomes the difficult problem. In order to deal with randomized attacks in the routing path, this paper designs a secure quantum mechanism which can provide that the transferred quantum packet is secure between the sender and receiver. This mechanism proposes a new concept, a flexible quantum frame which randomly permutes the data qubits and the control qubits. In addition, the proposed mechanism supports a special relation between the data qubits and the control qubits. The sender and receiver have the agreement to know this special relation. Based on this special relation, the data security of transferred quantum packet can be achieved.
