摘要：To enhance security in distributed networks, such as ad hoc networks, it is important to evaluate the trustworthiness of participating entities since trust is the major driving force for collaboration especially in route formation from source to destination. Wireless broadcast is an effective approach to find route info rmation among number of nodes. To provide secure access to routing table in wireless route formation, symmetric key-based encryption is used to ensure that only nodes who own the valid keys can decrypt the route information. Regarding various broadcasts, an efficient key management to distribute and change keys is in great demand for access control in route establishment. In this paper, we propose an efficient key management scheme (namely SCRFKM to handle key distribution with regarding to complex route formation possibilities and node activities. SCRFKM is designed to have the following advantages. First, it supports all route request activities in MANETs. Second, in SCRFKM, a node only needs to hold one set of keys for all req uested route formation operations, instead of separate sets of keys for each request. Third, SCRFKM identifies the minimum set of keys that must be changed to ensure routing security and minimize the rekey cost. Our simulations show that SCRFKM can save about 25% of communication overhead in the broadcast channel and about 30% of decryption cost for each node, compared with logical key hierarchy based approaches.
