Abstract: A method and a system for distributing a key using an N dimension lattice of a sensor network are provided to reduce overhead for calculating a shared key and a pass key by distributing shared keys corresponding to a position on each axis in a sensor node. A distributing server performs one-to-one correspondence about positions inside an N dimension lattice and all sensor nodes, and performs one-to-one correspondence about positions on each axis of the N dimension lattice and a plurality of shared keys. The distributing server distributes the shared keys corresponding to the positions on each axis of a position inside the lattice of each sensor node(S10). The sensor node finds a shared key having a position on the same axis as the other sensor node, generates a symmetric key by the shared key, and transmits data to the other sensor node(S20). The sensor node transmits a pass key to the other sensor node via a direct middle node having a position on the same axis about the sensor node and the other sensor node(S30). The other sensor node decodes the data encrypted by the pass key and the symmetric key(S50).

Abstract: A clustering routing method for energy and distance of a wireless sensor network and a device thereof are provided to make a size of a cluster small by increasing selection probability of a cluster head according to a distance to a data collecting device, thereby realizing uniform energy consumption of the cluster head. Each sensor node determines whether it is selected as a cluster head by probability having a bigger value as it is farther from a collecting device(S11). A sensor node which is not selected as a cluster head selects one among the selected cluster heads(S12). The sensor node transmits sensing information by the selected cluster head and the cluster head merges the sensing information and transmits it to a data collection device(S13).

Abstract: A dual authentication method in a mobile network is provided to prevent a fail of the authentication in a ping-pong state and perform authentication of a mobile node in AAA(Authentication, Authorization, and Accounting) environment by preventing performing dual authentication when the mobile node reaches the ping-pong state. A dual authentication method in a mobile network includes the steps of: performing authentication for a mobile node by re-using authentication information used in a previous access router without requesting necessary information for the authentication to an AAA server. The dual authentication method is performed by using an IBE(Identifier Based Encryption) scheme. The dual authentication method is performed under mobile IPv6 environment. When the mobile node is under a ping-pong state which the mobile node moves to an overlapped space of a previous access router and a new access router, the mobile node generates a registration message based on a router advertisement message received from new access router.
