METHOD AND SYSTEM FOR DISTRIBUTING SECERET KEY IN MICRO LOW POWER SENSOR NODES

摘要

A method and a system for distributing a secret key are provided to obtain a defensive ability about a security attack by storing a secret key within an application program. A transmitting part(410) transmits a symmetric secret key to a plurality of sensor nodes. A secret part(420) controls each sensor node, and encodes the transmitted symmetric secret key into a predetermined first secret key. A storage control part(430) stores the encoded symmetric secret key to a storage space. The storage control part stores the first secret key to an application program related to a data communication between the sensor nodes.
