Session key Online phase: Session key establishment

During the initialization of a sensor network, each node must discover all of the half-key spaces shared with its neighboring nodes within its wireless communi cation range. The discovery of shared half-key spaces may be accomplished by the broadcasting of key-space identifiers among nodes. If the number of half-key spaces shared between two neighboring nodes is more than a user-defined
threshold q, then we say that these two nodes could establish a communication link; otherwise, there is no communication link between these two nodes. The rationale behind this setting is to avoid potential attacks, due to an insufficient number of session key candidates.
