Data Requester plays an important role in many wireless data provider network applications for efficient data collection, localized data provider reprogramming (5), and for distinguishing compromised data providers. However, for pair wise key production in data provider networks that make use of the existing key pre- distribution schemes and authentication between data requesters and data providers, the task of data requesters for data collection enhance a new security challenge :huge number of keys are determined by the attacker easily by capturing the few amount of nodes in the basic key pre-distribution schemes and hence, can obtain control of the network by producing a replicated data requester preloaded with some compromised keys. This article describes a three-tier general framework or structure that allows the use of any pair wise key pre-distribution scheme as its basic component. The new framework requires two separate key pools, one for the data requester to access the network, and one for pair wise key establishment between the data providers. To reduce the damages caused by data provider replication attacks, we have strengthened the authentication mechanism in the proposed framework. Through detailed analysis, we show that our security structure has a higher network security to a replication of data requester attack as compared to the polynomial pool-based scheme.
