In In-networking storage Wireless Sensor Networks, sensed data are stored locally for a long term and retrieved on-demand instead of real-time. To maximize data survival, the sensed data are normally distributively stored at multiple nearby nodes. It arises a problem that how to check and grantee data integrity of distributed data storage in the context of resource constraints. In this paper, a technique called Two Granularity Linear Code (TGLC) that consists of Intra-codes and Inter-codes is presented. An efficient and lightweight data integrity check scheme based on TGLC is proposed. Data integrity can be checked by any one who holds short Inter-codes, and the checking credentials is short Intra-codes that is dynamically generated. The proposed scheme is efficient and lightweight with respect to low storage and communication overhead, and yet checking validity is maintained. Our conclusion is justified by extensive analysis.
