Abstract
As the number of sensor network application scenarios continues to grow, the
security problems inherent in this approach have become obstacles that hinder its wide
application. However, it has attracted increasing attention from industry and academia.
The blockchain is based on a distributed network and has the characteristics of nontampering and traceability of block data. It is thus naturally able to solve the security
problems of the sensor networks. Accordingly, this paper first analyzes the security risks
associated with data storage in the sensor networks, then proposes using blockchain
technology to ensure that data storage in the sensor networks is secure. In the traditional
blockchain, the data layer uses a Merkle hash tree to store data; however, the Merkle hash
tree cannot provide non-member proof, which makes it unable to resist the attacks of
malicious nodes in networks. To solve this problem, this paper utilizes a cryptographic
accumulator rather than a Merkle hash tree to provide both member proof and nonmember proof. Moreover, the number of elements in the existing accumulator is limited
and unable to meet the blockchain’s expansion requirements. This paper therefore
proposes a new type of unbounded accumulator and provides its definition and security
model. Finally, this paper constructs an unbounded accumulator scheme using bilinear
pairs and analyzes its performance.
