Big data in military equipment is the foundation of realizing military modernization and intelligentialize. Equipment data sharing plays a vital role in realizing equipment visual management, integrating equipment supply chain and optimizing command control system. Recently, each military department mainly adopts centralized architecture to build equipment system independently, and stores and maintains its own equipment data. When confidential data is shared across organizations and departments, its security problem is one of the main challenges. Blockchain is a distributed chain ledger technology with the characteristics of decentralization, non-tampering, traceability, stability and reliability, which has a broad development prospect in the military field. Blockchain technology and cloud computing can solve the security problem of equipment data storage and the trust problem between different entities. Smart contract and ciphertext policy attribute based encryption provide automatic equipment data sharing to break the "information island" phenomenon in the traditional military equipment systems.
