Embedding of national cryptographic algorithm in Hyperledger Fabric by Qi CAO, Shuhua RUAN, Xingshu CHEN, Xiao LAN, Hongxia ZHANG, Hongjian JIN

“…Hyperledger Fabric is an extensible alliance blockchain platform and provides support for enterprise-level commercial blockchain projects.The cryptographic algorithm is the core technologies of the platform, ensuring the security and non-tampering of the data on the chain.But the original Fabric platform lacks the national cryptographic algorithm support.The embedding and support of the national cryptographic algorithm of the Fabric platform was designed and implemented.Firstly, the interaction logic of between components and the invocation scenario of each type of cryptographic algorithm in the Fabric platform were analyzed, an idea of embedding national cryptographic algorithm support for the platform was proposed.Secondly, the modules and interfaces for SM2, SM3 and SM4 were added to BCCSP of the Fabric platform based on the open source code of national cryptographic algorithm implementation.Thirdly, the interface of cryptographic algorithm invoked by the upper layer of each component is associated to the interface of corresponding national cryptographic algorithms, which realized the invocation support of national cryptographic algorithm for the upper layer applications.Finally, the correctness and effectiveness of the embedded national cryptographic algorithm were verified by creating a fabric-gm test instance.And compared with the performances of the test instance built by the mirror of the native Fabric platform.The experimental results show that the embedded national cryptographic algorithm interfaces are corrected and the generated national cryptographic certificates are effective.Moreover, compared with the native Fabric platform, the network start up time increases by about 3%.In the millisecond unit, the transaction time cost increases by about one time, the dynamic certificate generation time increases by about 9%, and all the performance are within the acceptable range.…”

State-of-the-art survey of smart contract verification based on formal methods by Wenbo ZHANG, Simin CHEN, Lifei WEI, Wei SONG, Dongmei HUANG

“…Smart contract represents an essential application scenario of blockchain technology.Smart contract technology improves programmability and scalability of blockchain, and has broad development prospects.However, a series of security incidents caused a great number of economic losses and weakened users’ confidence in the Ethereum platform.The security of smart contract has become a critical problem that restricts the further development of smart contract.Defects in smart contract code may cause serious consequences and cannot be modified once deployed, it is especially important to verify the correctness of smart contract in advance.In recent years, researchers have obtained many achievements in verification of smart contract, but there is a lack of systematic summary of these research results.Therefore, some basic principles of Ethereum were introduced, including the transaction, gas mechanism, storage and programming language.Eight common types of vulnerabilities in smart contract were summarized and their causes were explained.Some real security events were reviewed and some examples of vulnerability codes were presented.Then, the research work on automatic verification of smart contract based on symbolic execution, model checking and theorem proving was classified and summarized.Three open-source automated tools were selected, including Mythril, Slither and Oyente.And experiments were implemented to evaluate and compare the three tools from the aspects of efficiency, accuracy and the types of vulnerability can be detected.Furthermore, related review articles were surveyed, and the advantages of this paper compared with these works were summarized.The critical problems in the vulnerability detection technology of smart contract were also summarized and the direction of future research was proposed at last.…”
