Survey on blockchain privacy protection techniques in cryptography by Feng LIU, Jie YANG, Jiayin QI

“…In recent years, the issue of data privacy has attracted increased attention, and how to achieve effective privacy protection in blockchain is a new research hotspot.In view of the current research status and development trend of blockchain in privacy protection, the privacy protection methods of blockchain in transaction address,prophecy machine and smart contract were explained, and the privacy strategies of blockchain in the protection of basic elements were summarized.Based on high-level literature at home and abroad, two types of blockchain cryptographic protection methods and usage scenarios were analyzed, including special cryptographic primitives and post-quantum cryptography.The advantages and disadvantages of seven cryptographic techniques applicable to current blockchain privacy protection were also reviewed, including attribute-based encryption, special data signature, homomorphic encryption, secure multi-party computation, zero-knowledge proofs, and lattice ciphers.It was concluded that the privacy protection of blockchain applications cannot be achieved without cryptographic technology.Meanwhile, the blockchain privacy protection technologies were analyzed in terms of both basic element protection and cryptographic protection.It was concluded that it was difficult to effectively solve the privacy problem only from the application and contract layers of the blockchain, and various cryptographic technologies should be used to complement each other according to different needs and application scenarios.In addition, according to the current development status of blockchain privacy cryptography, the narrative was developed from blockchain basic element protection and cryptography-based protection.From the perspectives of both endogenous basic element security and exogenous cryptographic privacy security, basic element privacy protection should be studied first, followed by an in-depth analysis of cryptographic protection techniques for blockchain privacy.The strengths and weaknesses and the potential value of the privacy handling aspects of the corresponding safeguards should be measured in terms of the development of technology in conjunction with practical applications, while considering the timeliness of the technology.Finally, an outlook on the future direction of blockchain privacy protection technologies was provided, indicating the issues that need to be addressed in focus.…”

Anti malicious KGC certificateless signature scheme based on blockchain and domestic cryptographic SM9 by Fei TANG, Ning GAN, Xianggui YANG, Jinyang WANG

“…The certificateless cryptosystem can solve the problems of certificate management and key escrow at the same time, but its security model always assumes that Type II adversary (named malicious KGC) will not launch public key replacement attacks.This security assumption has certain limitations in real-world applications.As an efficient identity-based cryptographic scheme, SM9 signature scheme adopts R-ate bilinear pairing which has good security and high computational efficiency.However, it requires KGC to generate and manage keys for users, so it has the problem of key escrow.In view of the above problems, a certificateless signature scheme against malicious KGC was constructed based on blockchain and SM9 signature algorithm.Based on the properties of decentralization and tamper-proof of blockchain, the proposed scheme used the smart contract to record part of the public key corresponding to the user’s secret value on the blockchain.Then, the verifier can revoke the smart contract to query the user’s public key during the signature verification stage.Therefore, the proposed scheme ensured the authenticity of the user’s public key.The user’s private key consisted of the partial private key generated by KGC and a secret randomly chosen by the user.The user required the partial private key generated by KGC to endorse his identity identifier when the user generates the private key for the first time.Subsequently, the private key can be independently updated by changing the secret and the corresponding partial public key.During this process, the identity remains unchanged, which provided a viable solution for key management in decentralized application scenarios.The blockchain relied on the consensus mechanism to ensure the consistency of the distributed data.Based on the traceability of the blockchain, the change log of user’s partial public key was stored in the blockchain, which can trace the source of malicious public key replacement attacks and thereby prevent malicious KGC from launching public key replacement attacks.According to the experimental simulation and security proof results, the total overhead of signature and verification of the proposed scheme is only 7.4ms.Compared with similar certificateless signature schemes, the proposed scheme can effectively resist public key replacement attacks and has higher computational efficiency.…”
