Blockchain-based distributed EHR fine-grained traceability scheme by Zuobin YING, Yuanping SI, Jianfeng MA, Ximeng LIU

“…Aiming at the key management of electronic health records (EHR) in a distributed system and user identity tracing issues, a distributed EHR fine-grained traceability scheme based on blockchain was proposed.Combining chameleon hash and zero-knowledge proof technology, the registration of nodes on the blockchain and the generation of identity certificates were realized, and the traceability of malicious users on the blockchain was realized.Besides, given the single point of failure problem of key management, the attribute-based encryption scheme of distributed ciphertext strategy was designed to achieve secure and fine-grained data access control, and multiple decryption agency blockchain nodes were set up to jointly distribute the attribute private keys of user nodes.The security analysis shows that the traceable distributed key generation attribute-based encryption algorithm based on the blockchain is adaptively secure under the random oracle model, and through experiments, the feasibility and practicability of the proposed scheme are shown.…”

Efficient anonymous password-based authenticated key exchange scheme by TAN Shi-chong, PANG Liao-jun, SU Wan-li, WANG Yu-min

“…,the key was used for data confidentiality and/or integrity）.There has been much interest in password-authenticated key exchange protocol which remains secure even when users choose passwords from a small space of possible passwords,such as a dictionary of English words.A password-based authenticated key exchange scheme was proposed.The analysis shows that the scheme is secure against dictionary attack under the computational Diffie-Hellman intractability assumption,and preserves user privacy and achieves unlinkability.Furthermore,since denial-of-service（DoS） attacks have become a common threat,DoS-resistantance is a design consid-eration and the scheme is proved to be secure against denial-of-service attacks.…”
