Abstract_FL The application of wireless sensor networks in the medical field brings great convenience to doctors and patients.The authenticity and integrity of medical data becomes a major problem in the medical industry due to the destruction of patient privacy information during the transmission process.To solve this problem,a certificateless aggregate signature scheme is proposed to protect patient privacy information.However,most schemes cannot resist fully chosen-key attacks and face the key exposure problem.Therefore,this paper proposes a certificateless parallel key-isolated aggregate signa-ture scheme that can resist fully chosen-key attacks.The scheme is based on blockchain technology for data sharing and identity tracking,uses the real-time nature of edge computing to deal with high delay problems in wireless sensor networks,and uses parallel key isolation methods to solve the problem of key exposure.Under the elliptic curve discrete logarithm problem,the scheme is proved to be unforgeable under the random oracle model,and the hash-based strong collision-resistant proofs that the scheme can resist fully chosen-key attacks.Efficiency analysis using MIRACL library shows that this scheme is more efficient than other related schemes in each stage,and has lower communication overhead.
