“…They proposed a certificate less Proxy Re‐Encryption (PRE) scheme that realizes secure mobile data sharing and prevents data leakage from cloud proxy server. In a similar work, Li et al 6 suggested a scheme called PRE with equality test for efficient sharing of the searched healthcare data without revealing secret key and plain text. Conventional methods of storing data suffer from data security issues such as leakage, unauthorized access, and centralized storage in spite of the advantages of cloud‐based storage.…”

Healthcare Records are becoming more valuable than ever due to the emergence of various new diseases and the current pandemic. These records are scattered throughout multiple healthcare providers in several places. Keeping them in physical form is time-consuming; thus, they need to be kept in electronic form. Electronic Healthcare Records (EHRs) are mostly managed at the individual company level, creating a single point of failure and exposing users to various security risks, including amateur-level attacks and data breaches by hackers. This article proposes a permissioned blockchain-based framework to overcome the above issues for secured storage and sharing of EHRs over the network. For the overall implementation of the framework Hyperledger Fabric (HLF), InterPlanetary Distributed File System (IPFS), and Identity Based Proxy Re-Encryption (IB-PRE) algorithm are used. To create proposed blockchain network, HLF is used. To manage EHRs on the blockchain, IPFS is used where the actual encrypted massive data is stored off-chain, and their corresponding hash values are stored on the blockchain. Further, IB-PRE algorithm is used to share EHRs in a safe manner, where a proxy node retrieves requested data from IPFS, performs re-encryption, and returns the re-encrypted data to the requester thus, ensures user privacy and data integrity. Finally, the Hyperledger Caliper tool is used to run a performance test to check the system efficiency in terms of throughput and latency. Features and performance-based comparisons of the proposed and existing related work are made to demonstrate the effectiveness.

HSC-MET: Heterogeneous signcryption scheme supporting multi-ciphertext equality test for Internet of Drones

et al. 2022

Internet of Drones (IoD) is considered as a network and management architecture, which can enable unmanned aerial vehicles (UAVs) to collect data in controlled areas and conduct access control for UAVs. However, the current cloud-assisted IoD scheme cannot efficiently achieve secure communication between heterogeneous cryptosystems, and does not support multi-ciphertext equality tests. To improve the security and performance of traditional schemes, we propose a heterogeneous signcryption scheme (HSC-MET) that supports multi-ciphertext equality test. In this paper, we use a multi-ciphertext equality test technique to achieve multi-user simultaneous retrieval of multiple ciphertexts safely and efficiently. In addition, we adopt heterogeneous signcryption technology to realize secure data communication from public key infrastructure (PKI) to certificateless cryptography (CLC). At the same time, the proposed scheme based on the computation without bilinear pairing, which greatly reduces the computational cost. According to the security and performance analysis, under the random oracle model (ROM), the confidentiality, unforgeability and number security of HSC-MET are proved based on the computational Diffie-Hellman (CDH) problem.

“…Bhatia et al 6 proposed a lightweight EHR sharing scheme in cloud, which realizes secure data sharing, and cannot leak original EHR to the cloud proxy server. Li et al 7 put forwards a secure data sharing scheme for healthcare systems, which realizes efficiently data search and flexibly data sharing without disclosing the plaintext and the secret key. Although the cloud computing technology realizes the safe storage of EHR, yet the traditional method of cloud storage still brings some problems of data security, such as centralized storage, data availability, privacy leakage, and high computational overhead.…”

The sharing of electronic health records (EHR) helps the patients increase the accuracy of treatment, while promoting the development of the hospital and the research of medical field compared to traditional paper-based medical records.However, due to the sensitivity of medical data and the difference of the standard about EHR, it is likely to lead to some security problems such as the leakage of patient's privacy and the difficulty of data sharing. To accomplish the secure storage and effective sharing of EHR, we propose an efficient and anonymous multi-message and multi-receiver EHR sharing scheme without secure channel based on blockchain (BEAMMRS). We use blockchain technology and cloud server to store EHR together, which ensures the security and immutability.Moreover, we combine certificateless public key cryptography and elliptic curve cryptography (ECC) to solve the certificate management burden and key escrow problems. Our scheme utilizes multi-message and multi-receiver signcryption algorithm to enable medical data providers to send different messages to multiple data requesters by executing one signcryption operation, which satisfies the multi-message sending requirements of the data providers in the communication environment. Meanwhile, the key generation center (KGC) sends the pseudo partial private key to the data user through the public channel. Only the authorized data user can successfully find out the real partial private key, which avoids the key leakage and economic cost caused by the secure channel. Security analysis and performance evaluation demonstrate that the proposed BEAMMRS scheme meets stronger security and higher computational efficiency than other similar schemes.
