Personal Health Records (PHRs) allow patients to have full control over their health data. However, storage and sharing of PHRs still remains a difficult but necessary task, especially when health data is one of the major targets of cyber attacks worldwide. Searchable Encryption (SE) is a feasible solution for this problem and can be augmented by Blockchain to address some of its issues, such as verifiability. Therefore, SE using blockchain is a promising technologies to tackle the challenge of PHR storage and sharing. In this survey, we have explored the research works that use SE and blockchain technology for the same. The work starts with an introduction of cloud, searchable encryption and blockchain. Subsequently, we present a literature survey of the corresponding technologies. We then describe SE in detail and how it fits with blockchain. This is followed by description of noteworthy existing solutions for secure storage and sharing of PHRs. Even though there have been a number of surveys related to SE, none of them have surveyed the use of blockchain with SE or use of SE and blockchain in PHR sharing. The work concludes with a comparative study of these existing solutions and future scope in this direction.

“…The technique used in [18] has the advantage that there is no need to change the user's key after re-encrypting the data by the cloud server. Guo et al proposed a blockchain-based scheme for user revocation, which the blockchain cannot independently receive the whole key from the data user [28]. Instead, the keys are produced between the blockchain and the data user using a secure key issuance protocol.…”

“…Additionally, the scheme uses a group manager to update the group keys of users who have not been recovered and produces re-encryption keys, as well as the decryption cloud server to plan pre-decryption tasks in the cloud. A major drawback of the schemes [18] and [28] is that they are based on different types of Diffie-Hellman problems which are susceptible to being broken by the Shor's quantum algorithm.…”

Attribute-based encryption is a valuable technique for ensuring data privacy and confidentiality in the realm of cloud computing. Using this cryptographic primitive, the data owner can securely store and share data within the cloud environment. On the other hand, in recent years, extensive advances have been made in quantum processors, which have raised hopes of solving certain mathematical problems includes factoring integers and computing discrete logarithms of large numbers. The advent of quantum computers has posed a significant security threat to existing cryptographic protocols. The existing post-quantum attributebased encryption schemes have not satisfied the essential features such as verifiability, user privacy and user revocability, simultaneously. In this paper, we present the first secure, practical and post-quantum attributebased encryption scheme based on rank metric codes. Our scheme enjoys all mentioned features due to utilization of low rank parity check codes. The proposed scheme provides security against chosen plaintext attacks in the standard model, as well as resistance against reaction attacks as a kind of chosen ciphertext attacks. Moreover, at the 256-bit security level, the key size is about 16.5 KB, with an execution time of around 31.2 ms on a desktop. Our implementation results confirm that the proposed scheme is more efficient than the existing post-quantum and classical schemes.INDEX TERMS Attribute based encryption, completeness of the search results, rank metric codes, user privacy, user revocation.

The utilization of cloud storage is increasingly prevalent as the field of cloud computing continues to expand. Several cloud data auditing schemes have been proposed within the academic community to guarantee the availability and integrity of cloud data. Nevertheless, several schemes rely on public key infrastructure and identity-based encryption, introducing intricate challenges associated with certificate management and key escrow. Consequently, we present a certificateless encryption-based blockchain-assisted public cloud data integrity auditing scheme for data integrity. Furthermore, our proposed scheme incorporates blockchain technology to oversee the activities of semi-trusted third-party auditors and resolve the concerns mentioned above. To enhance the efficiency of dynamic data updating and ensure data privacy security, we introduce a new data structure that combines a novel counting bloom filter and a Multi-Merkel hash tree approach. The assumption of the discrete logarithm issue determines the system's security. In contrast, the security model of the scheme is comprehensively delineated. In the part dedicated to performance analysis, we assess the scheme's functionality and computational cost within the framework of existing literature. The experimental results provide proof of the scheme's comprehensive functionality and effectiveness.
