“…Multi-User Searchable Encryption (MUSE) Multi-User Searchable Encryption (MUSE) technique was focused in some recent work [8], [9], [10], [11], [14], while to reach the objective these all adopted single key integrated with access control. In [7], [14], multi-user searchable encryption system are constructed to achieve coarse-grained access control by using broadcast encryption and documents were shared by sending searchable encryption key to all users who can access it.…”

Attribute Based Encryption (ABE) is applied in [8], [9], [10], [11], [12], [13] to achieve searching keyword using fine-grained access control. However now in multi-user searchable encryption, control over which document can be accessed by which user is the main problem.…”

Abstract:As cloud computing becomes popular, more and more sensitive information are being centralized into the cloud nowadays. For the protection of data privacy, sensitive data usually have to be encrypted before outsourcing, which makes effective data utilization a very challenging task because all the data which we outsource are in encrypted format. In this paper, we have discussed a few approaches for sharing data on cloud with minimal usage of key. We also discuss few data searching technique over encrypted data. While enjoying the advantage and convenience of cloud storage for data sharing, users are becoming more worried about careless leak of data in the cloud. To address this problem we studied various leakage models.

“…In this notion [2][3][4] [7], an attribute structure is embedded into each user's private key, a signer is capable of creating a signature using the private key he owns, while a verifier can verify the signature using system parameters. Existing literatures have tackled certain issues in ABS such as user traceability [12] [17], user flexible revocation [5] [12], signature with multi-authorities, etc. At the meantime, ABS is widely implemented for providing data authentication [6] in mobile networks.…”

Abstract. Attribute based signature (ABS) is a significant cryptographic notion providing secure authentication during data sharing. A signer can sign a message using the private keys he processes. However, user's private key exposure may happen from time to time and this will bring potential threat to the whole system. Thus, key evolving mechanism should be introduced into ABS schemes. Besides, the efficiency of existing ABS schemes can be further improved since the process of signing and verification require massive bilinear pairings, which occupies costly computing resources on mobile terminal devices. To better tackle the above problems and provides a more secure data authentication method in mobile communication systems, in this paper, we firstly propose a key insulated attribute based signature scheme without pairings (KI-ABS-WP). Then we give the formalized definition as well as the concreted constructions of our scheme. In our KI-ABS-WP, uses needn't run any bilinear pairings, thus the total computation cost has been reduced to a large extent. If key exposure occurs, key insulation mechanism guarantees system's both backward and forward security. Finally, by performance analysis, our KI-ABS-WP is shown to be suitable for data authentication in wireless communications.

“…Similar to the technique in [2], the PHR users in the sharing system in [5] are divided into multiple security domains, which greatly reduces the complexity of key management for PHR owners and PHR users. To guarantee patient privacy, multi-authority ABE [6] are exploited in [5,13]. Lu et al [7] proposed a secure and privacy-preserving opportunistic computing framework for mobile healthcare emergency.…”

Aquesta és una còpia de la versió author's final draft d'un article publicat a la revista Journal of supercomputing. Abstract As an emerging patient-centric model of health information exchange, personal health record (PHR) is often outsourced to be stored at a third party. The value of PHR data is its long-term cumulative record relevant with personal health which can be significant in the future when faced with disease occurrences. As a promising public key primitive, attribute-based encryption (ABE) has been used to design PHR sharing systems. However, the existing solutions fail to achieve several important security objectives, that is, no need for a single authority to issue private keys to all PHR users, user access privacy protection, and user accountability. In this paper, we propose
