Cloud Computing has attracted interest as an efficient system for storing and access of data. Sharing of personal electronic health record is an arising concept of exchanging health information for research and other purposes. Cconfidentiality except for authorized users, and access auditability are strong security requirements for health record. This study will examine these requirements and propose a framework for healthcare cloud providers that will assist in securely storing and sharing of patient' data they host. It should also allow only legitimate users to access portion of the records' data they are permitted to. The focus will be on these precise security issues of cloud computing healthcare and how attribute-based encryption can assist in addressing healthcare regulatory requirements. The proposed attribute-based encryption guarantees authentication, data confidentiality, availability, and integrity in a multi-level hierarchical order. This will allow the healthcare provider to easily add/delete any access rule in any order, which is considered beneficial particularly in medical research field.

“…But the system is only designed for online access control. More recently, Akinyele et al [1] presented a system along with a mobile app for iPhone for secure offline access to EHRs. They constructed their scheme based on ABE (Key-Policy and Ciphertext-Policy versions) and they developped a corresponding software library to help the implementation.…”

Abstract. The issue of handling electronic health records have become paramount interest to the practitioners and security community, due to their sensitivity. In this paper, we propose a framework that enables medical practitioners to securely communicate among themselves to discuss health matters, and the patients can be rest assured that the information will only be made available to eligible medical practitioners. Specifically, we construct a new cryptographic primitive to enable File Sharing in Electronic Health Records (FSEHR). This primitive enables doctors to read the information sent by the hospital, or by any other individuals (such as patients' health records), when the doctors have their 'license' validated by that given hospital. We construct such a cryptographic primitive and capture its security requirements in a set of security models. Subsequently, we present a concrete scheme, which is proven selectively chosen-ciphertext security (CCA-1) secure under the Decisional Bilinear Diffie-Hellman Exponent (DBDHE) assumption and fully collusion resistant.

“…We could not compare our ABE scheme timings against [2], because this work only implements the decryption algorithm and it does not presents the exact timings. Table 6 reports the timings obtained when a 6-attribute policy is employed in the ABE protocol.…”

“…In [1], the authors advocate the use of affine coordinates could be more attractive than the projective ones when implementing pairings in constrained devices, whereas the software library of [13] reports the current record in the computation of a single asymmetric pairing at the 128, 224 and 320-bit security levels. As for the implementation of pairingbased protocols on mobile devices, the only work that we are aware of is [2], where the authors described the design of an attribute-based encryption scheme able to preserve the confidentiality of the medical electronic records generated within a hospital environment.…”

Abstract. In 2011, Waters presented a ciphertext-policy attribute-based encryption protocol that uses bilinear pairings to provide control access mechanisms, where the set of user's attributes is specified by means of a linear secret sharing scheme. Some of the applications foreseen for this protocol lie in the context of mobile devices such a smartphones and tablets, which in a majority of instances are powered by an ARM processor supporting the NEON vector set of instructions. In this paper we present the design of a software cryptographic library that implements a 127-bit security level attribute-based encryption scheme over mobile devices equipped with a 1.4GHz Exynos 4 Cortex-A9 processor and a developing board that hosts a 1.7 GHz Exynos 5 Cortex-A15 processor. For the latter platform and taking advantage of the inherent parallelism of the NEON vector instructions, our library computes a single optimal pairing over a Barreto-Naehrig curve approximately 2 times faster than the best timings previously reported on ARM platforms at this level of security. Further, using a 6-attribute access formula our library is able to encrypt/decrypt a text/ciphertext in less than 4.49mS and 15.67mS, respectively.
