A Lightweight and Secured Certificate-Based Proxy Signcryption (CB-PS) Scheme for E-Prescription Systems

Abstract

Electronic prescription (E-prescription) is an emerging technology that allows health practitioners (doctors, physicians, pharmacists, or nurses) to electronically transmit prescriptions to pharmacies. E-prescription systems allow doctors to avoid traditional medical practices in which prescriptions are sent manually in handwritten form. Additionally, in cases in which a patient may not be able to collect the medication in person due to physical disabilities, the medications can be delivered to the patient's home directly. Furthermore, payments can also be made online (e.g., using credit cards or bank transfers). However, these distinctive features require a series of guidelines for the successful deployment of the E-prescription system due to stringent legal requirements and privacy regulations. Two major security requirements i.e. confidentiality and authentication need to be addressed. In general, the solution to ensuring confidentiality and authentication lies in the combination of both the encryption and digital signature functions in a single logic step called signcryption. Therefore, in this paper, we present a lightweight and provable secured certificate-based proxy signcryption (CB-PS) scheme for e-prescription systems. The formal security verification uses the Automated Validation of Internet Security Protocols and Applications (AVISPA) tool along with informal security analysis, which authenticates that the proposed CB-PS scheme can potentially be implemented in resource-constrained low-computing electronic devices in E-prescription systems.

The Rise of Cloud Computing: Data Protection, Privacy, and Open Research Challenges—A Systematic Literature Review (SLR)

“…The proposed scheme shows that besides security services, such as protection against attacks, confidentiality, integrity, nonblocking, nondisclosure, and confidentiality, accounting and communication costs are low compared to the current scheme. Document [ 154 ] gives the informal and formal security proof of the proposed scheme. Automated Validation of Internet Security Protocols and Applications (AVISPA) tool is used for formal security analysis, which confirms that the proposed CB-PS scheme can potentially be implemented for resource-constrained low-computing electronic devices in E-prescription systems.…”

An Access Control Scheme Using Heterogeneous Signcryption for IoT Environments

“…3, which clearly demonstrates our scheme's superiority in terms of communication costs. [19]. So, we first convert our scheme algorithm into H-L-P-S-L code which contains two main roles that are Sender and Receiver in which we used the public and private keys of sender and receiver.…”

“…To address this issue, we propose a new method called "Hyper Elliptic Curve Cryptography," or "HECC," which is a generalized form of ECC. It provides the same security level as RSA, Bilinear, and ECC, but with a smaller key, identity and certificate size of just 80 bits [19]. For energy-constrained devices, HECC is proved to be the most appropriate, cost-effective, and efficient scheme.…”

An Efficient Proxy Blind Signcryption Scheme for IoT

“…The group operations of addition and doubling of divisors is called a scalar multiplication divisor (SMD). The operations changed elliptic curve point multiplication into divisors of the Jacobian of a hyper ellipticcurve [53][54][55].…”

“…The computations of addition, subtraction, division and hash are ignored due to their fewer needs of computations and lower execution periods. For a more detailed illustration of the difference between the proposed and existing schemes, observations can be obtained from Ullah et al [55], and "test the runtime of basic cryptographic operations" respectively According to Ullah et al [55], 1 PM and 1 HM consume 0.97 and 0.48 milliseconds, respectively.
