“…In this scheme, the proxy can be used to verify the validity of the signature besides resigning, so that the user does not need to undertake the heavy burden of calculation. Then, Patonico et al [25] put forward an efficient proxy re-signcryption scheme using the arithmetic operation in the elliptic curve, so as to realize the safe ownership transfer in the cloud. Under the attention of quantum computers, in order to resist this kind of attack, some researchers [26,27] turned their direction to construct PRS schemes from the perspective of lattices.…”

The introduction of the electronic medical record (EHR) sharing system has made a great contribution to the management and sharing of healthcare data. Considering referral treatment for patients, the original signature needs to be converted into a re-signature that can be verified by the new organization. Proxy re-signature (PRS) can be applied to this scenario so that authenticity and nonrepudiation can still be insured for data. Unfortunately, the existing PRS schemes cannot realize forward and backward security. Therefore, this paper proposes the first PRS scheme that can provide key-insulated property, which can guarantee both the forward and backward security of the key. Although the leakage of the private key occurs at a certain moment, the forward and backward key will not be attacked. Thus, the purpose of key insulation is implemented. What's more, it can update different corresponding private keys in infinite time periods without changing the identity information of the user as the public key. Besides, the unforgeability of our scheme is proved based on the extended Computational Diffie-Hellman assumption in the random oracle model. Finally, the experimental simulation demonstrates that our scheme is feasible and in possession of promising properties.

A Multi-Message Multi-Receiver Signcryption Scheme with Edge Computing for Secure and Reliable Wireless Internet of Medical Things Communications

et al. 2021

Thanks to recent advancements in biomedical sensors, wireless networking technologies, and information networks, traditional healthcare methods are evolving into a new healthcare infrastructure known as the Internet of Medical Things (IoMT). It enables patients in remote areas to obtain preventative or proactive healthcare services at a cheaper cost through the ease of time-independent interaction. Despite the many benefits of IoMT, the ubiquitously linked devices offer significant security and privacy concerns for patient data. In the literature, several multi-message and multi-receiver signcryption schemes have been proposed that use traditional public-key cryptography, identity-based cryptography, or certificateless cryptography methods to securely transfer patient health-related data from a variety of biomedical sensors to healthcare professionals. However, certificate management, key escrow, and key distribution are all complications with these methods. Furthermore, in terms of IoMT performance and privacy requirements, they are impractical. This article aims to include edge computing into an IoMT with secure deployment employing a multi-message and multi-receiver signcryption scheme to address these issues. In the proposed method, certificate-based signcryption and hyperelliptic curve cryptography (HECC) have been coupled for excellent performance and security. The cost study confirms that the proposed scheme is better than the existing schemes in terms of computational and communication costs.
