“…The SHIB-PRE scheme [23] proposed a new concept for WSNs of proxy re-encryption of the source hidden identity, which supports the gateway in the wireless network to directly transfer the encrypted data of one user to another. The underlying plaintext data is disclosed throughout the sharing stage, but the agent must be a gateway or cloud.…”

Wireless sensor networks have become increasingly popular due to the rapid growth of the Internet of Things. As open wireless transmission mediums are easy to attack, security is one of the primary design concerns for wireless sensor networks. Current solutions consider routing and data encryption as two isolated issues, providing incomplete security. Therefore, in this paper we divide the WSN communication process into a data path selection phase and a data encryption phase. By proposing an improved transmission method based on ant colony optimization and threshold proxy re-encryption for wireless sensor networks,named as ACOTPRE, it resists internal and external attacks and ensures safe and efficient data transmission. In the data path selection stage, the ant colony optimization algorithm is used for network routing. The improvement of the pheromone concentration is proposed. In order to resist attacks from external attackers, proxy re-encryption is extended to WSN in the data encryption stage. The threshold secret sharing algorithm is introduced to generate a set of re-encryption key fragments composed of random numbers at the source node. We confirm the performance of our model via simulation studies.

“…In this scheme, the proxy, namely the cloud computing server, cannot acquire the underlying message. Moreover, a proxy re-encryption scheme enables transforming one’s ciphertext to another’s ciphertext to achieve information sharing without leaking user’s secret key [33,39,40].…”

A smart watch is a kind of emerging wearable device in the Internet of Things. The security and privacy problems are the main obstacles that hinder the wide deployment of smart watches. Existing security mechanisms do not achieve a balance between the privacy-preserving and data access control. In this paper, we propose a fine-grained privacy-preserving access control architecture for smart watches (FPAS). In FPAS, we leverage the identity-based authentication scheme to protect the devices from malicious connection and policy-based access control for data privacy preservation. The core policy of FPAS is two-fold: (1) utilizing a homomorphic and re-encrypted scheme to ensure that the ciphertext information can be correctly calculated; (2) dividing the data requester by different attributes to avoid unauthorized access. We present a concrete scheme based on the above prototype and analyze the security of the FPAS. The performance and evaluation demonstrate that the FPAS scheme is efficient, practical, and extensible.

“…Since the first scheme [2] proposed by Blaze et al in 1998, PRE has attracted much attention, and many schemes [3]- [11] with various features (as shown in Table 1) have been proposed. PRE has been widely used in encrypted email forwarding [2], [3], digital rights management [12], cloud data sharing [13], and other delegation occasions [14], [15]. Being consistent with the original intention of PRE, the existing schemes mainly focus on access authorization, including single-hop authorization or multi-hop (multi-use) authorization, unidi-rectional authorization or bidirectional authorization, public key-based authorization or identity-based authorization, conditional authorization or universal authorization.…”

Proxy re-encryption (PRE), with the unique ciphertext transformation ability, enables various ciphertext authorization applications to be implemented efficiently. However, most existing PRE schemes mainly focus on access authorization while ignoring the situation where the key needs to be changed and the ciphertext needs to be evolved, making the scheme's practicability and security inadequate. Moreover, the few schemes that simultaneously combine ciphertext authorization, key update, and ciphertext evolution are not satisfactory in terms of security. For solving this problem, based on Xiong et al.'s scheme, this paper proposes an improved revocable and identity-based conditional proxy re-encryption scheme with ciphertext evolution (RIB-CPRE-CE) for secure and efficient cloud data sharing. The proposed scheme inherits the characteristics of multi-use, constant ciphertext length, fine-grained authorization, collisionresistance security, and chosen ciphertext attack (CCA) security from the original method. Also, it supports updating ciphertext to adapt to the new key after changing the identity (key) or achieves authorization revocation by evolving ciphertext. Two new algorithms, URKeyGen and UpReEnc, have been integrated into the original delegation scheme to support ciphertext evolution. The formal definition, security model, concrete construction, and security analysis of RIB-CPRE-CE have been presented. The comparison and analysis show that the proposed scheme is practical and secure. Although it adds a ciphertext evolution function for supporting key update and delegation revocation, its efficiency and security are not reduced. The proposed scheme can also be used in other access authorization systems that need to change the key or revoke the authorization. It has certain practicability and security.
