“…This helps the data owner achieve fine-grained delegation control. A recent scheme in [40] combined the concept of the PRE with certificate-based encryption and proposed a certificate-based PRE that helped resist the adaptive chosen ciphertext attack. Another proposed PRE scheme in [34] is based on a keyword search, in which the ciphertext is re-encrypted if it contains a keyword match with some information related to the reencryption key.…”

Fog computing is a promising paradigm that can mitigate the heavy burden on cloud-central processing of the vast amount of IoT data. Although fog computing has the advantages of low latency, storage, and computing resources that serve IoT applications and things, it hardly suffers from security and privacy challenges. Proxy re-encryption (PRE) is an effective cryptographic solution to ensure the security of fog-to-things communication. However, in PRE schemes, the problem of a processing delay caused by offloading significant computational load to the proxy for re-encryption, and the heavy computation operations of data owner encryption and user decryption due to asymmetric cryptographic use, are still unresolved in the literature. In this paper, we propose a hybrid proxy re-encryption scheme that combines lightweight symmetric and asymmetric encryption algorithms to establish secure communications in fogto-things computing. In the proposed scheme, the computational cost incurred by fog nodes to carry out the re-encryption process is highly efficient. Meanwhile, the scheme can reduce the encryption and decryption overheads for end-users with resource-constrained devices. Security and performance analyses are conducted, and the results indicate that our scheme is secure, highly efficient, and lightweight.

The document plays an important role in the development of cloud computing. The user obtains and shares information by the electronic document. It is rich in content and various in representations. But the challenge to security is also brought. For the secure requirement for document in cloud, firstly, we will propose a novel user-based document secure management mechanism which introduces the reencryption. The re-encrypted key will be generated according the access control conditions, so that the encryption of document creation will be combined with access control. Secondly, we will present the corresponding protocols and the implementation of the mechanism. Finally, the analysis of properties will be made.

Recently, a lot of researches focused on identity‐based encryption (IBE). The advantage of this scheme is that it can reduce the cost of the public key infrastructure by simplifying certificate management. Although IBE has its own innovations, one of its weaknesses is the key escrow problem. That is, the private key generator in IBE knows decryption keys for all identities and consequently can decrypt any ciphertexts. The certificate‐based encryption (CBE) scheme proposed in EUROCRYPT 2003 provides a solution for the key escrow problem by allowing the certification authority to possess a partial decryption key that comprises the full decryption key together with the user‐generated private key. In this paper, we propose new CBE schemes without pairing and prove them to be Indistinguishability under Chosen Ciphertext Attack secure in the random oracle model based on the hardness of the computational Diffie–Hellman problem. When compared with other CBE schemes, our schemes are significantly efficient in terms of performance, which makes our schemes suitable for computation‐limited node (e.g., sensor, wearable device) networks.
