Recently, users have used open‐source intelligence (OSINT) to gather and obtain
information regarding the data of interest. The advantage of using data gathered by OSINT is …

This paper analyzes the secure access delegation problem, which occurs naturally in the
cloud, and postulate that Proxy Re-Encryption is a feasible cryptographic solution, both from …

Cloud computing has become prevalent due to its nature of massive storage and vast
computing capabilities. Ensuring a secure data sharing is critical to cloud applications …

Data sharing is an important functionality in cloud storage. In this paper, we show how to
securely, efficiently, and flexibly share data with others in cloud storage. We describe new …

Cloud-supported Internet of Things (Cloud-IoT) has been broadly deployed in smart grid
systems. The IoT front-ends are responsible for data acquisition and status supervision …

Cipher text-Policy Attribute-Based Proxy Re-Encryption (CP-ABPRE) extends the traditional
Proxy Re-Encryption (PRE) by allowing a semi-trusted proxy to transform a cipher text under …

Proxy re-encryption (PRE) allows a semi-trusted proxy to convert a ciphertext originally
intended for Alice into one encrypting the same plaintext for Bob. The proxy only needs a re …

In a proxy re-encryption scheme, a semi-trusted proxy can transform a ciphertext under
Alice's public key into another ciphertext that Bob can decrypt. However, the proxy cannot …

Abstract In 1998, Blaze, Bleumer, and Strauss proposed a cryptographic primitive called
proxy re-encryption, in which a proxy transforms–without seeing the corresponding plaintext …

In a proxy re-encryption system, a semi-trusted proxy can convert a ciphertext originally
intended for Alice into a ciphertext intended for Bob, without learning the underlying …
