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 …

Abstract Proxy Re-Encryption (PRE) is a useful cryptographic primitive that allows a data
owner to delegate the access rights of the encrypted data stored on a cloud storage system …

Identity-based encryption (IBE) eliminates the necessity of having a costly certificate
verification process. However, revocation remains as a daunting task in terms of ciphertext …

In this paper, for the first time, we define a general notion for proxy re-encryption (PRE),
which we call deterministic finite automata-based functional PRE (DFA-based FPRE) …

Conditional proxy re-encryption (CPRE) enables fine-grained delegation of decryption
rights, and has many real-world applications. In this paper, we present a ciphertext-policy …

Probabilistic public key encryption with equality test (PKEET), introduced by Yang et al. in
CT-RSA 2010, is able to check whether two ciphertexts are encryptions of the same …

Proxy re-encryption (PRE) is a highly useful cryptographic primitive whereby Alice and Bob
can endow a proxy with the capacity to change ciphertext recipients from Alice to Bob …

Since Cloud Service Provider is a semi-trusted party in cloud storage, to protect data from
being disclosed, users' data are encrypted before being uploaded to a cloud server …

We revisit the notion of proxy re-encryption (PRE PRE), an enhanced public-key encryption
primitive envisioned by Blaze et al.(E urocrypt'98) and formalized by Ateniese et …

Sharing digital medical records on public cloud storage via mobile devices facilitates
patients (doctors) to get (offer) medical treatment of high quality and efficiency. However …
