To date, the growth of electronic personal data leads to a trend that data owners prefer to
remotely outsource their data to clouds for the enjoyment of the high-quality retrieval and …

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 …

White-box cryptography has attracted a growing interest from researchers in the last decade.
Several white-box implementations of standard block-ciphers (DES, AES) have been …

Proxy re-encryption (PRE) provides a promising solution for encrypted data sharing in public
cloud. When data owner Alice is going to share her encrypted data with data consumer Bob …

Abstract© The Institution of Engineering and Technology 2019. The modulus switching
technique has been used in some cryptographic applications as well as in cryptanalysis. For …

Abstract Proxy re-encryption (PRE), introduced by Blaze, Bleumer, and Strauss at
EUROCRYPT 98, offers delegation of decryption rights, ie, it securely enables the re …

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 …

Proxy re-encryption (PRE) allows a proxy with a re-encryption key to translate a ciphertext
intended for Alice (delegator) to another ciphertext intended for Bob (delegatee) without …

In this work we define multiple relaxations to the definition of correctness in secure
obfuscation. While still remaining meaningful, these relaxations provide ways to obfuscate …

The concept of proxy re-encryption (PRE) dates back to the work of Blaze, Bleumer, and
Strauss in 1998. PRE offers delegation of decryption rights, ie, it securely enables the re …
