WebWe first introduce the notion of Randomized Functional Encryption RFE, a generalization of Functional Encryption dealing with randomized functionalities of interest in its own right, and show how to construct an RFE from a standard semantically secure FE. Web1 Oct 2014 · Specifically, we show that our definitions have the following properties: Usefulness: Securely obfuscating (the encryption function of) a secure private-key encryption scheme yields a secure ...
Securely Obfuscating Re-Encryption Journal of Cryptology
WebCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We present a positive obfuscation result for a traditional cryptographic functionality. This positive result stands in contrast to well-known impossibility results [3] for general obfuscation and recent impossibility and improbability [13] results for obfuscation of many cryptographic … Web24 Aug 2012 · Encryption involves storing some secret data, and the security of the secret data depends on keeping a separate "key" safe from the bad guys. Obfuscation is hiding … genetic modified organisms examples
Lattice-based obfuscation for re-encryption functions
WebHohenberger et al. got a result of securely obfuscating re-encryption [20], which is the first positive result for obfuscating an encryption functionality and against a series of impossibility results [18, 16, 4]. Since the introduction of PRE by Blaze, Bleumer, and Strauss [6], there have been many papers [6, 21, 2, WebA facility operating in a first mobile communication device (MCD) is described. The facility generates a key pair made up of a private key and a public key for use by the first MCD in communicating with other MCDs. The public key has information content. The facility constructs a first public key component and a second public key component, that each … Web1.2 The Obfuscated Re-Encryption Scheme Comparison with Prior Work. Mambo and Okamoto [MO97] noted the pop-ularity of re-encryption programs in practical … genetic modifiers of thalassemia
