Public Key Encryption for the Forgetful
We investigate public key encryption that allows the originator of a ciphertext to retrieve a “forgotten” plaintext from the ciphertext. This type of public key encryption wit...

Identity-Based Decryption
Identity-based decryption is an alternative to identity-based encryption, in which Alice encrypts a symmetric key for Bob under a trusted authority’s public key. Alice sends Bob...

Storing Secrets on Continually Leaky Devices
We consider the question of how to store a value secretly on devices that continually leak information about their internal state to an external attacker. If the secret value is s...

Fully Homomorphic SIMD Operations
At PKC 2010 Smart and Vercauteren presented a variant of Gentry’s fully homomorphic public key encryption scheme and mentioned that the scheme could support SIMD style operations...

Public Key Locally Decodable Codes with Short Keys
This work considers locally decodable codes in the computationally bounded channel model. The computationally bounded channel model, introduced by Lipton in 1994, views the channe...

Realizing Stateful Public Key Encryption in Wireless Sensor Network
In this paper, we present our implementation of a stateful public key encryption (stateful PKE) scheme in the wireless sensor network (WSN) environment. In order to reduce the com...

Public Key Encryption and Encryption Emulation Attacks
The main purpose of this paper is to show that public key encryption can be secure against the "encryption emulation" attack (on the sender's encryption) by computat...

Efficient Chosen Ciphertext Secure Public Key Encryption under the Computational Diffie-Hellman Assumption
Recently Cash, Kiltz, and Shoup [20] showed a variant of the Cramer-Shoup (CS) public key encryption (PKE) scheme [21] whose chosen-ciphertext (CCA) security relies on the computa...
