Reverse Public Key Encryption
Abstract. This exposition paper suggests a new low-bandwidth publickey encryption paradigm. The construction turns a weak form of key privacy into message privacy as follows: let E...

Leakage Resilient ElGamal Encryption
Blinding is a popular and well-known countermeasure to protect public-key cryptosystems against side-channel attacks. The high level idea is to randomize an exponentiation in order...

Plaintext Simulatability
We propose a new security class, called plaintext-simulatability, defined over the public-key encryption schemes. The notion of plaintext simulatability (denoted PS) is similar to ...

Circular-Secure Encryption from Decision Diffie-Hellman
We describe a public-key encryption system that remains secure even encrypting messages that depend on the secret keys in use. In particular, it remains secure under a "key cy...

Certificateless signcryption
Certificateless cryptography achieves the best of the two worlds: it inherits from identity-based techniques a solution to the certificate management problem in public-key encrypti...

Public-Key Cryptosystems from Lattice Reduction Problems
We present a new proposal for a trapdoor one-way function, from which we derive public-key encryption and digital signatures. The security of the new construction is based on the ...

Public-Key Encryption in the Bounded-Retrieval Model
We construct the first public-key encryption scheme in the Bounded-Retrieval Model (BRM), providing security against various forms of adversarial “key leakage” attacks. In th...

Cryptanalysis of the Public-Key Encryption Based on Braid Groups
At CRYPTO 2000, a new public-key encryption based on braid groups was introduced. This paper demonstrates how to solve its underlying problem using the Burau representation. By thi...
