Stateful publickey cryptosystems: How to encrypt with one 160bit exponentiation
 ACM CCS 06
, 2006
"... We show how to significantly speedup the encryption portion of some publickey cryptosystems by the simple expedient of allowing a sender to maintain state that is reused across different encryptions. In particular we present stateful versions of the DHIES and KurosawaDesmedt schemes that each us ..."

Breaking and Fixing the NeedhamSchroeder PublicKey Protocol using FDR
, 1996
"... In this paper we analyse the well known NeedhamSchroeder PublicKey Protocol using FDR, a refinement checker for CSP. We use FDR to discover an attack upon the protocol, which allows an intruder to impersonate another agent. We adapt the protocol, and then use FDR to show that the new protocol is s ..."

PublicKey Cryptosystems from Lattice Reduction Problems
, 1996
"... We present a new proposal for a trapdoor oneway function, from whichwe derive publickey encryption and digital signatures. The security of the new construction is based on the conjectured computational difficulty of latticereduction problems, providing a possible alternative to existing publicke ..."

A New PublicKey Cryptosystem
, 1997
"... This paper describes a new publickey cryptosystem where the ciphertext is obtained by multiplying the publickeys indexed by the message bits and the cleartext is recovered by factoring the ciphertext raised to a secret power. ..."

Quantum publickey cryptosystems
 in Proc. of CRYPT0 2000
, 2000
"... Abstract. This paper presents a new paradigm of cryptography, quantum publickey cryptosystems. In quantum publickey cryptosystems, all parties including senders, receivers and adversaries are modeled as quantum (probabilistic) polytime Turing (QPT) machines and only classical channels (i.e., no q ..."

concrete scheme for quantum publickey cryptosystems: a quantum publickey encryption scheme or quantum trapdoor oneway function. The security of our schemes is based on the computational assumption (over QPT machines) that a class of subsetsum problems is intractable against any QPT machine. Our scheme
IdentityBased Encryption from the Weil Pairing
, 2001
"... We propose a fully functional identitybased encryption scheme (IBE). The scheme has chosen ciphertext security in the random oracle model assuming an elliptic curve variant of the computational DiffieHellman problem. Our system is based on bilinear maps between groups. The Weil pairing on elliptic ..."

Publickey Cryptosystems Provably Secure against Chosen Ciphertext Attacks
 In Proc. of the 22nd STOC
, 1995
"... We show how to construct a publickey cryptosystem (as originally defined by Diffie and Hellman) secure against chosen ciphertext attacks, given a publickey cryptosystem secure against passive eavesdropping and a noninteractive zeroknowledge proof system in the shared string model. No such secure ..."

A New PublicKey Cryptosystem Based on Higher Residues

We introduce two versions of our scheme, one deterministic and the other probabilistic. The deterministic version is practically oriented: encryption amounts to a ..."
