A Decade of Lattice Cryptography
Lattice-based cryptography is the use of conjectured hard problems on point lattices in Rn as the foundation for secure cryptographic constructions. Attractive features of lattice cryptography include: apparent resistance to quantum attacks (in contrast with most number-theoretic cryptography), high asymptotic efficiency and parallelism, security under worst-case intractability assumptions, and...
متن کاملLattice-Based Cryptography
In this chapter we describe some of the recent progress in lattice-based cryptography. Lattice-based cryptographic constructions hold a great promise for post-quantum cryptography, as they enjoy very strong security proofs based on worst-case hardness, relatively efficient implementations, as well as great simplicity. In addition, lattice-based cryptography is believed to be secure against quan...
متن کاملLattice Gas Symmetric Cryptography
Lattice gas cellular automata (Lgca) are particular cellular automata that imitate the behavior of particles moving on a lattice. We used a particular set of Lgca rules, called hpp, to mix bits in data blocks and obtain a symmetric cryptographic algorithm. The encryption and decryption keys are the positions of perturbation sites on the lattice (walls). Basically, this paper presents an origina...
متن کاملThe Geometry of Lattice Cryptography
Lattice cryptography is one of the hottest and fastest moving areas in mathematical cryptography today. Interest in lattice cryptography is due to several concurring factors. On the theoretical side, lattice cryptography is supported by strong worst-case/average-case security guarantees. On the practical side, lattice cryptography has been shown to be very versatile, leading to an unprecedented...
متن کاملLattice Based Cryptography: A Global Improvement
We describe a general technique to simplify as well as to improve several lattice based cryptographic protocols. The technique is rather straightforward and is easily applied to the protocols, and gives both a simpler analysis and better performance than the original protocols. The improvement is global: the modiied protocols are simpler, faster, require less storage, use less bandwidth and nee...
