Review of Lattice-based Public key Cryptography. (Russian)
This article presets a review of the achievements rapidly developing field of cryptography - public-key cryptography based on the lattice theory. Paper contains the necessary basic concepts and the major problems of the lattice theory, as well as together with the description on the benefits of this cryptography class - the properties of the reliability to quantum computers and full homomorphis...
متن کاملEfficient Public-Key Cryptography in the Presence of Key Leakage
We study the design of cryptographic primitives resistant to a large class of side-channel attacks, called“memory attacks”, where an attacker can repeatedly and adaptively learn information about the secret key,subject only to the constraint that the overall amount of such information is bounded by some parameter`. Although the study of such primitives was initiated only recentl...
متن کاملTowards efficient lattice-based cryptography
One essential quest in cryptography is the search for hard instances of a given computational problem that is known to be hard in the worst-case. In lattice cryptography we are in the unique situation that we have found a way of picking random instances which are at least as hard as well-studied lattice problems in the worst-case. At the same time, no attack running in subexponential time is kn...
متن کاملLattice Based Efficient Threshold Public Key Encryption Scheme
A (t,u)threshold public key encryption (TPKE) is a public key encryption where a private key is splitted among u decryption servers (insiders) and at least t decryption servers (insiders) are required to decrypt the ciphertext but no group of t− 1 or less malicious insiders can decrypt the message. Bendlin and Damgard [1] presented first lattice based threshold public key encryption scheme base...
متن کاملCryptography. key exchange, public key
General cryptographic schemes are presented where keys can be one-time or ephemeral. Processes for key exchange are derived. Public key cryptographic schemes based on the new systems are established. Authentication and signature schemes are easy to implement. The schemes may be integrated with error-correcting coding schemes so that encryption/coding and decryption/decoding may be done simultan...
