A symmetric version of the McEliece public-key cryptosystem

چکیده
This article exploits the fact that linear codes can correct twice the number of erasures as that of errors, allowing reduction in code size and providing the same level of security. decryption or both. The large code size of McEliece

Quantum McEliece public-key cryptosystem
The McEliece cryptosystem is one of the best-known (classical) public-key cryptosystems, which is based on algebraic coding theory. In this paper, we present a quantum analogue of the classical McEliece cryptosystem. Our quantumMcEliece public-key cryptosystem is based on the theory of stabilizer codes and has the key generation, encryption and decryption algorithms similar to those in the clas...
متن کاملQTRU: quaternionic version of the NTRU public-key cryptosystems
In this paper we will construct a lattice-based public-key cryptosystem using non-commutative quaternion algebra, and since its lattice does not fully fit within Circular and Convolutional Modular Lattice (CCML), we prove it is arguably more secure than the existing lattice-based cryptosystems such as NTRU. As in NTRU, the proposed public-key cryptosystem relies for its inherent securi...
متن کاملStrengthening McEliece Cryptosystem
McEliece cryptosystem is a public-key cryptosystem based on error-correcting codes. It constitutes one of the few alternatives to cryptosystems relying on number theory. We present a modification of the McEliece cryptosystem which strengthens its security without increasing the size of the public key. We show that it is possible to use some properties of the automorphism groups of the codes to ...
متن کاملA note on quantum McEliece public-key cryptosystem
Inspired by Fujita’s analysis [Quantum inf. & comput. 12(3&4), 2012], we suggest a twice-encryption scheme to improve the security of the original quantum McEliece public-key encryption algorithm.
متن کاملLDPC Codes in the McEliece Cryptosystem: Attacks and Countermeasures
The McEliece cryptosystem is a public-key cryptosystem based on coding theory that has successfully resisted cryptanalysis for thirty years. The original version, based on Goppa codes, is able to guarantee a high level of security, and is faster than competing solutions, like RSA. Despite this, it has been rarely considered in practical applications, due to two major drawbacks: i) large size of...
