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 کاملOn the McEliece Public-Key Cryptosystem
Based on an idea by Hin, the method of obtaining the original message after selecting k of n coordinates at random in the McEliece public-key cryptosystem is improved. The attack, which is more efficient than the attacks previously proposed, is characterized by a systematic method of checking and by a random bit swapping procedure. An optimization procedure similar to the one proposed by Lee an...
متن کاملWeak keys in the McEliece public-key cryptosystem
We show that it is possible to know whether the secret Goppa code of an instance of the McEliece public-key cryptosystem was chosen with a binary generator polynomial. Furthermore, whenever such a weak key is used, we present an attack which can be completed, for codes of length 1024 and dimension 524, with a large, but feasible amount of computation.
متن کاملA symmetric version of the McEliece public-key cryptosystem
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
متن کاملEnhancing the Security of the McEliece Public-Key Cryptosystem
Berson pointed out that the McEliece public-key cryptosystem suffers from two weaknesses: (1) failure to protect any message which is encrypted more than once; and (2) failure to protect any messages which have a known linear relationship with one another. In this paper, we propose some variants of the McEliece scheme to prevent Berson’s attacks. In addition, we also propose some secure and eff...
