As a variant of NTRU, the integer polynomial ring is replaced by two binary truncated polynomial rings GF(2)[x]/(xn+1). DBTRU has some advantages over NTRU in terms of security and performance. In this paper, we propose a polynomial-time linear algebra attack against the DBTRU cryptosystem, …

The idea behind McEliece public-key cryptosystem is based on the fact that the decoding problem of an arbitrary linear code is an NP-hard problem [2].The McEliece scheme has the
WebJan 26, 2024 · "Breaking a cryptosystem" means winning a GAME associated with the cryptosystem’s security. The game (i.e., algorithm) is played between an adversary and a challenger. Both adversary and challenger are computers who run probabilistic algorithms. The probability the adversary wins should be negligible relative to some target probability … WebProblem 3: Let Alice have an elliptic curve cryptosystem with parameters {p, a, b, P, n} = {11, 2, 4, (0, 2), 17}. Alice has private key d = 5 and public key Q = dP = (9, 5). Assume Alice wants to sign her signature on message m = 6 using ECDSA and then let Bob verify it. List all the steps and complete the calculation performed by Alice and by ...
