Noncommutative Polly Cracker-type cryptosystems and chosen-ciphertext security
Chosen-ciphertext attacks noncommutative Polly Cracker cryptosystems polynomial-based cryptography
2009/6/10
In this paper we consider chosen-ciphertext attacks against noncommutative
Polly Cracker-type cryptosystems. We present several
versions of these attacks, as well as techniques to counter them. Firs...

Countering chosen-ciphertext attacks noncommutative polly cracker-type cryptosystems
2009/3/9
In [2], Stanislav Bulygin presents a chosen-ciphertext attack against
certain instances of noncommutative polly cracker-type cryptosystems which
were proposed in [7] and [9]. In this article, we pre...
