Practical Threshold RSA Signatures without a Trusted Dealer
We propose a threshold RSA scheme which is as efficient as the fastest previous threshold RSA scheme (by Shoup), but where two assumptions needed in Shoup’s and in previous schem...

How Secure Are Elliptic Curves over Composite Extension Fields?
We compare the method of Weil descent for solving the ECDLP, over extensions fields of composite degree in characteristic two, against the standard method of parallelised Pollard ...

Bias in the LEVIATHAN Stream Cipher
We show two methods of distinguishing the LEVIATHAN stream cipher from a random stream using 236 bytes of output and proportional effort; both arise from compression within the ci...
