Chosen-Ciphertext Secure RSA-Type Cryptosystems
This paper explains how to design fully secure RSA-type cryptosystems from schemes only secure against passive attacks, in the standard model. We rely on instance-independence assu...

When e-th Roots Become Easier Than Factoring
We show that computing e-th roots modulo n is easier than factoring n with currently known methods, given subexponential access to an oracle outputting the roots of numbers of the ...
