= RSA signature
{c}
{title2=$s=m^d\pmod N$}

A signature based on private <RSA cryptosystem> exponentiation, with public exponentiation used for verification. Textbook $s=m^d\pmod N$ is multiplicatively forgeable; a secure scheme requires an appropriate encoding and message digest rather than raw message exponentiation.
