We got a cryptographic algorithm and computer implementation based on graph isomorphism. An isomorphism between two graphs is a bijection between their vertices that pre serves the edges. For a graph $...

In public key cryptography, Alice knows functions $f$ and its inverse $f^{-1}$. $f$ is public and $f^{-1}$ is secret. To sign a message $m$, she gives $(m,a=f^{-1}(m))$. To verify a signature, the ...
