- How do we send secret keys over the internet?
- How can we digitally sign electronic documents?
The answer lies in one-way trap door functions, which form the beginning of Public Key Cryptography.
We will explain how one-way trap-door functions are built in practice. These systems rely on classical number theory and they touch the boundary on what can be algebraically computed on computers. Nowadays one-way trap-door functions are implemented in all modern Web-browsers.
