Summary
Chapter 4 describes modern encryption technologies in not-too-technical terms, from the building blocks of encryption primitives to more advanced technologies, within the debate of potential lawful access to encrypted digital evidence. It demonstrates that, in our modern world, there is no single kind of encryption and that a nuanced understanding of the technology needs to be kept in mind. It also presents several advanced encryption technologies that present additional security capabilities (beyond message encryption). After arguing against the deliberate creation of ‘back-doors’, it presents recent preliminary proposals of technological solutions to this issue.
