But instead of using chemicals, public key cryptography uses mathematical puzzles called trapdoor functions. These functions are easy to compute in one direction and extremely difficult to reverse.

Students and security engineers will appreciate this no-nonsense introduction to the hard mathematical problems used in cryptography and on which cybersecurity is built, as well as the overview of ...

If you work in regulated industries or with highly confidential systems, "quantum computing" has undoubtedly entered your ...

Find out more about available formats and browse any associated online resources. This book offers an accessible and engaging introduction to quantum cryptography, assuming no prior knowledge in ...

Peter Shor revolutionized public-key infrastructure (PKI) using concepts that trace back to 4,000-year-old Babylonian ...

Only Bitcoin should be considered cryptocurrency because PoW relies on cryptography and nothing else to secure the network. Reclaiming the name “crypto” is both powerful and important because it ...

A team of physicists has entangled three photons over a considerable distance, which could lead to more powerful quantum cryptography. Fifty years after the current internet was born, the physicist ...

PQC is a rapidly evolving technology, and preparing for its adoption requires keeping up with developments in several areas.

which would use a much faster symmetric-key cryptography scheme, where both parties have the means to decode and encode messages using the same private key. All the math aside, one does have to ...
