Signature Schemes
Ștefania Loredana Niță, Marius Iulian Mihăilescu · Apress eBooks · 2024
In the real world, when a message needs to be authenticated by an individual, it is written on paper, and then the individual signs the message. Therefore, it is known that this specific message belongs to a specific person. In the digital world, things can happen similarly: a piece of data (message) is created by an individual, and then the message is signed digitally with a specific signature by that individual. Digital signatures are an important component of modern cryptography and cybersecurity, providing a way to verify the authenticity and integrity of digital messages or documents. They have an important role in different applications, from email security to software distribution and beyond.
