Cryptography during the French and American wars in Vietnam (P.1)

Does the history of cryptography during the French and American wars in Vietnam have any relevance to the concerns of people working in information security in the 21st century? The years 1945–1975 predate public key cryptography, predate DES, and hugely predate the internet. Nevertheless, there are several reasons why this story needs to be told in our time.

ZKP in Digital signature algorithm

Going from the vague (proving interaction without revealing knowledge - ZKP) to then applying it to do something specific (digital signature) is really interesting! What is too obvious may only have finite value, what is mysterious may have unlimited potential value.

ZKP

In this entry, I focus on explaining What is Zero-Knowledge Proof (ZKP) in the simplest way. Besides, I give many specific examples for you to understand the practicality of ZKP for technology products.
