Which one is better among public key cryptography key exchange and Zero-knowledge password proof? Which one is more popular, powerful or useful? Which one is used more in daily life or products which are used quite often? Can you give me some good examples?
Fatty, Thank you for the articles and papers, but I was wondering if you could explain the differences in a short paragraph.....like providing a summary?! If that is possible then it is really helpful..... :)
How can you compare different functions? For each function there is a protocol, and one should not compare apples to oranges!
ZK password proof is for user authentication (this user knows the password without revealing it) suitable for user auth. to a server.
Key exchange is for the two parties to share a key privately for whatever they want to use it for, and they better authenticate themselves to prevent Man-in-the-Middle attacks.
Moti, you are absolutely right. It was my mistake that I asked the question in a wrong way. What I actually wanted to ask is which one is more popular in use and in which sector (wrt system/information security)??
We all know that key exchange is fairly popular and is used in most of the applications now a days. But is the ZK password proof popular as well? Where is it used now and what are its scopes in coming 10 years??
