After writing a blog post about making a self-awareness experiment with the word “challenge”, I received a follow-up email from someone asking how my experiment worked.
I created a protocol where I would respond to a challenge by typing in a word I would never write. And my goal was to write about an issue that was of some importance to me.
Challenge-handshake authentication protocol is a secure method of authenticating users of a site. If you’re a security blogger, you’ll know that it’s an important issue, and I think it should be of some interest to you. If you’re a security blogger, you might not know about challenge-handshake authentication protocol.
The challenge-handshake authentication protocol is a new authentication protocol, and it’s been designed to be secure by using a challenge-response protocol that is very similar to the HTTP authentication protocol. This is a protocol that is already implemented in websites like Facebook and Google. If you’re interested enough to create a protocol like this, you’re probably going to want to use HTTPS, but you’re not going to find that information in this article.
The challenge-handshake authentication protocol is based on the same concept as a one time password. The challenge-response protocol uses the HTTP authentication protocol, but with one difference. Instead of the HTTP authentication protocol, people are using a challenge-response protocol that uses SSL/TLS. SSL/TLS is the encryption protocol that we use in the modern web. It is what encrypts our traffic when we access our websites.
What this means is that people can use the same authentication method for multiple sites. This is much more user friendly than using a password, in that the user is not forced to remember a sequence of characters that are difficult to change, and is much more secure because the encryption is done in the clear on our end.
What’s nice about this is that people can use the same authentication method for multiple sites. This is much more user friendly than using a password, in that the user is not forced to remember a sequence of characters that are difficult to change, and is much more secure because the encryption is done in the clear on our end.
But there are a couple of problems here. One, the challenge-handshake protocol isn’t actually secure because it uses a password to encrypt the data, so if one site wants to steal our user’s password, they can. Two, if someone wants to hack into our sites, they can get in through the same authentication method that the user is using. So this is the kind of thing that makes you feel like you’re sitting in an airport with a bunch of other people watching a movie.
Even if the protocol was secure, the fact that we only have an hour or two to make sure we get this right, makes me feel like we’re getting something really special. I hope our authentication method is as good as it is because it would be a shame to let something go to waste.
What we have here is a cross-site scripting attack. There are a couple of ways that this could be done, but the easiest is if someone changes a cookie on one of your sites and sets it to point to a different IP. This would allow an attacker to bypass authentication.
