This is unarguably the BEST WPA3 video, and I have watched several!

I was lucky to be there to listen it live. I haven't found any better talk on those topics so far. Well done Hemant.

Thanks Hemant for wonderful sesseion on WPA3. Can someone please tell me, What is the size of g and p value? And, from where AP and STA would get these values? to generate public key. And, I see At 3:25, P value is not used in generating public key. is that correct?

37:00 does this mean that WPA3 can be added to a router with just a software upgrade?

@WR3ND 2 жыл бұрын

Probably all but the WiFi chip level encryption going to 192 bit, but this is unlikely as it is rolling out with AX (WiFi6), existing networks usually want stability and consistency, and router sellers want to sell new routers.

What is the logic behind 8 alphanumeric password key combination is 2^48 ? Can someone explain pls

@WR3ND 2 жыл бұрын

I'm not sure what alphabet, but in English 26 letters + 26 uppercase + 10 numbers = 62, so a 1 character password would be 1 of 62 possibilities, a 2 character password would be 1 of 62^2 possibilities, 3 characters 1 of 62^3, and so on. People don't often use a string of random numbers and case sensitive letters as passwords though, so this is why dictionary and brute force attacks can be upwards of 70% effective on average if an attacker is diligent enough. Something to keep in mind.

@@WR3ND just to complete log2(62^8)=47.6 ~ 48 bits of randomness. Same math as log2(62)*8.
