I've been busy build challenges for ACTF2019, and it's private so, there isn't anything.

I've been busy build challenges for ACTF2019, and it's private so, there isn't anything.

Due to visit of my friend, I spent a lot of time playing with him. It's so relaxing, so I'm not productive this weekend. :D

I've complete a linear cryptanalysis attack towards simple a toy SPN cipher, I feel very veryyyyy happy!

Today I've been reading A Tutorial on Linear and Differential Cryptanalysis and finally finish reading it. I've found more interesting stuff like The Amazing King - Linear Cryptanalysis Tutorial The Amazing King - Differential Cryptanalysis Tutorial

Still there will be only some casual notes.

Let's write some notes takes while challenging my self learning.

Change again.

I change challenges into challenging my self learning, so there will be my daily notes for what I've learn.

TBH I don't know if it's a good enough form as which to record it.

Let's try it~
