The Strength of (Encryption) Algorithm

How do you measure the strength of an encryption algorithm?

So far, I have not found a complete reference on this. There are some references and they refer to different things, such as randomness, avalanche effect, diffusion, or anything that is related to how different the output if the input or key is very similar.

Another issue that is important is the key space. The larger the key space and the more complex the algorithm (big Oh?), the more difficult an algorithm is broken by brute force attack.

Another lead says that you have to go through cryptanalysis to measure the strength of an encryption algorithm.

Anyway, I am still searching. Let me know if you have more references.

I think the securest method at this time is by combining between Your Own Encryption Algorithm Method-YOEAMe (make an encryption method by yourself) and the other most securest one which most used recently. But security level of YOEAMe will be depends on each people, the smarter people will have the more secure method. It's looked like a discrimination right? hahaha... but it's not.

Nb: YOEAMe is my own terminology, hehehe... what crazy I am.

Himbauan Kepada Hacker & Cracker Indonesia & Malaysia

Kepada Hacker & Cracker Indonesia & Malaysia,

Saya mengharapkan anda tidak melakukan penyerangan atau/dan pengrusakan situs-situs Indonesia dan Malaysia.

Saya mengerti bahwa akhir-akhir ini beberapa masalah di dunia nyata membuat kita kesal dan marah. Namun kekesalan tersebut sebaiknya tidak dilimpahkan ke dunia maya (cyberspace). Semestinya sebelum melakukan aksi yang berdampak negatif, kita bisa melakukan langkah-langkah positif seperti melakukan dialog (melalui email, mailing list, bulletin board, blog, dan media elektronik lainnya).

Kita harus ingat bahwa kita hidup bertetangga dan bersaudara. Yang namanya hidup bertetangga pasti mengalami perbedaan pendapat. Mari kita belajar bertetangga dengan baik.

Saya berharap agar kita yang hidup di dunia maya mencontohkan bagaimana kita menyelesaikan permasalahan dengan kepala dingin dan hati yang lapang, sehingga para pemimpin kita di dunia nyata dapat mencontoh penyelesaian damai. Mudah-mudahan mereka dapat lebih arif dan bijaksana da…

Books, books, books

A snapshot of stacks and shelves of books that I have to read. The stack on the right side is actually on a chair. You can't see the bottom of it. It's a mess. Actually, it shows that I read them.
