The Sea & Chaos

I want to learn the docker to compile my environment. But this week I have no time to make full studying.

Thus, I make a record which made by Dalao-Zimablue in this post.

The competition was held in August.

The exercises except factor2 are done. And the article is mainly aim to make a record for myself. The Modus is about the multiplicative homomorphic system, which is similar to the Extended Euclidean algorithm.

List

• Modus
• rsa
• factor2
• secret_data

Wish I can solve out above.

1115-YD-GAME.

Write Up about crypto and misc.

AK the crypto~

Some import theorems which are suitable for applying to Cryptography.

At the same time, the post which is made as the record to note me that how to improve or deduction.

To conclude the functions that I met in these years.

Just show that how the functions and equations

make a one-to-one relation.

Relating to python, sagemath……

JUST conclude the attacks about RSA.

Make a record for myself.

The problem is mainly based on the backdoor. In RSA library, it has the CVE of CVE-2017-15361.In this case, we can calculate the prime which is likely random with the equation that:
$$
Prime = k \times M + (65537^{a} \mod M)
$$
It means that produce the list of primes and make them to collide， which satisfy the condition, thus output the target prime.

Also，the PKI system has different standards， we make some distinctions between different standards.

The article is used to record how to use hexo to build my own blog. I will try my best to make records by using English. To Be Honest, this is really somewhat a hard challenge for me.

The problems and some solutions are as follows.

Welcome to Hexo! This is your very first post. Check documentation for more info. If you get any problems when using Hexo, you can find the answer in troubleshooting or you can ask me on GitHub.
