Tiny Bytes: RSA
tldr RSA works by exploiting the fact we can’t easily factor 2 large prime numbers and group theory to make a trapdoor permutation, aka a function that turns x into y but y can’t easily be turned into x without a secret. However, implementing RSA gets tricky because there’s lots of subtle attacks.MathRSA takes advantage of the group Z^*_{n} (multiplicative group of integers modulo n). This is the non-negative integers less than n that have an inverse modulo n. 1 x 1 mod n = 1. 0 x int = 0 so ...

Hi, Did much more writing on RSA. Will finish soon. Bye, Lucas

Hey,
Another sick, late night. I want to quickly write about why I like privacy. To me there’s something really profound when we are able to make the digital world mimic the physical world. In the physical world I can talk with my friends and know someone else isn’t listening, pay someone cash without someone tracking it, and express myself without someone bringing it up years later. In the physical world, things can last only for moments then be completely forgotten.
But that’s not what got me started writing tonight. My desire for privacy also comes from a fear. A fear of surveillance. A fear of exploitation. A fear to express myself. I wanted to dive deeper into that fear.
A lack of privacy means a world of surveillance. Someone is watching all of my actions. In some ways this isn’t an issue. Just because someone knows what I am doing doesn’t mean anything unless it impacts me. BUT someone watching you, particularly at scale, always has an impact.
(again the idea of surveillance at scale is the scariest thought to me - governments without ).
Someone knowing everything about me means there’s a ton of ways they can exploit me. Targeted scams of course. Large companies trying to give me ads or sell me stuff fall into this category. If I am tracked everywhere online I can be specifically targeted. My behavior will be altered and I will buy more things. Sometime helpful, many times unnecessary. While ads can help me find things I want, I find the current structure very unnerving. I don’t have a say how they work and incentives more and more tracking.
If everything I say can be known to everyone I will naturally filter myself. While having a filter is good in some situations (e.g., a funeral), it is not good when I want to message my friends. Lots of dumb shit is said in private without a lot of thought. People experiment with how to express themselves in private. Taking that privacy away and adding fear that everything you do will be known will damper that expression.
(If I knew my mom would see and know everything I did I would act differently)
Some quick thoughts for the night.
ggs,
Lucas
