Convergent encryption, also known as content hash keying, is a cryptosystem that produces identical ciphertext from identical plaintext files. This has applications in cloud computing to remove duplicate files from storage without the provider having access to the encryption keys. The combination of deduplication and convergent encryption was described in a backup system patent filed by Stac Electronics in 1995. This combination has been used by Farsite, Permabit, Freenet, MojoNation, GNUnet, flud, and the Tahoe Least-Authority File Store. The system gained additional visibility in 2011 when cloud storage provider Bitcasa announced they were using convergent encryption to enable de-duplication of data in their cloud storage service.

Proof: Convergent Sequence is Bounded | Real Analysis
Any convergent sequence must be bounded. We'll prove this basic result about convergent sequences in today's lesson. We use the definition of the limit of a sequence, a useful equivalence involving absolute value inequalities, and then considering a maximum and minimum will help us find an

Convergent sequences are bounded
Convergent Sequences are Bounded In this video, I show that if a sequence is convergent, then it must be bounded, that is some part of it doesn't go to infinity. This is an important result that is used over and over again in analysis. Enjoy! Other examples of limits can be seen in the

Proof: Sequence (n+1)/n Converges to 1 | Real Analysis
We will prove the sequence (n+1)/n converges to 1. In other words, we're proving that the limit of (n+1)/n as n approaches infinity is 1. We use the epsilon definition of a convergent sequence and the proof is straightforward, following the typical form of a convergent sequence proof. Re

How does cryptography ACTUALLY work?
In this video I'll attempt to introduce you to some of the maths behind modern cryptography, which is in a sense how the world around us works now. Surprisingly, it has a lot to do with the simple ideas of division and remainders. We'll cover modular arithmetic basics, continued fractions

Proof: Absolute Value Theorem for Sequences | Real Analysis
We prove if the absolute value of a sequence converges to 0 then the original sequence does as well. So if (|a_n|) converges to 0 then (|a_n|) does as well. We go through two proofs of this, one using the definition of a convergent sequence and the other using the squeeze theorem. #RealAna
