8. symbology and cryptography, I applied my 20-plus years of computer programming and research
9. The use of a PKI makes it possible to transmit authentication data across a Windows network with greater security than clear-text authentication mechanisms like that of FTP or even other secret key cryptography mechanisms
10. Here is the signature, created with the fancy-pants cryptography we’ve been discussing:
11. Chaum studied problems in cryptography while completing his PhD at the University of California, Berkeley, and was particularly interested in ways people could transfer money digitally and anonymously
12. Written under the pseudonym Satoshi Nakamoto and distributed on a cryptography mailing list in October 2008, a paper titled “Bitcoin: A peer-to-peer electronic cash system” was the first public mention of Bitcoin
13. Recently, two well-known cryptocurrency developers and entrepreneurs, Adam Back and Austin Hill, have suggested that the value of new cryptocurrencies could be directly linked one-to-one with the value of a bitcoin by using cryptography to allow coins to “ jump” between block-chains using clever algorithms
14. Every armored van, security officer, and bank vault that is used to protect traditional currency uses resources, and if we moved to a currency that leverages modern cryptography for security, many of these traditional security mechanisms that physically deter thieves from accessing this money may in theory no longer be necessary
15. Bitcoin relies on cryptography to function, which is why it is sometimes called a cryptocurrency
16. 1 But what role does cryptography play in Bitcoin, and why is it needed? We’ll begin with a short introduction to some necessary cryptography concepts (if they are familiar to you, you can just skip to “The Reasons Bitcoin Needs Cryptography” on page 137), and then we’ll explore the specific cryptographic methods used in Bitcoin
17. If you flipped to this chapter only because you wanted to know whether the cryptography used by Bitcoin is safe, you can rest easy knowing that Bitcoin uses only tried-and-tested cryptographic techniques: All of the cryptographic methods used by Bitcoin have been widely used in the past by governments and major corporations to secure financial, medical, and other sensitive information, as well as personal identification data
18. In fact, the cryptography in Bitcoin could be described as boring, simply because it relies on very conservative cryptographic algorithms
19. But in some fields of study, such as accounting and dentistry, boring is good; in the case of Bitcoin, conservative and well-established cryptography helps make it more secure
20. The interesting part is what Bitcoin does with cryptography
21. Historically, cryptography was used to send secret messages when necessary to protect information
22. With the advent of computers, which could do in milliseconds what used to take hours manually, cryptography is now used routinely by the masses to encrypt/decrypt very important (e
23. In addition to encrypting messages, modern cryptography is used to verify the validity of information (through cryptographic hash functions) and to prove one’s identity (through digital signatures)
24. For example, without modern cryptography, you wouldn’t be able to distinguish between two identical websites that both claimed to belong to your bank
25. Another one-way function, which is a bit more complicated but is commonly used in cryptography, involves the discrete logarithm
26. Let’s explore the functions of Bitcoin that require cryptography and then delve into the specific methods that Bitcoin uses
27. Public key cryptography is a high-level framework that can be implemented many different ways
28. For the remainder of this chapter, we’ll discuss the details of elliptical curve cryptography (ECC)
29. For a line, this addition process is very simple but is not useful for cryptography (and equally not useful for creating driving instructions for our “car” that are hard to reverse engineer)
30. Choosing different A and B points would lead to a different point C (Figure 7-4), which is the whole point of using this type of addition for cryptography: In the earlier jelly donut incident, Crowley had to drive a long, circuitous route back to his house so Satoshi’s home address would remain obscured
31. However, computers have limited memory, and it isn’t possible to use real-valued numbers as coordinates for points on the curve without introducing rounding errors (which are unacceptable in cryptography)
32. So how is it mathematically possible to generate new keys using only public key information? To explain, we’ll refer to the cryptography on how private keys and public keys are mathematically related
