Bitcoin elliptic curve cryptography

Put simply, cryptography allows information to be communicated and kept in secret. Cryptography is closely linked to the disciplines of cryptology and cryptanalysis. Under the umbrella of cryptography resides two main branches: Symmetric-key encryption is one of the oldest types of encryption and makes use of the same key to both encrypt and decipher sensitive information.

In order to read messages , the sender and receiver would need to know the secret key ahead of time. This is one of the weaknesses of symmetric encryption, in that the ability to share the one key in a secure channel is not always possible, a vulnerability that one cannot be exposed to within the Bitcoin Blockchain network. The bitcoin blockchain does not make use of symmetric encryption as all transactions are broadcast and can be seen by anyone. Public-key cryptography makes use of two types of keys, private and public.

Digital Signatures asymmetric cryptography: Digital signatures are a mathematical techniques used to validate the authenticity and integrity of a message, software, and digital software or in this case, transactions.

There are two main functionalities that are required from digital signatures, being:. Generates two keys, a private signing key which is not to be revealed to anyone, which is used to create your signature, and a public key which is used for verification purposes, which is going to be given to anyone on the network, of which they will use it to verify your signature.

Takes something that claims to be a valid signature and verifies that its correct. Below is some basic mathematics and concepts in order to refresh yourself with regards to the functionality of Elliptic-curve cryptography:.

Another important type of group is the cyclic group. Cryptography is the art and science of storing and communicating data securely among an antagonist agent who may or may not be actively trying to intersect the original data for malicious purposes.
