## What is elliptic curve cryptography?

Elliptic Curve Cryptography (ECC) is a key-based technique for encrypting data. ECC focuses on pairs of public and private keys for decryption and encryption of web traffic. ECC is frequently discussed in the context of the Rivest–Shamir–Adleman (RSA) cryptographic algorithm.

## How the elliptic curve can be used for cryptography?

Elliptic curve cryptography is now used in a wide variety of applications: the U.S. government uses it to protect internal communications, the Tor project uses it to help assure anonymity, it is the mechanism used to prove ownership of bitcoins, it provides signatures in Apple’s iMessage service, it is used to encrypt …

**Where is the elliptic curve used?**

Elliptic curves are applicable for encryption, digital signatures, pseudo-random generators and other tasks. They are also used in several integer factorization algorithms that have applications in cryptography, such as Lenstra elliptic-curve factorization.

### Which elliptic curve is used in Bitcoin?

Point Addition. The elliptic curve equation used in Bitcoin’s cryptography is called secp256k1 which uses this equation: y²=x³+7, a=0 b=7.

### How are ECC keys generated?

The key generation in the ECC cryptography is as simple as securely generating a random integer in certain range, so it is extremely fast. Any number within the range is valid ECC private key. The public keys in the ECC are EC points – pairs of integer coordinates {x, y}, laying on the curve.

**Why ECC is faster than RSA?**

Elliptic Curve Cryptography (ECC) provides an equivalent level of encryption strength as RSA (Rivest-Shamir-Adleman) algorithm with a shorter key length. As a result, the speed and security offered by an ECC certificate are higher than an RSA certificate for Public Key Infrastructure (PKI).

#### Is elliptic curve more secure than RSA?

ECC is more secure than RSA and is in its adaptive phase. Its usage is expected to scale up in the near future. RSA requires much bigger key lengths to implement encryption. ECC requires much shorter key lengths compared to RSA.
