## What are the potential vulnerabilities to elliptic curve cryptography?

There are several potential vulnerabilities to elliptic curve cryptography, including side-channel attacks and twist-security attacks. Both types aim to invalidate the ECC’s security for private keys.

## Can ECC be trusted?

ECC have had their current website, www.ecc-eu.com on the same domain name for many years. They also have been registered at Companies House for many years. They post their achievements on their website and for the amount of time ECC have been trading, these achievements are impressive.

**Why ECC is not widely used?**

ECC uses a finite field, so even though elliptical curves themselves are relatively new, most of the math involved in taking a discrete logarithm over the field is much older. In fact, most of the algorithms used are relatively minor variants of factoring algorithms.

### Is ECC 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.

### Is elliptic curve stronger than RSA?

The foremost benefit of ECC is that it’s simply stronger than RSA for key sizes in use today. The typical ECC key size of 256 bits is equivalent to a 3072-bit RSA key and 10,000 times stronger than a 2048-bit RSA key! To stay ahead of an attacker’s computing power, RSA keys must get longer.

**Why is ECC more secure?**

As ECC — by structure — is more secure compared to RSA because it offers optimal security with shorter key lengths. As a result, it requires a lesser load for network and computing power, which translates into a better user experience.

## Is elliptic curve better than RSA?

## Why ECC is better than RSA However why is it not widely used?

The biggest differentiator between ECC and RSA is key size compared to cryptographic strength. As you can see in the chart above, ECC is able to provide the same cryptographic strength as an RSA-based system with much smaller key sizes.
