Which one is better: elliptic curve cryptography or RSA Elliptic curve cryptography is probably better for most purposes, but not for everything. ECC's main advantage is that you can use smaller keys for the same level of security, especially at high levels of security (AES-256 ~ ECC-512 ~ RSA-15424). This is because of fancy algorithms for factoring like the Number Field Sieve. Smaller keys, ciphertexts and signatures. EC versus RSA Certificate Priority - Avi Networks The priority of ECC over RSA is not configurable. Vantage prefers EC instead of RSA due to EC’s significantly faster performance with handshake negotiation. On average, processing for ECC is about four times less CPU-intensive than for RSA. EC also tends to provide significantly higher security. Diffie-Hellman, RSA, DSA, ECC and ECDSA - Asymmetric Key Jan 10, 2019 public key - ECC vs RSA: how to compare key sizes

## Comparing differences between RSA and ECC Encryption

Elliptic curve cryptography is an alternative approach to public-key cryptography over the current RSA standard. RSA algorithm can be used for encryption and digital signing, while ECC can only be used for signing. The security of a key depends on its size and its algorithm. Some algorithms are … Understanding ECC (Elliptic Curve Cryptography) in 5 Minutes

One important consideration of the signature generation process is that some of the time for each algorithm is The most important difference in ECC from RSA is the key size compared with the cryptographic resistance. ECC provides the same cryptographic strength as the RSA-system, but with much smaller keys. For example, a 256-bit ECC key is the same as 3072-bit RSA key (which are 50% longer than the 2048-bit keys used today). ECC keys are better than RSA & DSA keys in that the algorithm is harder to break. So not only are ECC keys more future proof, you can also use smaller length keys (for instance a 256-bit ECC key is as secure as a 3248-bit RSA key). As with DSA it requires a good source of random numbers. If the source isn’t good then the private key can be
