| Symmetric Cryptography# | Elliptic Curve Cryptography-based (ECC) scheme | RSA# /DSA |
|---|---|---|
| 56 | 112 | 512 |
| 80 | 160 | 1024 |
| 112 | 224 | 2048 |

Note: Symmetric Cryptography is in the unit key size in bit, ECC-based scheme is in size of \(n\) in bits, and RSA/DSA is in modulus size in bits.
As we can see from the above table, for Asymmetric Cryptography# to achieve the same security level as Symmetric Cryptography, it needs larger bits or key sizes. However, without stating the key sizes, it is rather hard to compare the security between two schemes.
