DSA is faster when generating a key than RSA. RSA on the other hand is faster at encryption than DSA. When decrypting, DSA is faster, mainly due to its great decryption capability. If you need digital signing, DSA is the encryption algorithm of choice. For verification of the digital signature RSA is the best choice.
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 Now let’s apply what we know about ECC vs. RSA: that RSA keys scale poorly compared to their ECC counterparts. As threats grow and keys need to be bigger, that’s more and more of a strain on your network. ECC, on the other hand, scales well and requires less resources in the first place. Oct 23, 2015 · Koblitz and Menezes also shoot down thinking that the NSA believes RSA-3072, the RSA alternative to ECC 256 and ECC 384, is more resistant to advances in quantum computing. May 26, 2016 · RSA 2048 bit vs ECC 256 bit Benchmarks Example tested on 512MB KVM RamNode VPS with 2 cpu cores with Centmin Mod Nginx web stack installed. ECC 256 bit (ECDSA) sign per seconds 6,453 sign/s vs RSA 2048 bit (RSA) 610 sign/s = ECC 256 bit is 10.5x times faster than RSA. RSA vs. ECC Comparison for Embedded Systems Introduction Author: Kerry Maletsky Modern cryptographic protocols increasingly use asymmetric algorithms such as RSA and ECC because of their flexibility and enhanced ability to manage keys. Developed in the late ‘70s, the Rivest, Shamir and Adelman algorithm

The Big Debate, 2048 vs. 4096, Yubico’s Position | Yubico Key lengths for these kinds of algorithms are considerably smaller. According to NIST, 112 and 128 bits of security, (equivalent to RSA-2048 and RSA-4096) correspond to 255-bit and 383-bit long ECC keys (worst case, even less on some specific curves). So why are we not using this everywhere? Key size - Wikipedia In cryptography, key size or key length is the number of bits in a key used by a cryptographic algorithm (such as a cipher).. Key length defines the upper-bound on an algorithm's security (i.e. a logarithmic measure of the fastest known attack against an algorithm), since the security of all algorithms can be violated by brute-force attacks.Ideally, the lower-bound on an algorithm's security

Performance Comparison of Elliptic Curves and RSA Signatures: Page 7 Signature verification is where RSA pulls ahead of ECC in performance. The time to verify a message signed in RSA is negligible for the key lengths used, and does not even show a difference until you go from 7680 to 15360 bits.
