Does the key sizes specified in Australia's ASD Approved Cryptographic Algorithms impact operational performance?
The larger the key size the slower the operational performance. Is it true?
The set of ASD Approved Cryptographic Algorithms can be found below:
- Diffie-Hellman (DH) for agreeing on encryption session keys
- Digital Signature Algorithm (DSA) for digital signatures
- Elliptic Curve Diffie-Hellman (ECDH) for key exchange
- Elliptic Curve Digital Signature Algorithm (ECDSA) for digital signatures
- Rivest-Shamir-Adleman (RSA) for digital signatures and passing encryption session keys or similar keys
