## Strengths and Weaknesses of Public-key Cryptography

Strengths and Weaknesses of Public-key Cryptography

Keys in public-key cryptography, **due to their unique nature**, are more computationally costly than their counterparts in secret-key cryptography. Asymmetric keys must be many times longer than keys in secret-cryptography in order to boast equivalent security [5].
