Strengths and Limitations of Asymmetric Cryptography
Strengths:
- No Need for Pre-Shared Keys: Eliminates the challenge of securely sharing keys in advance, as only the public key needs to be distributed.
- High Security: The private key remains secret, reducing the risk of unauthorized access.
- Versatility: Supports both encryption and digital signature functionalities.
Limitations:
- Slower Performance: Asymmetric encryption algorithms are computationally intensive compared to symmetric encryption.
- Key Length: Requires larger key sizes to achieve comparable security to symmetric systems, leading to increased processing time and storage requirements.
- Private Key Security: The entire system’s security hinges on the secrecy of the private key. If compromised, the system is no longer secure.
