What are the advantages and disadvantages of key management protocol ?

Photo of author

By Dipali Umre

Advantages:

  1. Storage Efficiency:
    • Advantage: It saves storage space by requiring less than N – 1 keys to be stored.
  2. Scalability:
    • Advantage: The system can easily grow or handle a larger number of users or devices.

Disadvantages:

  1. Authentication and Revocation Issues:
    • Disadvantage: It lacks a clear authentication process and doesn’t define a proper way to revoke or refresh keys.
  2. No Dynamic Handshaking for Data Aggregation:
    • Disadvantage: The dynamic handshaking process hinders the ability to aggregate data efficiently.
  3. Lack of Support for Collaborative Operations:
    • Disadvantage: It doesn’t support collaborative operations, making it challenging for multiple entities to work together seamlessly.
  4. Unreliable Connectivity:
    • Disadvantage: Nodes may not have a common key with all neighbors, leading to potential communication issues if some nodes are unreachable.
  5. Security and Accessibility Concerns:
    • Disadvantage: Fails to meet security requirements, including authentication, and operational requirements like reliable accessibility.
