Implementing RSA and Diffie-Hellman in university cybersecurity plans comes with some challenges.

1. Key Management:

• It can be hard to create and share keys safely.
• What to do: Provide regular training and have strong rules about how to manage keys.

2. Performance Issues:

• RSA can take a lot of computer power, which can slow down networks.
• What to do: Use a mix of different encryption methods to help everything run more smoothly.

3. Vulnerability to Attacks:

• If not done right, both RSA and Diffie-Hellman can be at risk of attacks.
• What to do: Do regular checks and follow the best methods to protect these systems from new threats.

In summary, even though using these methods can be tough, careful planning and steps can help reduce risks.
