Computer Science – Encryption | e-Consult

Symmetric Encryption:

• Advantages:
• Speed: Generally much faster than asymmetric encryption. This makes it suitable for encrypting large amounts of data.
• Efficiency: Requires less computational power.
• Suitable for bulk encryption: Ideal for encrypting large files or streams of data.

• Disadvantages:
• Key Distribution: The biggest challenge is securely distributing the secret key to the sender and receiver. This is a vulnerable point as if the key is intercepted, the entire communication is compromised.
• Scalability: Managing keys for multiple parties can become complex.

Asymmetric Encryption:

• Advantages:
• Secure Key Exchange: Eliminates the need for a secure channel to exchange keys. The public key can be freely distributed.
• Digital Signatures: Can be used to verify the authenticity and integrity of a message.

• Disadvantages:
• Speed: Significantly slower than symmetric encryption.
• Computational Cost: Requires more processing power.
• Vulnerable to certain attacks: Susceptible to attacks if the private key is compromised.
