In general, public key based encryption is much slower than symmetric key based encryptiona.Trueb.False

Analysis of the Statement

1. Understanding Encryption Types:

   • Public Key Encryption (Asymmetric Encryption): This involves a pair of keys, one public and one private. It is typically slower due to the complex mathematical computations involved in encryption and decryption.
   • Symmetric Key Encryption: This uses the same key for both encryption and decryption. It is generally faster as it involves simpler algorithms.

2. Comparison:

   • Public key encryption is intended for secure key exchange and smaller amounts of data, whereas symmetric encryption is suitable for encrypting larger data volumes.
   • Since public key algorithms require more computational resources, they are indeed slower compared to symmetric techniques.

Conclusion

Based on the analysis, the statement is true.
