Certified in Risk and Information Systems Control (CRISC) Practice Test

Hybrid cryptography combines the strengths of both symmetric and asymmetric encryption to achieve a balance of speed and security. This method typically involves using asymmetric cryptography to securely exchange a symmetric key. Once the symmetric key is shared, it can be used for rapid encryption and decryption of data because symmetric algorithms are generally faster than asymmetric ones for handling large amounts of data.

This blend allows systems to benefit from the secure key distribution associated with asymmetric cryptography while also leveraging the efficiency of symmetric encryption for data transmission. This is particularly useful in environments where both confidentiality and performance are critical. The choice to use both types of cryptographic techniques facilitates enhanced security measures, as it protects against potential vulnerabilities inherent in relying on just one method.

Other options do not accurately reflect the advantages of hybrid cryptography. For instance, the exclusive use of asymmetric keys, which may offer security, does not address speed concerns adequately. Additionally, hybrid cryptography can work with or without public key infrastructure, depending on the implementation. Lastly, relying solely on symmetric keys does not leverage the benefits of key exchange and secure communication that hybrid strategies achieve.
