What are the three keys involved in secure transmissions?

The correct answer, which identifies the three keys involved in secure transmissions, is TEK, KEK, and TSK. In secure communication, these keys serve specific purposes that enhance the overall security of the transmission process.

TEK stands for Traffic Encryption Key, which is used to encrypt the actual data being transmitted. This key is critical for ensuring that only authorized parties can decode and access the sensitive information being shared.

KEK, or Key Encryption Key, is used to encrypt the TEK itself. By encrypting the Traffic Encryption Key, it provides an additional layer of security, ensuring that even if someone intercepts the KEK, they would still need the appropriate methods or keys to decrypt the TEK and access the traffic encryption.

TSK, or Transmission Security Key, plays a vital role in ensuring the integrity and authenticity of the transmission. This key is essential for verifying that the data has not been tampered with during transmission.

Together, these keys work in harmony to establish a secure environment for data transmission, protecting against eavesdropping and unauthorized access. This level of security is crucial in any system that requires the exchange of sensitive or critical information.
