Final answer:
The DTS-K is a system used to encrypt and decrypt sensitive data, ensuring confidentiality and integrity, especially where data security is critical.
Step-by-step explanation:
The DTS-K (Data Transformation Services - Keys) is a system used to encrypt and decrypt sensitive data. Encryption is the process of converting readable data into an encoded form that can only be read or accessed after it has been decrypted. Decryption is the reverse process, where encoded data is converted back into a readable form. The primary application of DTS-K is to ensure the confidentiality and integrity of data as it is transferred or stored, particularly in environments where data security is paramount, such as within government, military, or corporate contexts.
