Final answer:
Cryptographic systems used for the electronic transmission of classified information must be approved by Government Authorities.
Step-by-step explanation:
Cryptographic systems used for the electronic transmission of classified information must be approved by Government Authorities. These government authorities are responsible for ensuring that the cryptographic systems used are secure and meet the necessary standards for protecting classified information.
For example, in the United States, the National Security Agency (NSA) is responsible for approving cryptographic systems for the transmission of classified information. The NSA performs rigorous testing and evaluation of these systems to ensure their effectiveness.
Other countries also have government authorities with similar responsibilities. In most cases, these authorities consist of experts in cryptography and information security.
