Abstract
A system for encrypting and verifying a data packet includes an encryptor (,), a decryptor (,), an error detector (,), and switch (,). A data packet with embedded error detection codes is encrypted by the encryptor (,), decrypted by the decryptor (,), and then the error detector (,) examines the embedded error detection codes to determine if the data packet has had errors introduced during the encryption/decryption process. When errors are detected, the switch (,) is opened to keep erroneous data from being transmitted.
