摘要：
An encryption method encrypts a clear text twice using a first encryption engine to produce a first cipher text and a second encryption engine to produce a second cipher text. The method compares the first cipher text with the second cipher text, or compares a checksum of the first cipher text with a checksum of the second cipher text. If the comparison succeeds, the method transmits the data. In some embodiments, the method uses a first instance of an encryption key to produce the first cipher text and a second instance of the encryption key to produce the second cipher text.
