| 摘要 |
A present invention relates to a data authentication method and a device thereof, wherein the method includes the steps of: generating a first sequence of data words to send an interface; calculating a second sequence of multiple signature words; interleaving the first sequence to the second sequence so as to produce an interleaved sequence. Each given signature words among the interleaved sequences cumulatively signs the data words that are signed by a previous signature in the interleaved sequence and the data words located between the previous signature and the given signature. The interleaved sequence is transmitted over the interface. |
