Based on nonstationarity measure, we design an electronic seal for matching by the random encryption method. The electronic seal contains time information, equipment information, content information and specific information. The electronic seal combines four parts of information into a sequence and is masked by strong noise. It is indeed an information sequence (Information plus strong noise sequences) with length of 1024. Since the nonstationarity measure is not affected by the noise distribution, the electronic seal can match with the electronic seal information security under the noise. Simulations indicate that the electronic seal achieves good performance in security, avoids key management and high match accuracy. It may have potential application in the field of information security such as authentication.

Key words: Electronic seal, Nonstationarity measure, Random encryption, Authentication
