| Abstract: | An implementation of confidential data communication under embedded Linux environment in ISDN is proposed in this paper.First,there are simple explanations of the general communication process of ISDN and AT command set.Then,the execution plan of confidential data communication based on AT command set in ISDN is presented.The application shows this method is able to transport encrypted data in ISDN through AT command set.Besides,other communication modules can be added to expand the business in order to meet the needs of different users. |
