Intranet information communication mobile application system and application method thereof

The invention discloses an intranet information communication mobile application system and an application method thereof. The method comprises the steps that an information communication mobile application initiates service request data to a security interaction platform; the security interaction platform transmits the service request data to the mobile gateway by passing through the internal and external network isolation device through the external network data penetration module; the mobile gateway carries out bidirectional encryption and decryption on the service request data, carries out decryption and integrity verification after receiving an encryption request sent by the information communication mobile application, requests to be transmitted to the information communication service micro-application if the verification is passed, and returns response data; and the response data is encrypted again through the mobile gateway, passes through the internal and external network isolation device through th
