  • generating a device key and a buffer server key from a corporate server key, comprising;

    extracting a first split password and a second split password from an encrypted version of the corporate server key;

    encrypting the first split password with the second split password to produce the buffer server key; and

    encrypting the second split password to produce the device key, wherein the device key is stored on a mobile device and the buffer server key is stored on the buffer server;

    receiving, by the buffer server, a first communication request and the device key from the mobile device, wherein the buffer server comprises a processing unit and a storage device;

    verifying the device key and the buffer server key, wherein the device key and the buffer server key are related;

    sending, to a corporate server, a request with details associated with the device key and the buffer server key;

    receiving a response from the corporate server;

    removing, by the buffer server, less than all data from the response from the corporate server before forwarding a reduced response to the mobile device, wherein the reduced response comprises only predetermined fields in accordance with a corporate policy;
