Embodiments relate to systems for the distribution of payload in a secure manner. A server may receive a query from a device that includes a subscriber identifier. The server may determine, from confidential information stored, an association between the subscriber identifier and a public key of the device. The server may retrieve the public key of the device. The server may generate a data payload as a response to the query. The server may encrypt the data payload by a symmetric key that is generated randomly. The server may encrypt the symmetric key by the public key of the device. The server may transmit the data payload and the symmetric key that are encrypted to the device for the device to use a private key corresponding to the public key to decrypt the symmetric key and use the symmetric key to decrypt the data payload.
