Enterprise server for SCADA system with security interface
First Claim
1. A system for communication for a supervisory control and data acquisition (SCADA) system, the SCADA system comprising:
- (a) an enterprise server;
(b) an intelligent electronic device (RTU), wherein the RTU measures a physical process and stores data in a memory area for transmission;
(c) a communication software (AES) linking the enterprise server with the RTU;
(d) a configuration software (ARME) with which the RTU can be reconfigured;
(e) a configurable security interface integrated into the AES, wherein the configurable security interface comprises, an encryption software, wherein the encryption software;
i. encrypts data transmitted from the AES to RTU using the encryption software,ii. decrypts data received from the RTU by the AES using the encryption software,iii. authenticates that the RTU is authorized to transmit to the AES, andiv. authenticates that the AES is authorized to transmit to the RTU; and
(f) the SCADA system is configured to;
i. communicate a command from the enterprise server to the RTU via the AES, where in the command comprises;
1. an ARME command to configure the RTU, or2. an OPCMessanger command requesting the data from the RTU, wherein the data is stored,ii. communicate a command from the RTU to the AES;
wherein the command comprises,1. the data, or2. a request of the AES for further instructions,iii. permit the RTU to receive the data input and to store the data, andiv. transmit the data back from the RTU to the AES and the enterprise server.

Abstract
An embodiment of this invention is a system for communication for a supervisory control and data acquisition (SCADA) system. The SCADA system includes, an enterprise server, and an intelligent electronic device (RTU). The RTU measures a physical process and stores data in memory area for transmission. A communication software (AES) links the enterprise server with the RTU. The SCADA system includes a configuration software (ARME) with which a RTU can be reconfigured. A configurable security interface can be integrated into the AES, wherein the security interface includes, encrypting data from RTU and AES using an encryption software. The encryption software can be Transport layer security, Secure Socket Layer. An example of encryption usable in the invention can be model TECSEC of Vienna, Va. The encryption software authenticates communications between an authorized RTU and AES and is also available form TECSEC.
