III. GATEWAY SECURITY
The ALTA XL®Ethernet Gateway is designed and built to manage data from sensors
monitoring your environment and equipment securely. The same methods used by financial
institutions to transmit data are also used in the Monnit security infrastructure. The
gateway's security features tamper-proof network interfaces, data encryption, and
bank-grade security.
Monnit?s proprietary sensor protocol uses low transmit power and specialized radio
equipment to share application data. Packet-level encryption and verification are vital in
ensuring traffic isn?t altered between sensors and gateways. Paired with a best-in-class
range and power consumption protocol, all data is transmitted securely from your devices.
SENSOR COMMUNICATION SECURITY
Wireless devices listening on open communication protocols cannot eavesdrop on ALTA
Sensors. Monnit's sensor-to-gateway data communication implements Encrypt-RF®
encryption technology. This creates a secure wireless tunnel, generated using ECDH-256
(Elliptic Curve Diffie-Hellman) public key exchange to develop a unique symmetric key
between each pair of devices. Sensors and gateways use this link-specific key to process
packet-level data with hardware-accelerated 128-bit AES encryption. This minimizes power
consumption to optimize battery life. Thanks to this combination, Monnit offers robust
bank-grade security at every level.

DATA SECURITY ON THE GATEWAY
The ALTA XL®Ethernet Gateway prevents prying eyes from accessing the data stored on
the sensors. The gateway doesn't run on an off-the-shelf, multi-function operating system.
Instead, it runs on a purpose-specific, real-time embedded state machine that can't be
hacked to run malicious processes. There are also no active interface listeners that can be
used to gain access to the device over the network. The fortified gateway secures data
from attackers and protects the gateway from becoming a relay for malicious programs.

SERVER COMMUNICATION SECURITY
Communication between your ALTA XL®Ethernet Gateway and iMonnit is secured by
packet-level encryption. Similar to the security between the sensors and gateway, the
gateway and server also establish a unique key using ECDH-256 for encrypting data. The
packet-level data is encrypted end to end, removing additional requirements to configure
specialized cellular VPNs. The gateway can still operate within a VPN, if it is present.
