Outdoor wireless microwave Optix RTN380AX encoding 52451251 52451254

Overview of hardware security technology

Hardware security measures adopted by RTN 380AX:

L

Microwave interface: Adopting FEC encoding method and baseband time-domain adaptive equalizer, it has strong anti-interference ability

Force. The listener is unable to restore the content of the data frame without knowing both the encoding details and business configuration.

L

Modular design: Isolation between control units and business units, as well as between business units and business units. Any single

If a fault occurs in the element, it can be well isolated, minimizing the impact on other units of the system.

L

CPU flow control: To avoid excessive protocol packet impact on the CPU, the data flow sent to the CPU for processing

Classify and control the quantity. Ensure that the CPU can still function normally in the event of an attack.

L

Management interface control: The maintenance compartment protection cover is closed when the management interface is not in use to avoid illegal access.

Overview of Software Security Technology

The data processed by the device is divided into two categories: O&M management data and business data. Data on mutually independent physical channels

Transmit separately, independent of each other, and one type of data anomaly will not affect other types of data. Based on this business characteristic,

The equipment business can be divided into two planes:

L

Management plane

The management plane provides device access and device management functions. For example, account and password management for accessing devices, and device management

Communication protocol for networking, device alarm reporting, etc. The security features provided by the management plane can achieve the following:

Provide secure access, centralized management, and comprehensive security audits.

L

Data plane

The data plane is responsible for processing the business data flow entering the device, and forwarding business data packets based on hardware forwarding table entries

Row forwarding. Data plane security, firstly, prevents malicious theft, modification, deletion, etc. of user business messages,

Causing the confidentiality and integrity of user data to be compromised; The second is to ensure controllable hardware forwarding behavior and prevent forwarding

The table entries have been tampered with by malicious attacks, ensuring stable and reliable operation of the device forwarding plane.
