Chapter 1: Product description
Two levels of encryption are available to purchase:
•
128-bit: This allows an operator to encrypt all traffic sent over the wireless link using 128-bit
encryption.
•
256-bit: This allows an operator to encrypt traffic using either 128-bit or 256-bit encryption.
Encryption must be configured with the same size key in each direction.
AES encryption at the PTP 650 wireless port is based on pre-shared keys. An identical key must be
entered at each end of the link.
AES encryption for SNMPv3 or TLS is always based on a 128-bit key, regardless of level enabled in
the PTP 650 license key.
Critical security parameters
Critical security parameters (CSPs) are as follows:
•
Key of keys.
•
AES encryption keys for the wireless interface.
•
Private key for the HTTPS/TLS interface.
•
Entropy value for the HTTPS/TLS interface.
•
User account passwords for the web-based interface.
CSPs can be erased (zeroized) using the Zeroize CSPs page of the web-based interface or by
selecting the Zeroize CSPs option in Recovery mode.
Login information
PTP 650 optionally provides details of the most recent successful login, and the most recent
unsuccessful login attempt, for each user of the web-based interface.
Capability upgrades
ODUs are shipped with "Lite" data throughput capability, that is, up to 125 Mbps. Cambium
Networks supply capability upgrades to upgrade ODUs to "Mid" (up to 250 Mbps) or "Full" (up to
450 Mbps) capability. ODUs are shipped without AES encryption capability. Cambium Networks
supply capability upgrades to upgrade ODUs to128-bit or 256-bit AES Encryption.
Capability upgrades are purchased from Cambium and supplied as access keys. The user then
enters the access key into the PTP License Key Generator web page on the support website.
The License Key Generator creates a new license key and delivers it by email. The user then
installs the license key using the ODU web interface. License keys are bound to a single ODU and
are not transferrable.
