EncrypTight User Guide

multiple Policy Enforcement Points (PEPs) can use common keys, while a centralized platform assumes 
the function of renewing keys at pre-determined intervals.

In this system, you use ETEMS to configure the PEPs, Policy Manager (ETPM) to create and manage 
policies, and Key Management System (ETKMS) to generate keys and distribute keys and policies to the 
appropriate PEPs. The PEPs encrypt traffic according to the policies and keys that they receive. 

Using EncrypTight, you can create distributed key policies for the network topologies shown in 

Layer 3 IP topologies
Hub and Spoke 

In a hub and spoke network, a hub network communicates with the 

spoke networks and the spoke networks communicate only with the 

hub network.

Multicast 

In multicast transmission, one or more networks send unidirectional 

streams to a multicast network address. The multicast routers detect 

the multicast transmission, determine which nodes have joined the 

multicast network as destination networks, and duplicate the packet as 

needed to reach all multicast destination networks.

Point-to-point 

In a point-to-point network, one network sends and receives data to 

and from one other network.

Mesh 

In a mesh network, any network can send or receive data from any 

other network.

Layer 2 Ethernet topologies
Mesh 

For Ethernet, you can create policies for mesh networks. Note that if 

the network uses VLAN ID tags, you can also create policies for virtual 

point-to-point connections.
