Specifications

The BlackBerry Device Service stores a copy of the seed in a file. When the BlackBerry Device Service restarts, it reads
the seed from the file and uses the XOR function to compare the stored seed with the new seed.
7. Uses the DSA PRNG function to generate 256 pseudorandom bits for use with AES encryption
8. Uses the pseudorandom bits with AES encryption to generate the message key
For more information about the DSA PRNG function, see Federal Information Processing Standard - FIPS PUB 186-2.
Using a VPN with a device
If your organization’s environment includes VPNs, such as IPSec VPNs or SSL VPNs, you can configure a device to
authenticate with the VPN so that it can access your organization's network. A VPN provides an encrypted tunnel between
a device and your organization’s network.
A VPN solution consists of a VPN client on the device and a VPN concentrator. The device can use the VPN client to
authenticate with a VPN concentrator, which acts as the gateway to your organization's network. Each device includes a
built-in VPN client that supports several VPN concentrators. The VPN client on the device uses strong encryption to
authenticate itself with the VPN concentrator. It creates an encrypted tunnel between the device and VPN concentrator
that the device and your organization's network can use to communicate.
For more information about configuring VPN profiles, see the BlackBerry Device Service Advanced Administration Guide.

Protecting a connection between a device
and a work Wi-Fi network
A device can connect to work Wi-Fi networks that use the IEEE 802.11 standard. The IEEE 802.11i standard uses the IEEE
802.1X standard for authentication and key management to protect work Wi-Fi networks. The IEEE 802.11i standard
specifies that organizations must use the PSK protocol or the IEEE 802.1X standard as the access control method for Wi-Fi
networks.
For more information about protecting a work Wi-Fi network, see the documentation from your organization’s Wi-Fi solution
provider.
