Installing an NS-HTIM-GMG2A or
NS-HTIM-GMG2B encryption module
The NS-HTIM-GMG2A and NS-HTIM-GMG2B encryption modules are 1U high and each occupies
two interface module slots. They use the same installation procedure. The following procedure
installs an NS-HTIM-GMG2A encryption module.
To install an NS-HTIM-GMG2A encryption module:
1.
Face the rear panel of the device and identify the target slots.
2.
Use a Phillips screwdriver to loosen the captive screws on the filler panels and then remove the
filler panels from the slots.
Keep the removed filler panels secure.

3.
Open the ejector levers of the encryption module and then gently push the module into the slots
along the guide rails.
4.
Close the ejector levers. Make sure the module is seated securely in the slots.
5.
Use a Phillips screwdriver to fasten the captive screws on the module.

Functionalities
The encryption modules provide the following functionalities:
•
Generate 256-bit GM standard SM2 key pairs.
•
Use SM1 ECB and CBC modes to encrypt and decrypt data.
•
Use the SM2/RSA key pairs stored internally or imported externally as needed to digitally sign
and verify the requested data.
