The 2621XM/2651XM Router

Figure 6

The tamper evidence seals are produced from a special thin gauge vinyl with self-adhesive backing. Any

attempt to open the router, remove Network Modules or WIC cards, or the front faceplate will damage

the tamper evidence seals or the painted surface and metal of the module cover. Since the tamper

evidence seals have non-repeated serial numbers, they may be inspected for damage and compared

against the applied serial numbers to verify that the module has not been tampered. Tamper evidence

seals can also be inspected for signs of tampering, which include the following: curled corners, bubbling,

crinkling, rips, tears, and slices. The word "OPEN" may appear if the label was peeled back.

Cryptographic Key Management

The router securely administers both cryptographic keys and other critical security parameters such as

passwords. The tamper evidence seals provide physical protection for all keys. All keys are also

protected by the password-protection on the Crypto Officer role login, and can be zeroized by the Crypto

Officer. Keys are exchanged manually and entered electronically via manual key exchange or Internet

Key Exchange (IKE).

The modules contain a cryptographic accelerator card (the AIM-VPN/EP), which provides DES (56-bit)

(only for legacy systems) and 3DES (168-bit) IPSec encryption at up to 15Mbps, MD5 and SHA-1

hashing, and has hardware support for DH and RSA key generation.

The module supports the following critical security parameters (CSPs):

Description

Name

CSP 1

This is the seed key for X9.31 PRNG. This key is stored in DRAM

and updated periodically after the generation of 400 bites; hence,

it is zeroized periodically. Also, the operator can turn off the

router to zeroize this key.

CSP 2

The private exponent used in Diffie-Hellman (DH) exchange.

Zeroized after DH shared secret has been generated.

CSP 3

The shared secret within IKE exchange. Zeroized when IKE

session is terminated.
