14

CSP14

The IPSec encryption key. Zeroized when

DRAM

 

 

 

 

 

IPSec session is terminated.

(plaintext)

 

 

 

 

 

 

 

15

CSP15

The IPSec authentication key. The

DRAM

 

 

 

 

 

zeroization is the same as above.

(plaintext)

 

 

 

 

 

 

 

16

CSP16

The RSA public key of the CA. The no

NVRAM

 

 

 

 

 

crypto ca trust <label> command

(plaintext)

 

 

 

 

 

invalidates the key and it frees the public key

 

 

 

 

 

 

 

 

label which in essence prevent use of the key.

 

 

 

 

 

 

 

 

This key does not need to be zeroized

 

 

 

 

 

 

 

 

because it is a public key.

 

 

 

 

 

 

 

 

 

 

17

CSP17

This key is a public key of the DNS server.

NVRAM

 

 

 

 

 

Zeroized using the same mechanism as

(plaintext)

 

 

 

 

 

above. The no crypto ca trust <label>

 

 

 

 

 

 

 

 

command invalidates the DNS server public

 

 

 

 

 

 

 

 

key and it frees the public key label which in

 

 

 

 

 

 

 

 

essence prevent use of that key. This label is

 

 

 

 

 

 

 

 

different from the label in the above key.

 

 

 

 

 

 

 

 

This key does not need to be zeroized

 

 

 

 

 

 

 

 

because it is a public key.

 

 

 

 

 

 

 

 

 

 

18

CSP18

The SSL session key. Zeroized when the SSL

DRAM

 

 

 

 

 

connection is terminated.

(plaintext)

 

 

 

 

 

 

 

19

CSP19

The ARAP key that is hardcoded in the

Flash

 

 

 

 

 

module binary image. This key can be

(plaintext)

 

 

 

 

 

deleted by erasing the Flash.

 

 

 

 

 

 

 

 

 

 

20

CSP20

This is an ARAP user password used as an

DRAM

 

 

 

 

 

authentication key. A function uses this key

(plaintext)

 

 

 

 

 

in a DES algorithm for authentication.

 

 

 

 

 

 

 

 

 

 

21

CSP21

The key used to encrypt values of the

NVRAM

 

 

 

 

 

configuration file. This key is zeroized when

(plaintext)

 

 

 

 

 

the no key config-keycommand is issued.

 

 

 

 

 

 

 

 

 

 

22

CSP22

This key is used by the router to authenticate

DRAM

 

 

 

 

 

itself to the peer. The router itself gets the

(plaintext)

 

 

 

 

 

password (that is used as this key) from the

 

 

 

 

 

 

 

 

AAA server and sends it onto the peer. The

 

 

 

 

 

 

 

 

password retrieved from the AAA server is

 

 

 

 

 

 

 

 

zeroized upon completion of the

 

 

 

 

 

 

 

 

authentication attempt.

 

 

 

 

 

 

 

 

 

 

23

CSP23

The RSA public key used in SSH. Zeroized

DRAM

 

 

 

 

 

after the termination of the SSH session.

(plaintext)

 

 

 

 

 

This key does not need to be zeroized

 

 

 

 

 

 

 

 

because it is a public key; However, it is

 

 

 

 

 

 

 

 

zeroized as mentioned here.

 

 

 

 

 

 

 

 

 

 

24

CSP24

The authentication key used in PPP. This key

DRAM

 

 

 

 

 

is in the DRAM and not zeroized at runtime.

(plaintext)

 

 

 

 

 

One can turn off the router to zeroize this key

 

 

 

 

 

 

 

 

because it is stored in DRAM.
