undo ah-new authentication-algorithm
View
IPSec proposal view & proposal view of crypto card
Parameter
md5-hmac-96: MD5 is adopted.
sha1-hmac-96: SHA1 is adopted.
Description
Using the ah-new authentication-algorithm command, you can configure the
authentication
authentication-algorithm command, you can restore the default value.
By default, MD5 is adopted.
This command is applicable to the IPSec module of the operating system and crypto
card.
AH does not have the encryption function, and is only responsible for packet
authentication.
HMAC algorithm uses encryption hashing function to authenticate the message, and
provides the integrity check based on the secret key. HMAC technology offers a
framework to insert various hashing function, such as SHA-1 and MD5, so as to
implement the data source authentication and the integrity protection, and to ensure
that the data in the transmission are not modified.
