Configuration of Encryption Using IPsec

Configuration of Encryption Using IPsec
When setting [Authenticate by Digital Signature] for [IKE Authentication Method] to make
IPsec communication, register a certificate with the device. No certificate is registered with
the device by factory default. Import an IPsec certificate. After importing a certificate,
configure IPsec.
When the IKE authentication method is set to [Authenticate by Preshared Key], skip the
step 1 "Certificate Arrangement" and go to step 2 "Configuration of IPsec".
For information on IKE authentication methods, refer to "[IPsec Settings]" (P.160).
You cannot import a certificate that already has been registered either as [Device Certificates] or [Other
Certificates]. Delete the registered certificate beforehand.
If a certificate to be imported as an IPsec certificate contains V3 extension "KeyUsage", "digitalSignature" bit
must be asserted.
Step1 Certificate Arrangement
To configure a certificate using CentreWare Internet Services, configure the encryption
settings for HTTP communications, and then import a certificate issued by another CA to
use it for the IPsec certificate.
You cannot use a self-signed certificate created with CentreWare Internet Services for IPsec.
The public key of the certificate that can be imported to the device shall be either of RSA
®
public key (up to
4096 bits) and ECC public key P-256/P-384/P-521.
For details on how to configure the encryption settings for HTTP communication, refer to "Configuration of
HTTP Communications Encryption" (P.183).
