z/OS Communications Server: IP Messages Volume 2 (EZB, EZD)
SC27-3655-01

EZD1910I
FIPS140 support is enabled for the IKE daemon and no valid KeyExchangeOffers were found in KeyExchangeAction ( KEAname )

Explanation

This message is issued when the IKE daemon is enabled to support the Level 1 security requirements of Federal Information Processing Standard publication 140-2 (FIPS 140), and one or more KeyExchangeOffer objects were omitted from the specified KeyExchangeAction object. If the IKE daemon is enabled for FIPS 140, the daemon omits KeyExchangeOffer objects that use the DES, MD5, or AES_XCBC cryptographic algorithms, or Diffie-Hellman groups 1, 2, or 5 from any proposal it builds.

In the message text:
KEAname
The KeyExchangeAction name that is configured in the policy.

System action

The SA negotiation fails; the IKE daemon continues.

Operator response

Contact the system programmer.

System programmer response

If you want the IKE daemon to be enabled to support FIPS 140, ensure that at least one KeyExchangeOffer object exists in the specified KeyExchangeAction object that does not contain any of the following:
  • HowToEncrypt DES
  • HowToAuthMsgs MD5
  • HowToVerifyMsgs HMAC_MD5_96
  • HowToVerifyMsgs AES128_XCBC_96
  • PseudoRandomFunction HMAC_MD5
  • PseudoRandomFunction AES128_XCBC
  • DHGroup Group1, Group2, Group5

If you do not want to continue to have the IKE daemon enabled to support FIPS 140, then configure FIPS140 No on the IkeConfig statement in the IKED configuration file and restart the IKE daemon.

See the information about Policy Agent and policy applications in z/OS Communications Server: IP Configuration Reference for more information about configuring policy.
