Subject [jira] Commented: (DERBY-528) Support for DRDA Strong User ID and Password Substitute Authentication (USRSSBPWD) scheme
Date Thu, 15 Jun 2006 08:03:31 GMT
    [ http://issues.apache.org/jira/browse/DERBY-528?page=comments#action_12416300 ] 

Bernt M. Johnsen commented on DERBY-528:
----------------------------------------

At a first glance:
NetConnectionRequest.java has only whitespace changes and should not be part of the patch.
There's a lot of cosmetic whitespace changes in several of the files (makes it harder to review
the patch).

 In ClientBaseDataSource.getUpgradedSecurityMechanism you no longer support USRIDPWD. Is that
the case or have I missed something?

> This JIRA will add support for (DRDA) Strong User ID and Password Substitute Authentication
(USRSSBPWD) scheme in the network client/server driver layers.
> Current Derby DRDA network client  driver supports encrypted userid/password (EUSRIDPWD)
via the use of DH key-agreement protocol - however current Open Group DRDA specifications
imposes small prime and base generator values (256 bits) that prevents other JCE's  to be
used as java cryptography providers - typical minimum security requirements is usually of
1024 bits (512-bit absolute minimum) when using DH key-agreement protocol to generate a session
key.
> Strong User ID and Password Substitute Authentication (USRSSBPWD) is part of DRDA specifications
as another alternative to provide ciphered passwords across the wire.
> Support of USRSSBPWD authentication scheme will enable additional JCE's to  be used when
encrypted passwords are required across the wire.
> USRSSBPWD authentication scheme will be specified by a Derby network client user via
the securityMechanism property on the connection UR - A new property value such as ENCRYPTED_PASSWORD_SECURITY
will be defined in order to support this new (DRDA) authentication scheme.
