It is not currently possible to do this within Confluence. A workaround would be to set up a group mailing list for each group that you want to share with, and then share the page to that group email.
There is an open feature request to support sharing to groups: https://jira.atlassian.com/browse/CONF-22430
Watch that issue to stay informed on it's progress.
