WCF Security options for my scenario

I need to secure a WCF service and have the following limitations

1. Can use HTTPS
2. Must use basicHttpBinding
3. Must use custom username and password. No windows domain credentials or ASPNET membership i开发者_StackOverflow中文版s available.

Can you please let me if/how this can be done?

Thanks
