What you intend essentially corresponds to the two-clause BSD or the MIT license. Here is a good summary: https://opensource.stackexchange.com/questions/217/what-are-... Your statement "you are not granted legal authority ..." essentially means that you are the copyright owner and don't want to give away your copyright, but only give a license to others as explicitly stated; that's essentially the default in all jurisdictions I'm aware of, so you don't have to repeat it in your license. But if you're in US you might want to register your copyright.
