In magic the gathering does shroud counter things such as, first strike, double strike, and indestructible?

i use eldrazi monument and true conviction in my white deck and my friend has a way to give all his creatures shroud and every time i attack him he says that my attacking creatures lose all its abilities such as life link, double strike, and indestructible because his blocking creatures have shroud. dose shroud really protect against things like that since necessarily they are not being targeted
