IPFS is a protocol that dictates how it's clients are supposed to validate the data. If you use any of the client libraries they will do this for you (go-ipfs/js-ipfs). If you want to use cloudflare to distribute your index, you need to trust them to use a valid client implementation. Otherwise you can serve an index file off of your own server/network and distribute the rest of the assets via IPFS.
