To expand on that idea a little.

DRM, at least modern DRM is based on the encryption. Essentially the book is encrypted, often for the specific reader you are using, and then the ebook reader (or in the case of B&N ereader DRM you) provides the decryption key which allows you to ultimately read the book.

Now, this also points out why DRM is never going to be effective at stopping pirates. The decryption key needs to be available to whoever purchased the book. Unless a company can completely hide the method of decryption (exceedingly unlikely) there is no way that a good programmer will not be able to develop a tool to permanently decrypt the ebook.
