Hi List! I was wondering if anybody could give me some pointers as to papers or books that discuss the advantages/disadvantages of computing an HMAC of a message versus previously computing a hash of the message and then calculating the HMAC of the hash. My initial thoughts are that there isn't any additional security provided by either method. What about calculating the HMAC of the message concatenated to the hash? This seems more secure but I have no idea how to prove either statement. Any helps is greatly appreciated.
