The need for authenticated encryption emerged from the observation that securely combining separate confidentiality and authentication block cipher operation modes could be error prone and difficult. This was confirmed by a number of practical attacks introduced into production protocols and applications by incorrect implementation, or lack of authentication (including SSL/TLS). WebA traditional way to achieve authenticity is to use Message Authentication Code (MAC): H K ( D) = T, where T is called tag .
