With today's technology, many applications rely on
the existence of small devices that can exchange information and form
communication networks. In a significant portion of such applications, the
confidentiality and integrity of the communicated messages are of particular
interest. In this work, we propose two novel techniques for authenticating
short encrypted messages that are directed to meet the requirements of mobile
and pervasive applications. By taking advantage of the fact that the message to
be authenticated must also be encrypted, we propose provably secure
authentication codes that are more efficient than any message authentication
code in the literature. The key idea behind the proposed techniques is to
utilize the security that the encryption algorithm can provide to design more
efficient authentication mechanisms, as opposed to using standalone
authentication primitives.
