Practical Techniques for ACK Authentication in IEEE 802.15.4 Networks
Eun‐Kyung Ryu, Kee-Young Yoo · Applied Mathematics & Information Sciences · 2015
A secure acknowledgement (ACK) mechanism is essential to ensure reliable data transfer in wireless communication networks. However, because efficiency is the highest priori ty for resource-constrained settings, existing wireless s ecurity protocols tend to exclude integrity or confidentiality protection for ACK m essages. This limits the use of ACK mechanisms for reliable communication. In this paper we describe our schemes for supporting ACK authentication in 802.15.4 networks. Our schemes do not require a pre-setup phase for the sharing of additional secrets and introduce no additional computation or communication overhead. They are practical for use and directly applicable to the 802.15.4 standard.
