Abstract

The goal of a secure communication protocol is to ensure the data integrity, data secrecy, authentication, and replay protection. Now, because of the low computational capability, tiny memory, and limited energy resources’, designing a secure sensor network communication protocol, is indeed a challenging task. In order to ensure data secrecy in wireless sensor networks (WSN), most of the existing state of the art solutions, are merely emphasized on the conventional encryption modes like CTR, CBC, etc. On the other hand, for offering data integrity, they need to rely upon a secure MAC. Therefore, to ensure both the privacy and integrity of the WSN data, they need to perform at least 2n block encryptions, where n represents the number of blocks. In this article, we propose a variant of the conventional CTR mode, called integrity-aware counter (IA-CTR) mode, which requires only n + 1 of block encryptions to ensure both the privacy and integrity of the WSN message on a single pass.
