Abstract: Multimedia internet keying protocol (MIKEY) aims at establishing secure credentials between two communicating entities. However, existing MIKEY modes fail to meet the requirements of low-power and low-processing devices. To address this issue, we combine two previously proposed approaches to introduce a new compressed and distributed MIKEY mode applied to a collaborative internet of things context. A set of third parties is used to discharge the constrained nodes from heavy computational operations. Doing so, the MIKEY pre-shared mode is used in the constrained part of network, while the public key mode is used in the unconstrained part of the network. Furthermore, to mitigate the communication cost we introduce a new header compression scheme that reduces the size of MIKEY's header from 12 bytes to 3 bytes in the best compression case. To assess our approach, we performed a detailed security analysis using a formal validation tool (i.e., Avispa). In addition, we performed an energy evaluation of both communicational and computational costs. The obtained results show that our proposed mode is energy preserving whereas its security properties are preserved untouched.
