“…In our opinion, the presence of a robot to distribute key material is not a very realistic assumption. The schemes in [31], [32] are based on a key tree which results in communication and computation costs which linearly increase with the number of group members. Finally, in [33], a secure and efficient key management scheme is proposed for multicast communication based on Elliptic Curve Cryptography (ECC).…”

Fog architectures are currently present in many applications. Constrained devices equipped with sensors produce measurements that will be sent to a nearby gateway, called the fog. The fog verifies, aggregates and forwards them to the server. Group authentication among these devices allows them to securely accept messages of the group members, resulting in faster updates in their process. When defining a security scheme, it should be considered that edge and fog devices are susceptible to attacks. Privacy of the devices should be guaranteed, with respect to outsiders and the fog. It should be impossible to track the connection pattern of devices with different fogs, even if several fogs are captured by an attacker. Inclusion of protection against potentially malicious fogs has not yet been considered in literature, especially not for group-based communications. We present a server-controlled group authentication and key agreement scheme, executed by the fog in collaboration with the devices that it can reach. The server, assumed to be fully trusted, is responsible for the registration and authorisation of the devices and initiates the key update process, whereas the fog takes care of the secure distribution process among its members. At the end, all entities in the group are ensured to possess the correct group key. Moreover, a pairwise secret key between device and server is obtained during the process. The proposed scheme is very efficient as it relies on elliptic curve cryptography and Lagrange interpolation. No initially shared secret key material among the entities needs to be pre-stored.

“…However, the schemes of [16,17] are using asymmetric-key-based methods as the basis of their key establishment system. The scheme in [16] is based on the Merkle identity tree. With this scheme, the direct and secure communications between any subgroup can be implemented and the delay of communication is decreased, making the scheme more suitable for WSNs.…”

This paper presents a new key management protocol for group-based communications in non-hierarchical wireless sensor networks (WSNs), applied on a recently proposed IP-based multicast protocol. Confidentiality, integrity, and authentication are established, using solely symmetric-key-based operations. The protocol features a cloud-based network multicast manager (NMM), which can create, control, and authenticate groups in the WSN, but is not able to derive the actual constructed group key. Three main phases are distinguished in the protocol. First, in the registration phase, the motes register to the group by sending a request to the NMM. Second, the members of the group calculate the shared group key in the key construction phase. For this phase, two different methods are tested. In the unicast approach, the key material is sent to each member individually using unicast messages, and in the multicast approach, a combination of Lagrange interpolation and a multicast packet are used. Finally, in the multicast communication phase, these keys are used to send confidential and authenticated messages. To investigate the impact of the proposed mechanisms on the WSN, the protocol was implemented in ContikiOS and simulated using COOJA, considering different group sizes and multi-hop communication. These simulations show that the multicast approach compared to the unicast approach results in significant smaller delays, is a bit more energy efficient, and requires more or less the same amount of memory for the code.
