“…Moreover, the group controller has a heavy storage cost as it must store the key-chain (instead of a single key in the LKH scheme case) of each internal node. The CSET (Computation and Storage Efficient Tree) [6] scheme permits to improve the LKH efficiency by considering the available sensor nodes resources when constructing the logical tree. The TKH (Topological Key Hierarchy) [5] scheme allows to reduce the communication cost of the rekeying messages delivery by mapping the logical key tree to the physical topology.…”

“…Many improvements [4][5][6]14] were designed to the LKH scheme. The OKD (One-way Key Derivation) [4] scheme further reduces the number of rekeying messages by means of a local computation of the group key, using a one-way hash function.…”

“…Revoked nodes can also replay an old group key in order to rejoin the group. In addition, some schemes [3,5,6] do not consider rekeying messages authentication which makes them vulnerable to messages injection attacks.…”

“…As a matter of fact, in some applications several groups managed by resource-constrained sensor nodes might be needed. In addition, the proposed schemes such as [3][4][5][6] suppose that the network has a multicast routing support to deliver the rekeying messages in a multicast way. However, multicast routing introduces a heavy overhead and communication cost for maintaining the multicast table and the multicast routes.…”

“…However, this solution requires an O(n) communication cost complexity, where n is the number of group members. So, numerous schemes have been proposed for the sake of reducing the communication, computation and storage cost needed for the rekeying process [3][4][5][6][7].…”

a b s t r a c tSecure group communication is a paradigm that primarily designates one-to-many communication security. The proposed works relevant to secure group communication have predominantly considered the whole network as being a single group managed by a central powerful node capable of supporting heavy communication, computation and storage cost. However, a typical Wireless Sensor Network (WSN) may contain several groups, and each one is maintained by a sensor node (the group controller) with constrained resources. Moreover, the previously proposed schemes require a multicast routing support to deliver the rekeying messages. Nevertheless, multicast routing can incur heavy storage and communication overheads in the case of a wireless sensor network. Due to these two major limitations, we have reckoned it necessary to propose a new secure group communication with a lightweight rekeying process. Our proposal overcomes the two limitations mentioned above, and can be applied to a homogeneous WSN with resource-constrained nodes with no need for a multicast routing support. Actually, the analysis and simulation results have clearly demonstrated that our scheme outperforms the previous well-known solutions.

SummaryDifferent devices with different characteristics form a network to communicate among themselves in Internet of Things (IoT). Thus, IoT is of heterogeneous in nature. Also, Internet plays a major role in IoT. So, issues related to security in Internet become issues of IoT also. Hence, the group and hierarchical management scheme for solving security issues in Internet of Things is proposed in this paper. The devices in the network are formed into groups. One of the devices is selected as a leader of each group. The communication of the devices from each group takes place with the help of the leader of the corresponding group using encrypted key to enhance the security in the network. Blom's key predistribution technique is used to establish secure communication among any nodes of group. The hierarchy is maintained such that the security can be increased further, but the delay is increased as it takes time to encrypt at every level of hierarchy. Hence, the numbers of levels of hierarchy need to be optimized such that delay is balanced. Hence, this algorithm is more suitable for delay‐tolerant applications. The performance of the proposed Algorithm is evaluated and is proved to perform better when compared with the legacy systems like Decentralized Batch‐based Group Key Management Protocol for Mobile Internet of Things (DBGK).

Summary Cloud computing has been gaining widespread significance in recent times, especially with the advent of state‐of‐the‐art communication technologies and data‐handling systems. Large volumes of data are being handled in real time and their availability is made feasible to consumers in an efficient manner through cloud computing networks. However, security of such data being transferred through clouds characterized in a centralized configuration is of prime concern, which has been investigated in this research paper. Secured transmission of data through a secured key transmission using appropriate authentication mechanism has been the driving force behind the research carried out in this paper. In order to resolve the existing issues in clouds in terms of computational as well as storage complexities, a secure key transmission Rivest‐Shamir‐Adleman (SKT‐RSA) protocol is proposed based on the secure key transmission. Key distribution between the certified authority and the end user is proposed. The proposed protocol is a tree‐based cluster key distribution scheme.
