“…SeGCom and LEAP require synchronization between members since they use µT esla. According to [78], [79], this can be hard to achieve in highly distributed applications, such as WSNs. Most schemes do not provide the GMM component, but only describe the GKM component.…”

A key feature for Internet of Things (IoT) is to control what content is available to each user. To handle this access management, encryption schemes can be used. Due to the diverse usage of encryption schemes, there are various realizations of 1-to-1, 1-to-n, and n-to-n schemes in the literature. This multitude of encryption methods with a wide variety of properties presents developers with the challenge of selecting the optimal method for a particular use case, which is further complicated by the fact that there is no overview of existing encryption schemes. To fill this gap, we envision a cryptography encyclopedia providing such an overview of existing encryption schemes. In this survey paper, we take a first step towards such an encyclopedia by creating a sub-encyclopedia for secure group communication (SGC) schemes, which belong to the n-to-n category. We extensively surveyed the state-of-the-art and classified 47 different schemes. More precisely, we provide (i) a comprehensive overview of the relevant security features, (ii) a set of relevant performance metrics, (iii) a classification for secure group communication schemes, and (iv) workflow descriptions of the 47 schemes. Moreover, we perform a detailed performance and security evaluation of the 47 secure group communication schemes. Based on this evaluation, we create a guideline for the selection of secure group communication schemes.

“…Low capacity sensor nodes reqmre little buffering on the receiver side. Low-Buffer ,uTESLA protocol stated in [1] intends to swap receiver buffering with the sender buffering which is usually a more powerful base station. In this scheme, the Message Authentication Code or MAC that is used for encryption purposes and is a shorter version of the original message is sent instead of the longer message.…”

“…The main idea in Low-Buffer ,uTESLA protocol [1] seems undoubtedly attractive since it intends to reduce the memory requirements for receiving nodes by simply substituting the buffering of the content of a message and the corresponding MAC by storing only the MAC. In this scheme, the more resourceful sender buffers the message chunk instead of the receiver and sends only the MAC of the message.…”

“…Firstly the ,uTESLA scheme mentioned in [2] that has improved the original,uTESLA technique by facilitating immediate authentication through sending the hash of a future packet with the current packet is implemented in OPNET. Furthermore a second scenario is simulated in the same environment that incorporates the first scenario with the memory efficient ,uTESLA protocol mentioned in [1] by buffering the MAC of the message instead of the original massage in the resource constrained receiver node. The integration of these two methods is hoped to achieve immediate authentication while at the same time optimally reduce receiver buffering requirements.…”

Due to the nature of wireless sensor networks, security is a critical problem since resource constrained and usually unattended sensors are much vulnerable to malicious attackers that may impersonate the sender. Therefore authenticating received messages is a crucial matter to protect the system integrity. Generally used TESLA (Timed Efficient Stream Loss-tolerant Authentication) based authentication techniques involve consecutive delays for decryption purposes. These delays render the network vulnerable to different malicious attacks such as Denial of Service attack. As several techniques try to achieve immediate authentication to alleviate these threats, other factors such as reliability and buffer requirements may have been compromised. This project proposes an integration of Low Buffer ,uTESLA protocol and an immediate authentication protocol to achieve a new refined scheme in broadcast authentication in sensor networks. Performance analysis and simulation results demonstrate that the proposed method succeeds to achieve immediate authentication while preserving desired security and low memory requirements in sensor nodes.
