Secure Key Transfer Protocol Based on Secret Sharing for Group Communications

Abstract

SUMMARYGroup key establishment is an important mechanism to construct a common session key for group communications. Conventional group key establishment protocols use an on-line trusted key generation center (KGC) to transfer the group key for each participant in each session. However, this approach requires that a trusted server be set up, and it incurs communication overhead costs. In this article, we address some security problems and drawbacks associated with existing group key establishment protocols. Besides, we use the concept of secret sharing scheme to propose a secure key transfer protocol to exclude impersonators from accessing the group communication. Our protocol can resist potential attacks and also reduce the overhead of system implementation. In addition, comparisons of the security analysis and functionality of our proposed protocol with some recent protocols are included in this article. key words: key transfer protocol, group key, Diffie-Hellman key agreement, secret sharing

ECIES for Group Key Establishment in WSN for Secure Multicast Communication

“…ECC is a lightweight public key cryptographic (PKC) solution which is defined with standard curve parameters and suitable for securing constrained devices [10]. In fact the protocol 1 is an ECC variant of reference [11] with improvements (e.g., ensure the integrity and the authenticity of data, and remove the MITM attacks). Protocol 2 is a further optimized variant of the solution in [2], [11], and [12], and an influenced variant of Elliptic Curve Integrated Encryption Scheme (ECIES).…”

Protocol 2 is a further optimized variant of the solution in [2], [11], and [12], and an influenced variant of Elliptic Curve Integrated Encryption Scheme (ECIES). ECIES is a hybrid encryption scheme that uses the functions such as key agreement, key derivation, encryption, message authentication, and hash value computation.…”

Novel secret sharing scheme based on key transfer protocols in a wireless sensor network environment

“…In the second type of approach, an online server must be active and can distribute group keys to every member of the group. Secret sharing is used for different protocols of WSNs, including group key management, and data confidentiality is required (Harn and Lin, 2010;Lee et al, 2011;Di Pietro and Guarino, 2013). Authenticated group key transfer protocol (AGKTP) introduced in Harn and Lin (2010) requires an online key generation center for constructing and distributing a group-based key.…”

“…These keys raise the overhead to construct the system while decreasing the system's flexibility. A method for replicating the keying scheme is explored in Lee et al, (2011), and this method is more active without a trusted server called KGC. In this regard, a group key created is between the trusted members and all the group members for the final key derivate.…”

“…In this regard, a group key created is between the trusted members and all the group members for the final key derivate. However, both schemes (Harn and Lin, 2010;Lee et al, 2011) cover coupling-based computations, which cannot deliver the cipher group for universally attached to WSN devices. Similarly, these schemes have security weaknesses as verified in Yuan et al (2013); these weaknesses include doubt of chasing the random values for every member in group and doubt on man in the middle attacks.…”
