Elliptic Curve Cryptosystems-based Date-constrained Hierarchical Key Management Scheme in Internet of Things

Abstract

In this paper, we propose a new mechanism to improve the disadvantage of the security mechanism proposed by a scholar and then fulfill the demands of Internet of Things (IoT) to go through the decentralized environment access control functions. We also propose the date-constrained hierarchical key management scheme for mobile agents. With elliptic curve cryptosystems (ECCs) and discrete logarithms, the proposed scheme is flexible. Moreover, the duration of access for each security class is restricted with a certain authorized discrete time period. We demonstrate the mathematical derivation and arguments for our scheme and further conduct a numerical trial. The constructed scheme could meet security needs and be more space-efficient.

An Efficient Key Management Technique for the Internet of Things

“…Recently, researchers in [10,[19][20][21] proposed a stable shared encryption protocol focused on ECDH and ECC for secure communication of embedded devices. This scheme provides mutual authentication and essential requirements for security.…”

“…There are notable works in order to provide authentication and protection of IoT data transfer with a focus on key management. Examples include mutual key management technique (KMP) [8], group key management technique (GKMP) [9], Elliptic Curve Cryptography (ECC)/Elliptic Curve Diffie Hellman (ECDH) based key management [10] etc. Some of these techniques utilize asymmetric cryptosystems while others utilize symmetric key cryptosystems.…”

Cluster space key management scheme based on threshold secret sharing and bilinear pairing

“…Furthermore, it does not consider the dynamic changes of the nodes. In 2019, a decentralized key management scheme for the Internet of things is proposed in Hsiao and Chen 26 . However, it needs PKI and takes several rounds of interaction.…”
