For secure communication between any two neighboring sensing devices on the Internet of Things (IoT) environment, it is essential to design a secure device access control and key agreement protocol, in which the two phases, namely, “node authentication” and “key agreement” are involved. While the node authentication allows two sensing devices to authenticate each other using their own pre-loaded secret credentials in memory, the key agreement phase permits to establish a secret key between them if the mutual authentication is successful. In this paper, we propose a new certificate-based “lightweight access control and key agreement protocol in the IoT environment, called LACKA-IoT,” that utilizes the elliptic curve cryptography (ECC) along with the “collision-resistant one-way cryptographic hash function.” Through a detailed security analysis using the formal security under the “Real-Or-Random (ROR …
