Abstract—The Industrial Internet of Things (IIoT), through
the extensive deployment of devices for sensing, transmitting,
and analyzing production states, can provide users with more
comprehensive services and enhance production and manufacturing efficiency. However, most IIoT devices are limited by
software and hardware resources, and existing mature security
mechanisms are no longer suitable due to high computing and
communication costs. This weakness makes these devices highly
susceptible to illegal attacks, such as counterfeiting, leading to
a decline in service quality of IIoT. Therefore, to ensure the
secure and efficient verification of the legitimacy of numerous
IIoT devices, scholars have employed numerous viable solutions.
However, many existing solutions have difficulty achieving a
balance between the limited resources and security requirements
of IIoT, resulting in certain shortcomings. To address this, we first
propose a lightweight certificateless signature scheme without
pairing, which can achieve unforgeability and reduce computation pressure by batch verification for multiple signatures.
Furthermore, we propose a lightweight certificateless mutual
authentication scheme (LCLMA-BS) for the IIoT. LCLMA-BS
is capable of conducting key agreement for both authentication parties and batch authentication for multiple participants.
Moreover, through analysis and proof, LCLMA-BS is shown
to have various security properties, such as perfect forward
and backward security and known session-specific temporary
information security. Finally, the simulation results indicate that
our signature and LCLMA-BS exhibit higher computational
efficiency and communication efficiency, demonstrating better
suitability for the IIoT
