An
Attribute Credential Based Public Key Scheme for Fog Computing in Digital
Manufacturing
Abstract:
In order to meet low
latency, service sensitive and location awareness requirements of digital
manufacturing, fog computing is introduced to be an intermediate layer between
industrial Internet of Things and cloud. The distributed, dynamic
characteristics and the collaboration requirement make it face many new
security and privacy issues that cannot be solved by the traditional public key
or symmetric cryptosystem. For addressing them, a registered but anonymous
attribute credential is designed to manage the network entities. Based on it,
an attribute credential based public key cryptography (AC-PKC) is constructed
to provide flexible key management by taking the advantage of the
certificate-less public key cryptography and the combination property of the
elliptic curve cryptography. Encryption, authentication, and access control
with privacy preserving can be realized on the basic operations of AC-PKC,
which can meet various security requirements of fog computing based digital
manufacturing. The performance analyses and comparison with the existing public
key schemes and attribute based encryption solutions show that the proposed
scheme can work flexibly at a relatively low cost.
