An Identity-based Aggregate Signature Scheme for Wireless Sensor Network Environmental Monitoring

Aggregation signature technology can save transmission bandwidth and computational cost while providing message authentication for multiple users. It is suitable for message aggregation and batch signature verification in wireless sensor network environment monitoring. Based on the characteristics of wireless sensor network environment monitoring, this paper designs an identity-based aggregate signature scheme, which can aggregate the signatures of multiple sensor nodes into one signature and send it to the base station. The base station only needs to verify this signature to authenticate the messages sent by multiple sensor nodes. Based on the discrete logarithm problem of elliptic curves, it is proved that it is anti-existence forgery under adaptive selection message attack in stochastic prediction model. The scheme provides secure authentication for messages at low computational cost and is nonrepudiation.
