ADATA: Asymmetric Device Identifier Composition Engine Compliant Aggregate Trust Attestation
Yang Liu, Huacheng Xiao, Jianqiang Li, Fajiang Yu, Yanting Huang · IEEE Access · 2025
The collective remote attestation scheme is an effective approach to securing interconnected IoT devices. However, existing solutions often have limited compatibility with deployed systems and impose high Trusted Computing Base (TCB) requirements. This paper introduces an asymmetric aggregated trusted attestation scheme based on the Device Identifier Composition Engine (DICE). By deriving attestation keys from device configurations, the proposed approach reduces TCB complexity and enhances suitability for existing deployments. Additionally, the scheme leverages aggregate signatures using general elliptic curves and distributed aggregation, effectively minimizing network communication overhead and attestation report size while improving aggregation efficiency. Furthermore, it incorporates non-adaptive group testing using a disjunct matrix to efficiently detect compromised devices.
