Hierarchical-CPK-Based Trusted Computing Cryptography Scheme
PKI-based trusted computing platform (TCP) requires platform users to apply for multiple Platform Identity Key (PIK) certificates to provide remote attestation, users must pay the fee of digital certificates, which increases users’ economic burdens and leads there is hardly any TCP has really performed the core function of trusted computing, platform remote attestation, so the application of TCP is not very wide. This paper presents a trusted computing cryptography scheme based on Hierarchical Combined Public Key (HCPK), which can reduce the risk of single Private Key Generator (PKG), and let the verifier authenticate TCP directly without third party, so platform users do not need to apply additional digital certificates. This scheme can reduce users’ cost of using TCP, and encourage the development of TCP application.
