Remote attestation is the key technology of trusted cloud
computing. The existed remote attestation schemes are not sufficient to consider
the trusted measurement of the running virtual computing node. In this study,
by the analysis and comparison of existing remote attestation schemes, we propose
a trusted measurement of the running virtual computing node and a threshold
remote attestation scheme based on the trusted measurement results. By RO security
analysis and a simulation, we verify the security and efficiency of the scheme.
The trusted measurement of the running platform is mainly based on the trusted
measurement of the programs running on the platform and a total trust value
of the platform by an algorithm. The Threshold remote attestation for trusted
measurement of the running platform is based on K-CCA problem.
Remote attestation and CP-ABE (ciphertext policy-attribute
based encryption) algorithm are Independent of each other. In this study, by
the analysis and comparison of existing remote attestation technology and CP-ABE
algorithm, we propose a remote attestation scheme based on the CP-ABE algorithm.
Remote attestation scheme based on the CP-ABE algorithm includes both remote
attestation with a virtual computing node and remote attestation with a group
of virtual computing nodes. By a analysis, we verify the security and efficiency
of the program.
