Privacy Preserving Self-Certified Signcryption Scheme in Trusted Modules
Zhu Sheng-lin · Beijing Youdian Xueyuan xuebao · 2009
Message trustworthy and behavior trustworthy are crucial between trusted computing modules.To overcome the key escrow problem and the secure channel issue between trusted computing modules that seem to be inherent to identity(ID)-based signcryption,an efficient ID-based self-certified signcryption scheme(IDSSS) is proposed,which can resist dishonest credential authority's(CA's) forging and colluding attacks in trusted computing module(TPM) channel.Security models,including confidentiality,unforgeability,ciphertext anonymity,and dishonest CA tractability,are discussed.The proposed scheme can be used in secure and anonymous transfer requirements such as privacy preserving and identity hiding.
