The Trusted Platform Module (TPM) is a hardware chip designed to enable computers to achieve a greater level of security. In the distributed environment all the systems are connected together with a limited bandwidth security feature. The TPM module will increase the security feature by the concept of DAA. Direct Anonymous Attestation (DAA) is a special digital signature primitive, which provides a balance between signer authentication and privacy. A DAA scheme involves a set of issuers, signers, and verifiers. An issuer is in charge of verifying the legitimation of signers and of issuing a DAA credential to each signer.
