Abstract
Today, the rapid expansion of the Internet of Things and Cloud Computing is bringing up increasing issues in keeping systems secure and trustworthy. One of the tools to achieve a better degree of security is the Trusted Platform Module (TPM), which consists of a tamper-resistant device that allows verification of the system state through Remote Attestation. This leads to new issues regarding user privacy, thus giving rise to the need to create a privacy-preserving way of performing system state attestation. The Direct Anonymous Attestation (DAA) is a set of cryptographic schemes used to create anonymous digital signatures through the help of the TPM.
