This thesis introduces VMCStore, a framework for developing trusted storage applications on an untrusted server using a trusted platform module (TPM). The framework allows the server to provide trusted storage to a large number of clients, where each client may own and use several devices that may be offline at different times, and may not be able to communicate with each other, except through the untrusted server (over an untrusted network). The clients only trust the server's TPM; the server's BIOS, CPU, and OS are not assumed to be trusted. VMCStore draws on the ideas of virtual monotonic counters and validity proofs to provide tamper-evident storage, allowing the user to detect modifications to his data, as well as replay attacks. In particular, VMCStore uses TPM/J, a Java-based API for low-level access to the TPM, to create virtual monotonic counters using the monotonic counters and transport sessions of the TPM 1.2. VMCStore also provides a set of three log-based validation algorithms, which have been tested over PlanetLab and analyzed in this thesis. The VMCStore framework has been developed in a modular fashion, allowing the user to develop and test new applications and validation algorithms.
