- Abstract
- We consider the problem of migrating keys from TPM 1.2 to the backwards
incompatible TPM 2.0. The major differences between
the two versions introduce several challenges for deployed systems when
support for TPM 2.0 is introduced. We show how TPM 2.0 support can be
introduced while still maintaining the functionality specified by TPM 1.2,
allowing a smoother transition to the newer version. Specifically, we
propose a solution such that keys can be migrated from TPM 1.2 to TPM 2.0,
while retaining behavior with regard to e.g. authorization, migration
secrets, PCR values and CMK functionality. This is achieved by utilizing
new functionality, such as policies, in TPM 2.0. The proposed solution... (More) - We consider the problem of migrating keys from TPM 1.2 to the backwards
