Thales said that Microsoft is using its nShield hardware security modules.
Rights management, said Thales, was largely handled by infrastructure within enterprises. But shifting to a cloud model allows more accessibility and ease of use.
Microsoft thinks that by using an nShield MSM to allow the transfer of individual critical keys more security will be available to companies.
Microsoft partner management Dan Plastina said that because it was working with Thales its customers can generate and upload master keys to a cloud based HSM.
