Google’s Advanced Technology and Projects (ATAP) group developed Vault with the intent of having at least 1 GB available on the ARM-based chip, to support features like an immutable logging system, but internally at Google the ATAP team members have 4 GB of “isolated sealed storage” in their own versions, ATAP’s Mudge Zatko explained in an ATAP talk today.
The chip runs a custom-built Real Time Operating System (RTOS), Zatko said. The chips can allow people to communicate without exposing cryptographically sensitive data, he said.
Regina Dugan, ATAP’s vice president of engineering, described Vault as “your digital mobile safe.”
