PUBLIC KEY PROTECTION TECHNIQUES

Abstract:

Methods, systems, and devices for public key protection techniques are described. An embedded multimedia card (eMMC) may be formatted to include a permanent write protect group that is configured to prevent disabling of write protection for data stored in the permanent write protect group. The eMMC may store a public key associated with a first host device in the permanent write protect group of the eMMC. A data package may be received from the host device and authenticated by using the public key stored in the permanent write protect group. The embedded memory controller may be configured to prevent modifying or writing data to a permanent write protect group.
