Information erase by a discrete secure erase hardware logic

A method comprising:

• storing, in a nonvolatile memory of a security chip, a collection of encryption keys for encrypting information to produce encrypted information;
• while a collection of device processors of an electronic device is non-operational:
• receiving, at the security chip, an erase indication indicating a request to erase the encrypted information;
• in response to the erase indication, erasing, by a discrete secure erase hardware logic in the security chip, the collection of encryption keys in the nonvolatile memory;
• activating an output indication provided from the security chip;
• and
• activating an erase indicator at the electronic device in response to the activating of the output indication.

An electronic device comprising:

• an auxiliary power supply;
• a collection of device processors;
• and
• a security chip separate from the collection of device processors and powered by the auxiliary power supply while the collection of device processors is non-operational, the security chip comprising a discrete secure erase hardware logic to:
• receive an erase indication activated by a user and indicating a request to erase encrypted information in a persistent memory, the encrypted information encrypted using a collection of encryption keys in a nonvolatile memory of the security chip,
• in response to the erase indication, erase the collection of encryption keys in the nonvolatile memory, and
• activate an output indication provided from the security chip to cause activation of an erase indicator at the electronic device.
