Abstract
An apparatus to facilitate security within a computing system is disclosed. The apparatus includes a storage drive, a controller, comprising a trusted port having one or more key slots to program one or more cryptographic keys and an encryption engine to receive the cryptographic keys via the one or more key slots, encrypt data written to the storage drive using the cryptographic keys and decrypt data read from the storage drive using the cryptographic keys.
Claims20
An apparatus comprising:
- a non-volatile memory, including:
- a storage drive;
- a host controller, comprising a trusted port having one or more key slots to program one or more cryptographic keys;
- an encryption engine to receive the cryptographic keys via the one or more key slots, encrypt data written to the storage drive using the cryptographic keys and decrypt data read from the storage drive using the cryptographic keys;
- and
- a security controller to receive a key from a physically unclonable function (PUF) engine, generate the cryptographic keys using the received key and provide the cryptographic keys to the encryption engine via the one or more key slots.
3 more elements
A method comprising:
- receiving a key at a host controller from a physically unclonable function (PUF) engine;
- generate cryptographic keys using the received key;
- programming the cryptographic keys into a trusted port having one or more key slots in the host controller;
- and
- performing cryptographic operations via the cryptographic keys in the one or more key slots.
2 more elements
A computing device comprising:
- a processor;
- a memory device;
- a fabric interface coupled between the processor and the memory device;
- and
- a non-volatile memory, coupled to the fabric interface, including:
- a storage drive;
- a host controller comprising a trusted port having one or more key slots to program one or more cryptographic keys;
- and
- a encryption engine to receive the cryptographic keys via the one or more key slots, encrypt data written to the storage drive using the cryptographic keys and decrypt data read from the storage drive using the cryptographic keys;
- and
- a security controller to receive a key from a physically unclonable function (PUF) engine, generate the cryptographic keys using the received key and provide the cryptographic keys to the encryption engine via the one or more key slots.
