Patent application number | Description | Published |
20100082973 | Direct anonymous attestation scheme with outsourcing capability - A Direct Anonymous Attestation (DAA) scheme using elliptic curve cryptography (ECC) and bilinear maps. A trusted platform module (TPM) may maintain privacy of a portion of a private membership key from an issuer while joining a group. Moreover, the TPM can outsource most of the computation involved in generating a signature to a host computer. | 04-01-2010 |
20100332574 | Digital random number generator - A hardware-based digital random number generator is provided. The digital random number generator is a randomly behaving random number generator based on a set of nondeterministic behaviors. The nondeterministic behaviors include temporal asynchrony between subunits, entropy source “extra” bits, entropy measurement, autonomous deterministic random bit generator reseeding and consumption from a shared resource. | 12-30-2010 |
20110161672 | Provisioning, upgrading, and/or changing of hardware - In some embodiments a secure permit request to change a hardware configuration is created. The secure permit request is sent to a remote location, and a permit sent from the remote location in response to the permit request is received. The hardware configuration is changed in response to the received permit. Other embodiments are described and claimed. | 06-30-2011 |

20130159726 | METHOD AND APPARATUS TO PROVIDE SECURE APPLICATION EXECUTION - A technique to enable secure application and data integrity within a computer system. In one embodiment, one or more secure enclaves are established in which an application and data may be stored and executed. | 06-20-2013 |
20130198853 | METHOD AND APPARATUS TO PROVIDE SECURE APPLICATION EXECUTION - A technique to enable secure application and data integrity within a computer system. In one embodiment, one or more secure enclaves are established in which an application and data may be stored and executed. | 08-01-2013 |
20140201540 | SECURE KEY STORAGE USING PHYSICALLY UNCLONABLE FUNCTIONS - Some implementations disclosed herein provide techniques and arrangements for provisioning keys to integrated circuits/processors. A processor may include physically unclonable functions component, which may generate a unique hardware key based at least on at least one physical characteristic of the processor. The hardware key may be employed in encrypting a key such as a secret key. The encrypted key may be stored in a memory of the processor. The encrypted key may be validated. The integrity of the key may be protected by communicatively isolating at least one component of the processor. | 07-17-2014 |
20140205090 | METHOD AND SYSTEM FOR SECURELY COMPUTING A BASE POINT IN DIRECT ANONYMOUS ATTESTATION - A method and system computes a basepoint for use in a signing operation of a direct anonymous attestation scheme. The method and system includes computing a basepoint at a host computing device and verifying the base point at a trusted platform module (TPM) device. | 07-24-2014 |
20140270177 | HARDENING INTER-DEVICE SECURE COMMUNICATION USING PHYSICALLY UNCLONABLE FUNCTIONS - Embodiments of an invention for hardened inter-device secure communication using physically unclonable functions are disclosed. In one embodiment, an apparatus includes a first storage location, a second storage location, a physically unclonable function (PUF) circuit, a PUF key generator, and an encryption unit. The first storage location is to store an embedded key. The second storage location is to store a fuse key. The PUF circuit is to provide a PUF value. The PUF key generator is to generate a PUF key based on the PUF value. The encryption unit is to receive from a key server a global key encrypted using the embedded key, decrypt the global key using the embedded key, encrypt the global key using the PUF key, and store the global key encrypted using the PUF key in the second storage location. | 09-18-2014 |
