20150341792 | NETWORK AUTHENTICATION SYSTEM WITH DYNAMIC KEY GENERATION - A network authentication system with dynamic key generation that facilitates the establishment of both endpoint identity, as well as a secure communication channel using a dynamically-generated key between two end devices (potentially on separate local area networks). An interactive or noninteractive authentication protocol is used to establish the identity of the target end device, and dynamic key generation is used to establish a shared symmetric session key for creating an encrypted communication channel between the end devices. | 11-26-2015 |
20150318994 | SYSTEM AND DEVICE BINDING METADATA WITH HARDWARE INTRINSIC PROPERTIES - A system, device, and method for binding metadata, such as information derived from the output of a biometric sensor, to hardware intrinsic properties by obtaining authentication-related metadata and combining it with information pertaining to a root of trust, such as a physical unclonable function. The metadata may be derived from a sensor such as a biometric sensor, the root of trust may be a physical unclonable function, the combination of the metadata and root of trust information may employ a hash function, and output from such a hash process may be used as an input to the root of trust. The combined information can be used in interactive or non-interactive authentication. | 11-05-2015 |
20150317481 | SYSTEM AND DEVICE FOR VERIFYING THE INTEGRITY OF A SYSTEM FROM ITS SUBCOMPONENTS - A system and device for verifying the integrity of a system from its components, the system comprising a plurality of components each having a physical state, the system and the device comprising a processor that is connected to each of the components, the processor configured to verify systemic integrity by performing verification on some or all specified components. The verification may be individual (1, 1) or threshold (n, 1), and may be interactive or non-interactive. | 11-05-2015 |
20150317480 | SYSTEM AND DEVICE FOR VERIFYING THE INTEGRITY OF A SYSTEM FROM ITS SUBCOMPONENTS - A system and device for verifying the integrity of a system from its subcomponents, the system comprising a plurality of subcomponents each having a physical state, the system and the device comprising a processor that is connected to each of the subcomponents, the processor configured to verify systemic integrity by performing verification on some or all specified subcomponents. The verification may be individual (1,1) or threshold (n,1), and may be interactive or non-interactive. | 11-05-2015 |
20150134966 | Authentication System - A device authentication system for use with an authenticatable device having a physically-unclonable function and constructed to, in response to input of challenge C, internally generate an output O characteristic to the PUF and the challenge C, and configured to: i) upon receiving challenge C, generate a corresponding commitment value that depends upon a private value r, and ii) upon receiving an authentication query that includes the challenge C and a nonce, return a zero knowledge proof authentication value that corresponds to the commitment value. The system comprises an enrollment server having a working verification set that includes challenge C and corresponding commitment value, wherein: a) the enrollment server is configured to generate an authentication token that corresponds to the authentication value and includes a blinded value depending upon the private value r and a random value decryptable by the authenticatable device; and/or b) the system is configured to pre-process and convey data to the authenticatable device as part of an extended Boyko-Peinado-Venkatesan generation. | 05-14-2015 |
20140282925 | Personal Authentication Device and System for Securing Transactions on a Mobile Device - A personal authentication device for use with a mobile device, comprising a secure processor, a crypto engine supporting certificate functions, a wireless communication module, a cryptographic engine, a memory, a hardware based identity, a policy engine, one or more security features; and an on-board main power battery. Also a system comprising the personal authentication device and a verification authority, and an associated method of authentication. | 09-18-2014 |
20140201821 | Resilient Device Authentication System - A resilient device authentication system comprising: one or more verification authorities (VAs) including a memory loaded with a complete verification set that includes hardware part-specific data, and configured to create a limited verification set (LVS) therefrom; one or more provisioning entities (PEs) each connectable to at least one of the VAs, including a memory loaded with a LVS, and configured to select a subset of data therefrom so as to create an application limited verification set (ALVS); and one or more device management systems connectable to at least one of the PEs, including a memory loaded with an ALVS, and configured to manage device security-related applications through the performance of security-related functions on devices associated with the hardware part-specific data. | 07-17-2014 |
20140123223 | Resilient Device Authentication System - A resilient device authentication system comprising: one or more verification authorities (VAs) including a memory loaded with a complete verification set that includes hardware part-specific data, and configured to create a limited verification set (LVS) therefrom; one or more provisioning entities (PEs) each connectable to at least one of the VAs, including a memory loaded with a LVS, and configured to select a subset of data therefrom so as to create an application limited verification set (ALVS); and one or more device management systems connectable to at least one of the PEs, including a memory loaded with an ALVS, and configured to manage device security-related applications through the performance of security-related functions on devices associated with the hardware part-specific data. | 05-01-2014 |
