20120166812 | METHOD, APPARATUS AND SYSTEM FOR SECURE COMMUNICATION OF RADIO FRONT END TEST/CALIBRATION INSTRUCTIONS - Techniques for a programmable engine to provide security mechanisms protecting information which is in support of testing and/or calibration a radio front end. In an embodiment, test/calibration information is to be communicated to, from or within the programmable engine for processing by a particular resource of the programmable engine. In another embodiment, test/calibration is exchanged along a dedicated hardware data path between a security module of the programmable engine and an execution module of the programmable engine, wherein any data exchanged in the dedicated hardware data path is only accessible from the dedicated hardware data path via one or both of the security module and the execution module. | 06-28-2012 |
20130279690 | PRESERVING IMAGE PRIVACY WHEN MANIPULATED BY CLOUD SERVICES - An apparatus and method for preserving image privacy when manipulated by cloud services includes middleware for receiving an original image, splitting the original image into two sub-images, where the RGB pixel values of the sub-images have a bit value that is less than RGB pixel values of the original image. The sub-images are encrypted by adding a keystream to the RGB pixel values of the sub-images. The sub-image data is transmitted to a cloud service such as a social network or photo-sharing site, which manipulate the images by resizing, cropping, filtering, or the like. The sub-image data is received by the middleware and is successfully decrypted irrespective of the manipulations performed by the cloud services. In an alternative embodiment, the blocks of the original image are permutated when encrypted, and then reverse-permutated when decrypted. | 10-24-2013 |
20130311777 | SYMMETRIC KEY DISTRIBUTION FRAMEWORK FOR THE INTERNET - A method, device, and system are disclosed. In one embodiment the method includes receiving measured health information from a client on a key distribution server. Once the measured health information is received the server is capable of validating the measured health information to see if it is authentic. The server is also capable of sending a session key to the client when the measured health information is validated. When the client receives the session key, the client is capable of initiating an encrypted and authenticated connection with an application server in the domain using the session key. | 11-21-2013 |
20140032924 | MEDIA ENCRYPTION BASED ON BIOMETRIC DATA - Embodiments of techniques and systems for biometric-data-based media encryption are described. In embodiments, an encryption key may be created for a recipient user based at least in part on biometric data of the recipient user. This encryption key may be maintained on a key maintenance component and used by a sharing user to encrypt a media file for access by the recipient user. One or more access policies associated with recipient user may be encrypted in the encrypted media file as well. In embodiments, the media file may be encrypted for use by multiple recipient users. When a recipient user desires to access the encrypted media file, a decryption key may be generated in real time based on contemporaneously captured biometric data and used to provide access to the encrypted media file. Other embodiments may be described and claimed. | 01-30-2014 |
20140040632 | LOW-OVERHEAD CRYPTOGRAPHIC METHOD AND APPARATUS FOR PROVIDING MEMORY CONFIDENTIALITY, INTEGRITY AND REPLAY PROTECTION - A method and system to provide a low-overhead cryptographic scheme that affords memory confidentiality, integrity and replay-protection by removing the critical read-after-write dependency between the various levels of the cryptographic tree. In one embodiment of the invention, the cryptographic processing of a child node can be pipelined with that of the parent nodes. This parallelization provided by the invention results in an efficient utilization of the cryptographic pipeline, enabling significantly lower performance overheads. | 02-06-2014 |
20140044258 | METHODS AND SYSTEMS FOR CRYPTOGRAPHIC ACCESS CONTROL OF VIDEO - Methods and systems for cryptographic access control of multimedia video, include embedding as metadata access control policy (ACP) information, including authorization rules and cryptographic information tied to an encryption policy, into encrypted video. An authorized receiver device having credentials and/or capabilities matched to the authorization rules is able to extract the ACP information from the encrypted video and use it to decrypt and properly render the video. | 02-13-2014 |
20140101461 | PARALLELIZED COUNTER TREE WALK FOR LOW OVERHEAD MEMORY REPLAY PROTECTION - A processor includes a memory encryption engine that provides replay and confidentiality protections to a memory region. The memory encryption engine performs low-overhead parallelized tree walks along a counter tree structure. The memory encryption engine upon receiving an incoming read request for the protected memory region, performs a dependency check operation to identify dependency between the incoming read request and an in-process request and to remove the dependency when the in-process request is a read request that is not currently suspended. | 04-10-2014 |
20140137231 | INCORPORATING ACCESS CONTROL FUNCTIONALITY INTO A SYSTEM ON A CHIP (SoC) - In one embodiment, the present invention includes a system on a chip (SoC) that has a first agent with an intellectual property (IP) logic, an interface to a fabric including a target interface, a master interface and a sideband interface, and an access control plug-in unit to handle access control policy for the first agent with respect to incoming and outgoing transactions. This access control plug-in unit can be incorporated into the SoC at integration time and without any modification to the IP logic. Other embodiments are described and claimed. | 05-15-2014 |
20140208109 | METHOD AND SYSTEM FOR PROTECTING MEMORY INFORMATION IN A PLATFORM - A method and system to provide an effective, scalable and yet low-cost solution for Confidentiality, Integrity and Replay protection for sensitive information stored in a memory and prevent an attacker from observing and/or modifying the state of the system. In one embodiment of the invention, the system has strong hardware protection for its memory contents via XTS-tweak mode of encryption where the tweak is derived based on “Global and Local Counters”. This scheme offers to enable die-area efficient Replay protection for any sized memory by allowing multiple counter levels and facilitates using small counter-sizes to derive the “tweak” used in the XTS encryption without sacrificing cryptographic strength. | 07-24-2014 |
