    摘要： Technologies for execute only transactional memory include a computing device with a processor and a memory. The processor includes an instruction translation lookaside buffer (iTLB) and a data translation lookaside buffer (dTLB). In response to a page miss, the processor determines whether a page physical address is within an execute only transactional (XOT) range of the memory. If within the XOT range, the processor may populate the iTLB with the page physical address and prevent the dTLB from being populated with the page physical address. In response to an asynchronous change of control flow such as an interrupt, the processor determines whether a last iTLB translation is within the XOT range. If within the XOT range, the processor clears or otherwise secures the processor register state. The processor ensures that an XOT range starts execution at an authorized entry point. Other embodiments are described and claimed.

    摘要： 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.

    摘要： An embodiment may include circuitry to generate, at least in part, and/or receive, at least in part, a packet. The packet may include at least one field and an encrypted payload. The at least one field may include, at least in part, a first key and/or at least one value. The first key and at least one value, as included in the at least one field, may be encrypted by a second key. The encrypted payload may be capable of being decrypted, at least in part, based, at least in part, upon the first key and/or the at least one value to yield an unencrypted payload. The unencrypted payload may include at least a portion of application layer data that is to be communicated in a secure session.

    摘要： 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.
