摘要： A plurality of access units may be established with varying levels of privilege and access rights, such that the user may perform tasks carrying with them a high risk of viral infection in an access unit with a low level of privilege and access rights. When an authenticated user desires to perform tasks requiring a higher level of privilege and access rights, the user may switch to an access unit having a higher privilege and access rights level by instigating a physical action. The physical action may include selecting a button (included in either a UI or on a peripheral device), or inputting biometric data to switch among running access units. A signal instigated by the physical action is transmitted along a trusted path between the isolation kernel and where the physical action was instigated.

摘要： Plural guest operating systems run on a computer, where a security kernel enforces a policy of isolation among the guest operating systems. An exclusion vector defines a set of pages that cannot be accessed by direct memory access (DMA) devices. The security kernel enforces an isolation policy by causing certain pages to be excluded from direct access. Thus, device drivers in guest operating systems are permitted to control DMA devices directly without virtualization of those devices, while each guest is prevented from using DMA devices to access pages that the guest is not permitted to access under the policy.
摘要翻译：多个客户机操作系统在计算机上运行，其中安全内核在客户机操作系统之间执行隔离策略。排除向量定义了一组不能被直接存储器访问（DMA）设备访问的页面。安全内核通过使某些页面被排除在直接访问之外来执行隔离策略。因此，允许来宾操作系统中的设备驱动程序直接控制DMA设备，而不会对这些设备进行虚拟化，同时阻止每个客户端使用DMA设备来访问访客不允许访问策略下的页面。

摘要： A network-based data protection scheme for a mobile device utilizes encryption techniques and a remote key server that stores encryption keys on behalf of the mobile device. The mobile device stores encrypted data, preferably having no unencrypted counterpart stored therewith. On an as-needed basis, the mobile device requests a decryption key (or an encrypted version of a decryption key) from the key server, where the decryption key can be used by the mobile device to decrypt the encrypted information. The key server transmits the decryption key to the mobile device after authenticating the user of the mobile device.

摘要： Techniques for authenticating certificates of authenticity (COAs) are discussed. The techniques provide for a simplified authentication system that is easily utilized in a field setting. In described embodiments, COAs are attached to or otherwise associated with goods to be authenticated. The COAs incorporate random or pseudo-random arrangements of optically sensitive fibers to create unique identifiers. A COA reader device optically scans each COA and characterizes the COA according to its unique arrangement of optical activity. A COA reader device may also scan data (e.g., a barcode) that is associated with the COA. The data contains information about the COA to further strengthen the COA authentication process. Based on the scan, the goods associated with the COAs can be verified as genuine (i.e., not pirated).

摘要： A tamper response mechanism introduces a delayed failure into a program in response to detected tampering with the program. The mechanism determines a manner of responding to the detected tampering. The manner of responding may include corrupting a global pointer or using other techniques. The mechanism also determines when to respond to the tampering and implements the response at the determined time.

摘要： A method, apparatus, and article of manufacture for providing secure and opaque type libraries to automatically provide secure variables within a programming module. A system for providing secure and opaque type libraries to automatically provide secure variables within a programming module. The system includes an OTL selection module, an OTL substitution module, an OTL type library database, a compiler module; and a linker module to create an executable processing module. The OTL selection module randomly selects or generates one of the possible variable obfuscation functions for each declared secure variable. The OTL substitution module substitutes the separate instance of the selected variable obfuscation function for every reference to the declared secure variable. The OTL type library database receives queries from the OTL selection module a database to identify of possible variable obfuscation functions applicable for the variable type corresponding to the declared secure variables.

摘要： Techniques are disclosed to enable utilization of randomly-occurring features of a label (whether embedded or naturally inherent) to provide counterfeit-resistant and/or tamper-resistant labels. More specifically, labels including randomly-occurring features are scanned to determine the labels' features. The information from the scan is utilized to provide identifying indicia which uniquely identifies each label and may be later verified against the label features that are present to determine whether the label is genuine. In a described implementation, the identifying indicia may be cryptographically signed.
