摘要： Systems and methods are provided for resource access control in computer systems. Our approach includes new techniques for composing and authenticating principals in an access control system. Our principals may comprise information that identifies the role of the user of a computer system, the mechanism by which the user was authenticated, and program execution history. Thus, when a principal makes a request, access control determinations can be made based on the principal's identity. Access control lists may provide patterns that are used to recognize principals, thereby ensuring a level of security without enumerating precise identifiers for all of the possible principles that may request a particular resource.

摘要： A system is provided for reading and writing sectors which may be realized as either a disk device to the local operating system, or as a virtual disk device to a virtual machine. A user's computing environment is stored in the network in the form of a disk image, which may be a virtual disk image, for example. The virtual disk is realized on host computers through host-resident virtual machine monitors such as MICROSOFT VIRTUAL PC®. Portable memory devices, such as flash devices, buffer virtual disk writes and cache reads, greatly reducing the performance degradation associated with remote disk access. The cache is mobile so that it can be travel with the user. The flash device remembers commonly used virtual disk content fingerprints so that the host machine's local disk can be used to satisfy many common disk reads when ubiquitous static content is involved. Standard, frequently used software images might be distributed in advance to host machines. Flash disk contents are trickled back into the networked parent disk image in order to provide an automatic backup facility, adding the benefit of ensuring that the flash drive doesn't overflow.

摘要： A system is disclosed for recovery from a compromise of a replica in a weakly-consistent distributed collection. The system employs a collection manager for revoking a compromised replica, and one or more archival replicas for storing time-stamped versions. Upon a compromise, versions tainted by the compromised replica may be expunged from the collection. Thereafter, versions determined to be unaffected by the compromise may be returned to the collection using the time-stamped versions stored in the one or more archival replicas.

摘要： A distributed computer system includes a multiplicity of concurrently active processes. Each object is owned by one process. Objects are accessible to processes other than the object's owner. Each process, when it receives a handle to an object owned by any other process, sends a first "dirty" message to the object's owner indicating that the object is in use. When a process permanently ceases use of an object handle, it sends a second "clean" message to the object's owner indicating that the object is no longer in use. Each object's owner receives the first and second messages concerning usage of that object, stores data for keeping track of which other processes have a handle to that object and sends acknowledgement messages in return. The receiver of an object handle does not use the handle until its first message is acknowledged. Periodically, the object's owner sends status request messages to other processes with outstanding handles to that object to determine if any of those processes have terminated and updates its stored object usage data accordingly. A garbage collection process collects objects for which the usage data indicates that no process has a handle. The first and second messages include sequence numbers, wherein the sequence numbers sent by any process change in value monotonically in accordance with when the message is sent. Object owners ignore any message whose sequence number indicates that it was sent earlier than another message for the same object that previously received from the same process.
摘要翻译：分布式计算机系统包括多个并发活动的过程。每个对象都由一个进程拥有。对象可以访问对象所有者以外的进程。每个进程在接收到任何其他进程拥有的对象的句柄时，向对象的所有者发送第一个“脏”消息，指示对象正在使用中。当进程永久停止使用对象句柄时，它会向对象的所有者发送第二个“干净”消息，指示对象不再使用。每个对象的所有者接收关于该对象的使用的第一和第二消息，存储用于跟踪哪些其他进程具有该对象的句柄的数据，并且发送确认消息作为回报。对象句柄的接收者在其第一个消息被确认之前不使用句柄。定期地，对象的所有者向具有未处理的该对象的处理的其他进程发送状态请求消息，以确定这些进程中是否已经终止并相应地更新其存储的对象使用数据。垃圾收集过程收集使用数据指示没有进程具有句柄的对象。第一和第二消息包括序列号，其中任何进程发送的序列号根据消息的发送时间单位变化。对象所有者忽略任何消息，其序列号表示它早于先前从同一进程接收的同一对象的另一个消息发送。

摘要： A pattern matching access control system determines whether a principal should be granted access to use a resource based on properties of applications comprised by the principal. The principal name may be created when an application is loaded, invokes other applications (or programs) and/or assumes a new role context. Access is provided based on whether, for each application, the publisher is authorized by system policy to grant privilege as requested by the application. When a resource which requires the privilege is requested by a principal, an access control list (ACL) for the resource is expanded with a list of applications that have been authorized through their publisher to assert the privilege. The expanded ACL is compared to the principal name to determine resource access.
摘要翻译：模式匹配访问控制系统基于主体的应用程序的属性确定是否应授予主体访问权限以使用资源。可以在应用程序加载时调用主体名称，调用其他应用程序（或程序）和/或假定新的角色上下文。访问是基于每个应用程序，发布者是否被系统策略授权以根据应用程序请求授予特权来提供访问。当一个委托人请求一个需要该权限的资源时，该资源的访问控制列表（ACL）会被扩展，并通过其发布者授权的应用程序列表来声明该权限。将扩展的ACL与主体名称进行比较以确定资源访问。
