摘要： Secure instant messaging is described. In an embodiment, a messaging device encrypts a challenge identifier to generate an encrypted challenge message, and communicates the encrypted challenge message via a peer-to-peer communication link to a recipient messaging device. The recipient messaging device decrypts the encrypted challenge message and encrypts the challenge identifier as a return challenge identifier to generate an encrypted challenge return. The messaging device receives the encrypted challenge return from the recipient messaging device, decrypts the encrypted challenge return, and verifies that the return challenge identifier matches the challenge identifier to establish that communications are secure when communicated via the peer-to-peer communication link and, optionally, to establish control policies pertaining to a communication received at the recipient messaging device.

摘要： Content synchronization in a file sharing environment is described. A node in a circle share maintains a version vector that represents that node's knowledge of file synchronization events. Version vector data may be transmitted between nodes of the circle share via a presence service in the form of short notification messages. The version vector data is compared to identify one or more nodes to be synchronized. A resource-aware overlay representing the circle share is computed, and is used to initiate communication to determine which of the available nodes with which to synchronize will provide the most synchronization value to other nodes in the circle share.

摘要： Strategies are described for validating content transferred over a communication channel using a more effective approach than heretofore provided in the art. A content registration authority is provided which registers the content disseminated by one or more content providers to one or more client devices. A client device which receives content that has been registered can securely consume the content, based on an assumption that a content provider which furnishes the content is entrusted by the content registration authority to provide the content, and without prompting a user of the client device to expressly approve the content provider. In a first solution, the content registration authority registers the content by issuing a certification stamp; in a second solution, the content registration authority registers the content by storing registration information in a central repository. The content may contain instructions which perform operations in the context of an instant messenger application.

摘要： A method, medium, and computer-program product is provided for tracking memory-usage characteristics of an application. The invention includes a suite of tools to evaluate memory usage of uninstrumented binaries by tracking memory allocations, deallocations, and in-memory-presence attributes at the module level. Memory-manipulation function calls (not limited to allocations and deallocations) are hijacked to code segments that annotate and log then-current memory characteristics. Processing is reverted back to its from-hijacked position and allowed to continue. In-memory presence of allocated memory and labels for certain points at time are tracked as well. The tracked data is logged so that algorithms can be run to extract desired information, which can be presented in various reports.

摘要： Various embodiments can utilize a distributed solution for scheduling connections between peers in a file sharing environment. In accordance with at least some embodiments, individual nodes in a peer-to-peer system include scheduling software that enables the nodes to make scheduling decisions with regard to how, when and where connections are made with other peers. Scheduling decisions can be based on a number of different parameters. In at least some embodiments, a synchronization negotiation manager is embodied with logic that drives the negotiation and scheduling process. This logic is represented by an innovative state machine that is designed to implement the negotiation and synchronization process.

摘要： A method and system for aging and scavenging resource records in a DNS database is provided. DNS resource records that are stored in a DNS database are assigned the timestamps indicating the last time the records were updated. Clients (owners of the resource records) periodically refresh timestamps of the DNS resource records that they registered using standard dynamic DNS update protocol. The DNS server then periodically searches its database for the stale records and deletes them. DNS database zone parameters and DNS server parameters are configured to define when a timestamp for a resource record may be updated, when a resource record may be scavenged (deleted) and which server may perform scavenging of a zone. A non-refresh interval follows the timestamp, a refresh interval follows the non-refresh interval and a scavengable period follows the refresh interval. During the non-refresh interval, an authorized DNS server may neither refresh nor scavenge the associated resource record. During the refresh interval, an authorized DNS server may refresh, but not scavenge the associated resource record. During the scavengable period, the resource record may be scavenged, if the timestamp is not renewed in the meantime. The build up of stale resource records, or records that have outlived their utility, is thus prevented improving system performance and conserving system memory and resources.
摘要翻译：提供了一种在DNS数据库中老化和清理资源记录的方法和系统。存储在DNS数据库中的DNS资源记录被分配指示上次更新记录的时间戳。客户端（资源记录的所有者）定期刷新他们使用标准动态DNS更新协议注册的DNS资源记录的时间戳。然后，DNS服务器定期搜索其数据库中的陈旧记录并将其删除。 DNS数据库区域参数和DNS服务器参数被配置为定义何时可以更新资源记录的时间戳，当资源记录被清除（删除）时，哪个服务器可能执行区域清理。非刷新间隔遵循时间戳，刷新间隔跟随非刷新间隔，可刷新周期在刷新间隔后。在非刷新间隔期间，授权的DNS服务器既不会刷新也不清除相关的资源记录。在刷新间隔期间，授权的DNS服务器可以刷新但不清除相关联的资源记录。在可扫描期间，如果时间戳没有更新，资源记录可能被清除。陈旧的资源记录的建立或者超过其实用程度的记录被阻止改善系统性能并节省系统内存和资源。
