    • Improved access control techniques for use in a service-oriented computing environment are disclosed. For example, one method for authenticating a client in a service-oriented environment, wherein the service-oriented environment includes a plurality of services, includes the following steps. At least one service of the plurality of services is invoked. State information is associated with the at least one service invoked. The state information is used to authenticate a client with at least one service. Further, a method for access control in a service-oriented environment, wherein the service-oriented environment includes a plurality of services, includes the following steps. A rule specification language is provided. At least one rule is specified using the rule specification language. A verification is performed to determine whether or not the client satisfies the at least one rule. The client is granted access to a service when the client satisfies the at least one rule.
    • 公开了一种用于面向服务的计算环境中的改进的访问控制技术。 例如,一种用于在面向服务的环境中验证客户端的方法,其中面向服务的环境包括多个服务,包括以下步骤。 调用多个服务中的至少一个服务。 状态信息与所调用的至少一个服务相关联。 状态信息用于对至少一个服务的客户端进行身份验证。 此外,一种面向服务的环境中的访问控制方法,其中面向服务的环境包括多个服务,包括以下步骤。 提供规则规范语言。 使用规则规范语言指定至少一个规则。 执行验证以确定客户端是否满足至少一个规则。 当客户端满足至少一个规则时,客户端被授予对服务的访问权限。

    • Techniques for efficiently clustering objects based on access patterns are provided. For example, in an illustrative aspect of the invention, a technique for clustering a plurality of objects based on access patterns comprises the following steps/operations. A first group of sets is created in which at least one set includes a plurality of objects read in close temporal proximity to each other. A second group of sets is created in which at least one set contains a plurality of objects written in close temporal locality to each other. A third group of sets is created in which at least one set s1 is constructed by identifying at least two objects o1 and o2 in a same set of the first group. At least one object is added to set s1 which is included in a set including object o1 of the second group. At least one object is added to set s1 which is included in a set including object o2 of said second group.
    • 提供了基于访问模式高效地聚类对象的技术。 例如,在本发明的说明性方面,基于访问模式来聚类多个对象的技术包括以下步骤/操作。 创建第一组集合,其中至少一个集合包括彼此紧密地临时读取的多个对象。 创建第二组集合,其中至少一个集合包含以彼此紧密的时间局部性写入的多个对象。 创建第三组集合,其中通过识别同一组第一组中的至少两个对象o 1和o 2来构造至少一个集合s 1。 至少一个对象被添加到包括在包括第二组的对象o 1的集合中的集合s 1中。 至少一个对象被添加到包括在包括所述第二组的对象o 2的集合中的集合s 1中。
