摘要： Methods, systems, and computer-readable storage media for selecting columns for re-encryption in join operations. In some implementations, actions include determining a first column and a second column to be joined, receiving a first key corresponding to the first column and a second key corresponding to the second column, receiving a first rank associated with the first key and a second rank associated with the second key, selecting the second column for re-encryption based on the first rank and the second rank, and providing the first column, the second column, and the first key for performing a join operation, the second column being re-encrypted based on the first key.

摘要： Methods, systems, and computer-readable storage media for optimizing query processing in encrypted databases. In some implementations, actions include receiving a query that is to be used to query an encrypted database, generating a plurality of query plans based on the query, each query plan including a local query and one or more remote queries, the local query being executable at a client-side and the one or more remote queries being executable at a server-side, selecting an optimal query plan from the plurality of query plans, providing one or more remote queries of the optimal query plan to the server-side for execution, receiving one or more remote results, and processing a local query of the optimal query plan and the one or more remote results to provide a final query result.

摘要： A computer-implemented method avoids policy-based deadlocks in execution of a workflow. The method includes receiving information describing a workflow. The workflow includes tasks, roles, site of tasks and security constraints related to the tasks. A data structure, representative of relationships between the tasks and the security constraints is automatically generated. An automated, design-time evaluation is performed using the data structure to determine a minimal number of resources to be assigned to the roles in order to execute the tasks of the workflow, and to avoid deadlock in execution of the tasks of the workflow as a result of security constraints.

摘要： A process of telecommunication between a plurality of subscriber stations in accomplished under control of a switching center which stores call numbers of the respective subscriber stations. Each of the subscriber stations requests registration with an additional subscriber identification at the switching center. The switching center assigns the additional subscriber identification to the respective call number. In addition, the switching center transfers to each of the subscriber stations at least the subscriber identifications of all of the other subscriber stations so that one of the stations can be selected.

摘要： The invention relates to a method for operating a telecommunications system having a switching station (BS) and a plurality of internal subscriber stations (HA1, HA2, HA3, HA4) which are connected to it and with whose aid the switching station (BS) can simultaneously operate a limited number of channels of the same or a different type and is characterized in that the switching station (BS) reports to all the internal subscriber stations (HA1, HA2, HA3, HA4) by transmitting a respective busy signal that a channel of the appropriate type is not available, each internal subscriber station (HA1, HA2, HA3, HA4) is changed by the busy signal to a state in which it cannot initiate a connection being set up on the corresponding channel. It furthermore relates to a telecommunications system for carrying out the method, which is characterized in that the switching station (BS) contains a signal generator (SG) which produces a respective busy signal and sends it to all the internal subscriber stations (HA1, HA2, HA3, HA4) when a channel of corresponding type is not available, and each of the internal subscriber stations (HA1, HA2, HA3, HA4) contains a blocking device (B), which can be driven by the respective busy signal and, on reception of the respective busy signal, changes the internal subscriber station (HA1, HA2, HA3, HA4) to a state in which it cannot initiate a connection being set up on the corresponding channel.
摘要翻译：本发明涉及一种用于操作具有交换站（BS）和多个内部用户站（HA1，HA2，HA3，HA4）的电信系统的方法，所述多个内部用户站（HA1，HA2，HA3，HA4）连接到该交换站并且借助于交换站（BS）同时操作相同或不同类型的有限数量的信道，其特征在于，交换站（BS）通过发送相应的忙信号来向所有内部用户站（HA1，HA2，HA3，HA4）报告信道（HA1，HA2，HA3，HA4）由忙信号改变为无法启动在相应通道上建立连接的状态。此外，本发明还涉及一种用于执行该方法的电信系统，其特征在于，交换站（BS）包含产生相应忙信号的信号发生器（SG），并将其发送到所有内部用户站（HA1，HA2 ，HA3，HA4），并且每个内部用户站（HA1，HA2，HA3，HA4）都包含阻塞装置（B），其可由相应的忙信号驱动，在接收到相应的忙信号时，将内部用户台（HA1，HA2，HA3，HA4）改变为不能在相应信道上发起建立连接的状态。
