摘要： Encryption keys in a communication system are updated according to rekey groups having a common set of encryption keys or CKRs. Each group includes a number of radios with active and inactive keysets. A database records the relationships between rekey groups and keys, and the status of their keysets. An operator first determines one or more keys to be updated. New keys are then transmitted to each radio in one or more rekey groups using respective rekey messages. The new keys are stored in the inactive keysets of the radios. The inactive keysets are then activated using respective changeover messages. Deployment of new keys is carried out by software in the form of automated update tasks.

摘要： Embodiments of the invention assist conversion of an old data table to a new data table in a communication terminal. An edit script is created by creating an old and new data trees from the old and new tables respectively. A first partial script which converts the old tree to an intermediate tree having the same length as the new tree is then determined. A second partial script which converts the intermediate tree to the new tree is also determined. The first and second partial scripts are then combined to provide a script which can be sent the terminal. The first partial script is preferably a minimum cost series of edits causing only insertions and deletions in the old data tree. The second partial script is preferably a minimum cost series of edits causing only substitutions in the intermediate tree.
摘要翻译：本发明的实施例有助于将旧数据表转换成通信终端中的新数据表。通过分别从旧表和新表创建一个旧的和新的数据树来创建一个编辑脚本。然后确定将旧树转换为与新树具有相同长度的中间树的第一部分脚本。还确定了将中间树转换为新树的第二部分脚本。然后组合第一和第二部分脚本以提供可以发送终端的脚本。第一部分脚本优选是仅在旧数据树中仅插入和删除的最低成本编辑系列。第二部分脚本优选地是在中间树中仅导致替换的最小编码成本序列。
