Tactical edge networks are characterized by wireless links that have limited capacity and are prone to disconnection. In such a challenging and hostile environment, replication of information could be desirable as it increases information availability through redundancy and accessibility through proximity. However, replication of information has a negative effect on security because it broadens the attack surface -- more nodes may be targeted to obtain sensitive information, thereby potentially increasing the overall risk of the information being compromised or leaked. Furthermore, replicating information takes away resources (particularly communications and power, but also to some extent computation and storage) from other tasks that might also need the same resources. These trade-offs between information availability, information protection, and resource utilization exist and need to be explored in the context of different solutions that could be applied to the challenging problem of information dispersal for assured operations in tactical environments.

探索战术边缘网络中的性能权衡

战术边缘网络的特点是无线链路容量有限且容易断开连接。在这样一个充满挑战和敌对的环境中，信息的复制可能是可取的，因为它通过冗余和邻近性来增加信息的可用性。然而，信息的复制对安全有负面影响，因为它扩大了攻击面——更多的节点可能成为获取敏感信息的目标，从而潜在地增加了信息被破坏或泄露的整体风险。此外，复制信息会从可能也需要相同资源的其他任务中夺走资源（特别是通信和电力，但在某种程度上也需要计算和存储）。这些信息可用性、信息保护、
