论文摘要
国家或国际海事当局用于处理各种海洋活动的许可要求。这些许可构成了时间和空间限制的授权，但是没有技术安全服务可以检查授权广泛的海洋资产。我们已经注意到了安全的AIS解决方案，适用于或多或少不断连接互联网的资产，例如具有卫星连接的船舶。水下自主资产构成的其他约束，即功能和连接性较小，可以通过使用对称的加密术来减轻。我们提出了一项安全服务，该服务允许根据大型对称密钥对资产授权状态进行自动检查。根据许可的时间和空间限制，即时间戳和地理编码的时间限制，可以在中央当局进行关键一代。我们的解决方案利用了RC5密码的特大密钥大小以及在开放位置代码系统中的Geocell的标准化编码。尽管我们开发并描述了用于离岸水下使用的解决方案，但如果类似地受到限制或依靠抗量子耐药性和计算经济对称方法的限制或想要依靠的带宽，那么空中和地面环境也可以利用它。
National or international maritime authorities are used to handle requests for licenses for all kinds of marine activities. These licenses constitute authorizations limited in time and space, but there is no technical security service to check for the authorization of a wide range of marine assets. We have noted secure AIS solutions suitable for more or less constantly internet-connected assets such as ships with satellite connections. The additional constraints posed by underwater autonomous assets, namely less power and connectivity, can be mitigated by using symmetric cryptography. We propose a security service that allows the automatized check of asset authorization status based on large symmetric keys. Key generation can take place at a central authority according to the time and space limitations of a license, i.e. timestamped and geocoded. Our solution harnesses the exceptionally large key size of the RC5 cipher and the standardized encoding of geocells in the Open Location Code system. While we developed and described our solution for offshore underwater use, aerial and terrestrial environments could also make use of it if they are similarly bandwidth constrained or want to rely on quantum-resistant and computationally economic symmetric methods.
