Abstract
En 中文
The very-high-frequency data exchange system (VDES) is an emerging maritime radio communication system that will pave the road for novel e-navigation applications. A key problem in e-navigation is that of data authentication: deter- mining that the data originate from a trusted party and have not undergone changes after transmission. This work considers the authentication require- ments in VDES, while considering the constraints typical of the maritime environment, and analyzes several possible solutions. The proposed solution is two-tiered, with the default approach relying on digital signatures in low-traffic areas where available wireless capacity is sufficient. For areas under the con- trol of a shore station for which available wireless capacity is low, we con- sider a low-overhead authentication scheme using the timed efficient stream loss-tolerant authentication (TESLA) protocol to authenticate all shore-to-ship traffic. TESLA is particularly attractive for future-proof quantum-safe cryp- tography, offering increased authentication data under the conditions of the low-data-rate VDES.
