在共享频谱环境中，安全是一个至关重要的问题。除了降低服务质量外，攻击还会影响相互竞争的服务提供商（SP）之间的市场互动。本文通过考虑两个进行古诺竞争的服务提供商在使用专有频谱和共享频谱（共享频谱以授权形式或开放接入形式存在）时的情况来研究这些互动。此外，我们假设存在一个攻击者，其目的是在部分时间内拒绝一个或多个共享频段的服务，从而减少总体总收入。我们分析了在不同攻击者目标下的最优攻击形式以及它们对所产生的市场均衡的影响。利用这些分析，我们比较了各种频谱共享方法（授权和开放接入）以及两个提供商不同的频谱持有量的影响。
Security is a critical concern in shared spectrum environments. In additional to degrading service, attacks can influence the market interactions between competing service providers (SPs). This paper investigates these interactions by considering two SPs engaged in Cournot competition while utilizing both proprietary and shared spectrum, with shared spectrum available in either licensed or open-access forms. Additionally, we assume the presence of an attacker whose objective is to deny service to one or more of the shared bands for a fraction of the time, consequently reducing the overall total revenue. We analyze the optimal forms of attacks under different attacker objectives and their repercussions on the resulting market equilibrium. Utilizing these analyses, we compare the impacts of various spectrum sharing approaches (licensed and open access) and differing amounts of spectrum holdings of the two providers.
