信息安全作为战略有效性

Information Security as Strategic (In)effectivity

Wojciech Jamroga, Masoud Tabatabaei

摘要:

信息流动的安全通常被理解为防止任何信息泄露,无论泄露可能造成多么严重或无害的后果。在这项工作中,我们认为,信息安全本身不是一个目标,而是一种手段,防止潜在的攻击者损害系统的正确行为。为了正式说明这一点,我们首先展示了两个信息流可以通过查看对手的能力来比较,以损害系统。然后,我们提出,在一个系统中的信息流是有效的信息安全,如果它不允许更多的伤害比其理想化的变体的基础上的经典概念的不干扰。

英文摘要:

Security of information flow is commonly understood as preventing any information leakage, regardless of how grave or harmless consequences the leakage can have. In this work, we suggest that information security is not a goal in itself, but rather a means of preventing potential attackers from compromising the correct behavior of the system. To formalize this, we first show how two information flows can be compared by looking at the adversary's ability to harm the system. Then, we propose that the information flow in a system is effectively information-secure if it does not allow for more harm than its idealized variant based on the classical notion of noninterference.
