Despite of a controversial practice, having the key components of a product undergo accelerated aging has been a very effective approach for planned obsolescence. All previous studies on planned obsolescence merely focused on the aging process itself; however, if a malfunctioned product due to aging is still under its warranty, the manufacturer suffers from financial losses in the form of customer refund and/or product repair. In this paper, we reveal an enhanced planned obsolescence attack that takes the warranty issue into consideration. More specifically, aging of an NoC-based many-core chip is set to be slow before the warranty expires, and its aging process gets accelerated afterwards. Such controlled aging is achieved by manipulating the routing algorithm that influences the lifetime distribution of the NoC nodes. The routing-induced aging process is also integrated with a profit model to evaluate the profit gained from chip aging. Experimental results show that, with the proposed planned obsolescence attack and the profit model, the manufacturer can increase its profit margin by 15.54%, 25.69%, and 53.36%, respectively, compared to devices under a scheme without any attack, a scheme that aggressively accelerates chip aging, and a scheme that employs a measure to mitigate chip aging. Overall speaking, the proposed attack can give the manufacturer a clear advantage over customer who can barely notice the existence of such business practices, and consequently, some advanced countermeasure schemes need to be developed to balance the interests of the two parties.

老化的片上网络增强了计划中的过时攻击

尽管存在有争议的实践,但使产品的关键组件加速老化已成为计划过时的非常有效的方法。以前所有有关计划的过时的研究都只关注老化过程本身。但是,如果由于老化而导致的故障产品仍在保修期内,则制造商将遭受客户退款和/或产品维修等形式的财务损失。在本文中,我们揭示了一种增强的计划中的过时攻击,其中考虑了保修问题。更具体地说,在保修到期之前,基于NoC的多核芯片的老化速度设置得很慢,其老化过程随后会加速。通过控制影响NoC节点生命周期分布的路由算法,可以实现这种受控老化。布线引起的老化过程也与利润模型集成在一起,以评估从芯片老化中获得的利润。实验结果表明,与拟议的淘汰计划和利润模型相比,制造商与没有任何攻击的计划下的设备相比,可以分别提高其利润率15.54%,25.69%和53.36%。加速芯片老化,以及采用某种措施来减轻芯片老化的方案。总体而言,所提议的攻击可以使制造商明显胜过几乎无法注意到这种商业惯例的客户的优势,因此,需要制定一些先进的对策方案来平衡双方的利益。实验结果表明,与拟议的淘汰计划和利润模型相比,制造商与没有任何攻击的计划下的设备相比,可以分别提高其利润率15.54%,25.69%和53.36%。加速芯片老化,以及采用某种措施来减轻芯片老化的方案。总体而言,所提议的攻击可以使制造商明显胜过几乎无法注意到这种商业惯例的客户的优势,因此,需要制定一些先进的对策方案来平衡双方的利益。实验结果表明,与拟议的淘汰计划和利润模型相比,制造商与没有任何攻击的计划下的设备相比,可以分别提高其利润率15.54%,25.69%和53.36%。加速芯片老化,以及采用某种措施来减轻芯片老化的方案。总体而言,所提议的攻击可以使制造商明显胜过几乎无法注意到这种商业惯例的客户的优势,因此,需要制定一些先进的对策方案来平衡双方的利益。与采用无攻击方案的设备相比,该方案可显着加速芯片老化,而采用可减轻芯片老化的措施的方案。总体而言,所提议的攻击可以使制造商明显胜过几乎无法注意到这种商业惯例的客户的优势,因此,需要制定一些先进的对策方案来平衡双方的利益。与采用无攻击方案的设备相比,该方案可显着加速芯片老化,而采用可减轻芯片老化的措施的方案。总体而言,所提议的攻击可以使制造商明显胜过几乎无法注意到这种商业惯例的客户的优势,因此,需要制定一些先进的对策方案来平衡双方的利益。
