However, computer design, evaluation, and optimization typically leave the user out-of-the-loop. Recent studies [1, 3, 5] indicate that there is significant optimization potential in considering the user when making system-level decisions. One of key challenges in user-aware research lies in understanding user satisfaction. While it is possible to explicitly ask the user for feedback, such interaction may be annoying. An effective implicit form of user feedback would be ideal. In this paper, we argue for incorporating such feedback into future architectures/systems and ask the question: Can we use human physiological traits to make informed user-aware (empathic) architectural and system-level decisions? As an example, imagine the following scenario for a laptop user. An eye tracker follows the user’s line of vision. The OS scheduler increases the priority of the window which the user is focused on. During game play, the eye tracker recognizes user arousal through pupil dilation and notifies the game engine. To improve power consumption, several heuristics throttle CPU/memory/disk performance to minimize system performance to a level believed to satisfy the user. However, when biometric sensors indicate the user is annoyed, performance is increased, and the heuristics are updated accordingly.","PeriodicalId":120246,"journal":{"name":"Proceedings of the 13th international conference on Architectural support for programming languages and operating systems","volume":"16 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125763736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, it is infeasible economically for government-based IC suppliers to produce technology that matches the performance of commercial suppliers. These high-performance ICs provide a tactical advantage making them an indispensable resource. Second, commercial suppliers are moving more design, manufacturing, and testing of ICs to a geographically diverse set of countries in an effort to cut costs, making it infeasible to secure these steps in the IC life cycle. Together, these trends lead to an “enormous and increasing” opportunity for attack. Motivated attackers will subvert the IC supply chain if doing so provides sufficient value. Since modifying an IC is an expensive attack, it is doubtful that “script kiddies” will turn their adolescent energies to malicious processors, but the same cannot be said for attackers with resources. If malicious processors are capable of running valuable attacks, governments, terrorist organizations, and so on will deploy them despite their cost. Historically, these types of organizations are experienced at covert operations, and have demonstrated considerable ingenuity in pursuing their goals. In contrast, there is little work on malicious processors. If an attacker were able to include a malicious IC within a computer system, it would give them a fundamentally higher level of control compared to softwarebased attacks. While the recent SubVirt project shows that attackers can gain control over operating systems by using virtual-machine monitors (VMMs) to control the layer beneath, ICs occupy yet a lower layer. A malicious IC would be below all software, including VMMs, so compromising ICs gives attackers complete control over the entire software stack. This high level of control pro-","PeriodicalId":120246,"journal":{"name":"Proceedings of the 13th international conference on Architectural support for programming languages and operating systems","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131840828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
