【正文】 ber of grand challenges for IT that they hope will drive forward research, similar to the way the human genome project drove life sciences research through the 1990s. Ambitious goals include harnessing the power of quantum physics, building systems that can39。t go wrong, and simulating living creatures in every detail. A grand challenge is a goal recognized one or two decades in advance, achievement of which represents a major milestone in the advance of knowledge or technology, according to a report describing seven grand challenges to inspire and direct IT research, released Tuesday by the British Computer Society (BCS). Some of the challenges identified by the academics are of mercial interest to the puter industry, most notably the development of dependable systems, and of systems that model or behave like living anisms. To achieve the goal of building dependable puter systems, the scientists suggest building a verifying piler, a tool that proves automatically that a program is correct before allowing it to run something first written about in the 1950s. Other themes include the following: Architecture of brain and mind: Once seen as a matter for philosophical debate, explaining the connection between the brain (as puting machinery) and the mind (as a virtual software machine) is increasingly being a scientific problem of interest in the development of information processing systems。 Memories for life: As we all accumulate personal digital memories such as and photos, it will bee necessary to manage the information gathered over a human lifetime. The challenge is to allow people to gain maximum benefit from these auxiliary memories, while maintaining their privacy。 In vivo in silico: Through the human genome project, IT has already brought life sciences forward by leaps and bounds, but the next step is to make possible the puter 遼寧科技大學畢業設計（論文） 第 31 頁 simulation of entire living anisms, allowing scientists to examine a plant, animal or colony of cells in virtual reality, from the cellular scale on upwards, and at different speeds from freezeframe to faster than life。 Science for global ubiquitous puting: Many of us already carry several puting devices (cell phone, laptop, anizer) that municate with one another and with others further afield, but such munications sometimes fail, as software interacts in unexpected ways. The goal of this challenge is to develop a scientific basis for the design and engineering of a global, ubiquitous puting infrastructure so that the results of interactions between devices are entirely predictable or, simply put, that they work as we want them to。 Scalable ubiquitous puting systems: Not only do we want our devices to interact predictably and reliably, we also want them to interact with every other conceivable device but the plexity of many systems grows much faster than the number of nodes in the system. Computing engineers need scalable design principles: developing and applying them is the goal of this challenge。 Journeys in nonclassical putation: Classically, putation is viewed mathematically in terms of algorithms, but there are other ways to look at it. These include rethinking the rigid classification schemes puters use and turning to others based on family resemblance or on metaphor。 taking advantage of the behavior of materials at the molecular or subatomic scale to perform calculations in different ways (nanotechnology, quantum puting)。 using statistical models to pute how sure we can be that the answer lies in a particular range, rather than trying to calculate its exact value。 and finally, seeking inspiration from biological systems to develop properties such as autoimmune or evolving hardware. The search for inspiration began in 2020, as an initiative of the . Computing Research Committee, prompted in part by an early project of the . Computing Research Association. An academic conference followed, in March 2020, culminating in the publication of the report, Grand Challenges in Computing Research. The seven challenges are presented in seven chapters of the report, each one 遼寧科技大學畢業設計（論文） 第 32 頁 describing the ultimate goal, the kinds of research needed to reach that goal over a 15year period, and the disciplines that would need to be involved. The suggestions quite detailed for the early years but vaguer and more conjectural as they look further ahead are intended to provoke discussion of the longterm aspirations for puting research. The Grand Challenges report can be found on the BCS Web site As longtime readers already know, I’m a big fan of Bruce Schneier, CTO and founder of BT Counterpane. Besides being a cryptographic and puter security authority, cryptographic algorithm creator, and author of many bestselling books on security, Bruce produces some of the most relevant conversations on puter security. I consider his books, his Cryptogram newsletter, and his blog mustreads for anyone in puter security. Bruce is a guy who pushes us to rethink our currently held paradigms. He lays bare unsubstantiated dogma. I don’t always agree with Bruce. But many of the potent ideas that I disagreed with when he espoused them a half decade ago, I find myself agreeing with years later, ideas like how twofactor authentication won’t stop malicious hackers from stealing gobs of money from the online banking industry, and how the biggest problem with security, in general, is us and our irrational ranking of threats. I distinctly remember Bruce telling me a decade ago how puter security, with all of its advances, was more than likely going to get worse in the future. This was in the face of increasingly accurate antivirus programs, improved patch management, and solid improvements in OS security across all platforms
