A postgraduate student in City's Institute for Cyber Security (ICS) is attempting to plug the vulnerability gaps of smart cars to hacking and security breaches. Subhajit Bandopadhyay, studying for a Ph.D. under the supervision of Professor Muttukrishnan Rajarajan, director of the ICS, has been involved in collaborative research to develop the SIUV—a stateful smart car identity and access management (IAM) system, based on usage control (UCON) and verifiable credentials (VCs). SIUV comes out of Subhajit's research paper, co-authored by Professor Rajarajan, Ali Hariri (Huawei Munich Research Center and the University of Trento), Dr. Athanasios Rizos (Huawei Munich Research Center), Dr. Theo Dimitrakos (Huawei Munich Research Center and the University of Kent) and Professor Bruno Crispo (University of Trento), which was successfully submitted to the 36th International Conference on ICT Systems Security and Privacy Protection (IFIP SEC 2021) in June 2021. Over recent decades, several successive innovations have transformed the motor vehicle into a digital system on wheels. Otherwise known as intelligent cars, smart cars have evolved into safety-critical and cyber-physical systems which are increasingly exposed to cyber vulnerabilities. SIUV uses usage control policies in order to issue privileges to drivers or applications (such as the deployment of air bags or speed limit control) according to their credentials or claims. The issued privileges are then used to decide whether to grant or deny access to in-car resources. SIUV also continuously monitors subject claims, resource attributes and environmental conditions such as time or location so that if a change is made, the system can re-evaluate policies, provide updates or revoke issued privileges and usage decisions accordingly. To understand the work of Subhajit and his colleagues here is a realistic scenario. Alice, for example, goes to a car rental company to rent a vehicle for 48 hours to be driven in the London metropolitan area. The car rental company then defines the policies according to their agreement with Alice, and makes this information available for use via siuv Alice visits Cambridge briefly and thought the car rental company wouldn't be aware of this. When Alice was about to leave London's city limits, the car displays geographical restriction warnings and suggests rerouting to stay within the London metropolitan area. This occurs because of the continuous usage control architecture of SIUV. Verifiable credentials help keep claims secure and verifiable at all times, making them a great alternative to physical cards that are currently issued as driving licenses. The UK Driver and Vehicle Licensing Agency (DVLA) can be a potential trusted issuer of driving licenses in the form of verifiable credentials that are cryptographically verifiable. The claims within the credential can be continuously validated and access to the in-car components can be allowed or denied based on the usage control policy evaluations by SIUV. The automotive market is growing rapidly in transforming mechanical car components into digital systems. From a software perspective, this makes research work on the SIUV vital in comprehensively taking care of the safety and security of the smart cars of the future.

Being the world's largest producer of OLED televisions, LG has never offered a PC monitor based on this technology under its own brand. Earlier this year the company announced its first take on OLED for the PC space, the 4K UltraFine 32EP950 monitor, and now you can buy it at stores such as B&H Photo. The device addresses the needs of creative professionals across both Windows and macOS and costs a whopping $4,000. Specification wise, the LG UltraFine 32EP950 looks rather ordinary: a 3840 x 2160 resolution, a 250 bits peak brightness, a 60 Hz refresh rate and an ultra-high contrast rate. While a 250 nits luminance and a refresh rate numbers may not impress a gamer, keep in mind that we are talking about an OLED display for work and it does not usually require a very high brightness. Still, being aimed at professionals, the 32EP950 has its advantages. Historically, LG has positioned its UltraFine range for Apple's Macs, which almost always meant an exclusive support for Apple's Display-P3 color range, which was not exactly good for Windows. Therefore, perhaps a more interesting part about the LG OLED monitor is the color gamuts that the display supports. The UltraFine 32EP950 monitor supports a 99% coverage of both AdobeRGB and DCI-P3 (CIE1976) color gamuts. Like all OLED-based monitors, the LG UltraFine 32EP950 is costly. It is priced at $4,000, which is incredibly expensive, even when compared to other OLED monitors and TVs. For example, we recently reviewed the Gigabyte Aorus FO48U, a 48-inch OLED gaming monitor that reaches up to 120 Hz and costs around $1,700, less than a third of the price for a larger size and refresh rate. However, Gigabyte's monitor is meant to compete with the best 4K gaming monitors, not professional monitors.

Some problems are best solved by lighting a bundle of dynamite with a Zippo. During its digital showcase Realms Deep, 3D Realms ("still putting toilets in games") announced that it will be publishing Cultic, a retro FPS in the vein of Blood developed by Jasozz Games. In Cultic you play a detective who rises from the grave to get revenge on a bunch of hooded cultists with hatchets, taking them on with "a full arsenal of mid-century firearms and explosives". Expect a Mauser, Sten gun, and a lot of TNT then. Cultic also features a kick and the option to just chuck chairs or other improvised weapons at those smug cultist's faces. While the graphics are retro, Cultic features some modern movement options like dashing and sliding so you can get around quickly, but I expect to spend a fair amount of time rubbing against the walls looking for secret doors as well. "I am beyond excited for everyone to finally play CULTIC," said Jason Smith, sole developer at Jasozz Games. "This has been a dream project of mine since I first started tinkering with game development, and having it go from experimenting with an art style to a 3D Realms game has been incredible."

done.

https://www.bbc.com/news The number of migrants detained at the US-Mexico border in July exceeded 200,000 for the first time in 21 years, government data shows. A total of 212,672 migrants were apprehended by US Customs and Border Protection (CBP), including an all-time high of 19,000 unaccompanied minors. It continues a trend of rising migrant numbers this year, despite the White House urging people to stay away. Experts say many migrants are fleeing violence and extreme poverty. The July figure represents the highest monthly total since April 2000 - the latest sign of the growing humanitarian crisis facing the Biden administration. Attempted migrant crossings have historically dipped during the hot summer months along the nearly 2,000-mile southern border. But July's numbers are a 13% increase from June, when over approximately 188,000 migrants were detained by US border control. In May, 180,000 migrants were stopped in attempted crossings. On Thursday, US Homeland Security Secretary Alejandro Mayorkas described the situation as "one of the toughest challenges" the country faces. "It is complicated, changing and involves vulnerable people at a time of a global pandemic," he said. It is also proving politically troublesome for President Joe Biden. An AP-NORC poll in May found that 54% of Americans disapprove of how the Democrat is handling immigration issues. What is Biden doing differently at US border? Joe Biden's 'big problem' at the US border In early August, the Biden administration announced that it would indefinitely extend a Trump-era pandemic policy that allows the US to swiftly expel undocumented migrants. Unaccompanied children and some families are exempt. More than 45% of July's total were processed for expulsion under this policy, known as Title 42. Many, however, re-attempt the crossing. CBP data shows that 27% of the migrants detained last month had at least one prior encounter with authorities in the past year. The remaining 154,288 were recorded as "unique individuals". Between 2014 and 2019, the re-encounter rate stood at 14%. US authorities have also begun controversial "expulsion flights" that fly Central American families to southern Mexico. Officials have said they hope that these families return to their home countries, rather than the US border. But activists have warned that many families are dropped off in areas that put them at risk. Earlier this week, the United Nations High Commissioner for Refugees called the practice "a troubling new dimension" in Title 42 enforcement. Mr Mayorkas said that the migrants are being taken to "where it's far more difficult to try again." "We are working with Mexico to ensure for individuals subject to the expulsion flights [that] their needs are addressed." Tens of thousands of people from the Central American nations of Guatemala, El Salvador and Honduras have tried to enter the US in recent years. The reasons migrants give for why they undertake the dangerous journey are varied: family, better economic opportunity, or the chance to escape violence and corruption.

Kim Raisner was caught on camera slugging the horse and urging rider Annika Schleu to “really hit” her mount after it balked at jumping during a pivotal moment in Friday’s competition TOKYO — The coach of Germany's modern pentathlon team was kicked out the Tokyo Olympics on Saturday for, of all things, punching a horse. Kim Raisner was caught on camera slugging the horse and urging rider Annika Schleu to “really hit” her mount after it balked at jumping during a pivotal moment in Friday’s competition. At that point Schleu was in the lead — she went from first to 31st and left the arena in tears because the horse, whose name is “Saint Boy,” would not budge. Download the NBC News app for breaking news and politics Still, that was no excuse for her coach's behavior, the Modern Pentathlon Foundation (UIPM) said in a statement early Saturday. “The UIPM Executive Board (EB) has given a black card to the Germany team coach Kim Raisner, disqualifying her from the remainder of the Tokyo 2020 Olympic Games,” it said. “Her actions were deemed to be in violation of the UIPM Competition Rules, which are applied to all recognized Modern Pentathlon competitions including the Olympic Games.” Raisner was not part of the team's efforts on Saturday. Germany's Olympic team chief, Alfons Hoermann, said earlier the coach had been pulled out of the men's individual competition. He also demanded urgent rule changes from the international federation. Rules must change in such a way so that rider and horse are protected," Hoermann said. "The focus must be on the welfare of the animals and the fair competition for athletes." "We also consider that an urgent review of the incident is necessary, especially in terms of animal protection, and that the national and international federations draw their conclusions." The modern pentathlon is a venerable Olympic sport that dates back to 1912 and sees athletes compete in five different events — fencing, freestyle swimming, equestrian show-jumping, pistol shooting and cross-country running. The athletes don’t get to choose their horse and they’re given just 20 minutes to warm up their mount and bond with the animal. Evidently Schleu and “Saint Boy” failed to click. Schleu had a commanding lead going into the show jumping but with each refusal the German's frustration grew. She finally exploded with a scream that echoed through the empty stadium as tears poured down her face. Her coach urged her to hit the horse, with Raisner's orders to "really hit it, hit," heard live back in Germany, triggering a wave of criticism. Raisner herself punched the horse once above the back leg. Top ranked Michelle Gulyas and Ireland's Natalya Coyle suffered similar fates with their horses as they saw their own medal hopes crushed, dropping out of the top 10 and out of contention. Great Britain's Kate French won the gold.
