  • Pressrelease HUAWEI Develop
    ! PRESSMEDDELANDE Huawei utvecklarkonferens - Huawei bygger ekosystem och lockar samarbetspartners Huawei arrangerade utvecklarkonferensen Huawei Developer Conference (HDC) vid deras Songshan Lake-säte i Dongguan. 600 teknikexperter från Huawei träffade nästan 6000 utvecklare och samarbetspartners från hela världen för att prata om teknik och globala ekosystem under temat ”Rethink Possibilities”. Konferensen syftar till att utforska framtidens AI-baserade ekosystem, som ska ge en fulländad upplevelse för varje användare. När Huawei fortfarande var ny på marknaden, sålde företaget tre miljoner mobiltelefoner. Åtta år senare har antalet ökat 68 gånger om. Under första kvartalet 2019 sålde Huawei 118 miljoner mobiltelefoner, vilket är 17,6 procent av den globala mobilmarknaden enligt IDC och därtill en ökning med 24 procent från föregående år. Men även surfplattor, datorer och bärbara enheter har bidragit till Huaweis snabba tillväxt. Idag finns företaget i över 170 länder och har 530 miljoner användare. Huaweis öppna plattform, Huawei HiAI, har mer än 2500 partners och över 140 miljoner IoT-enheter världen över stödjer HiLink- protokoll. Huawei presenterade under konferensen det microkernel-baserade operativsystemet HarmonyOS och visade operativsystemets fördelar. Operativsystemet markerar en ny era av Internet of Everything och ger utvecklare effektiva verktyg som stöttar enkel utveckling av programvara till flera enheter. - HarmonyOS kopplar samman allt och öppnar för en miljardmarknad. HarmonyOS är inte bara till för idag och i morgon, utan är en katalysator för all teknik i framtiden. Huawei är dedikerade till att förbättra sina tekniker, inklusive chip och OS, med mål att hjälpa kunder och utvecklare, säger Yu Chengdong, vd för Huaweis Consumer Business. HarmonyOS är ett operativsystem med öppen källkod och med hjälp av Huawei Mobile Services (HMS) för globala utvecklare går det snabbt att komma åt HMS-ekosystemet för resursdelning.

  • Security Considerations for Releasing Mobile Banking Apps on the Huawei Appgallery
    The Huawei Report Security Considerations For Releasing Mobile Banking Apps On The Huawei AppGallery Author: Petr Dvořák Contact: [email protected] Date: 02 November 2020 Version: 1.0 Executive Summary Huawei, a global provider of ICT infrastructure and smart devices, has been in a negative spotlight lately. Many national security agencies have flagged this company as a potential security risk [1], with some countries imposing sanctions to impede Huawei’s operations [2]. Banks are considered critical infrastructure in most states. As a result, they need to evaluate their approach to Huawei, especially in the context of smartphones and portable devices their customers use to access digital banking. At the same time, they cannot merely ignore Huawei because it is currently the biggest smartphone vendor with a global smartphone market share of approximately 20%. The national security agencies are relatively vague in their recommendations. This may be intentional since providing industry-specific advice is complicated. As a result, banks and financial companies are ofen missing specific guidelines for dealing with Huawei-related questions. They ofen need to seek help and practical consulting from external cybersecurity experts. The question they ask the most is the following: “ Should we release our mobile banking to the Huawei AppGallery, and if we do, should we also invest in integrating Huawei Mobile Services (HMS)? It is not easy to answer this question with confidence for various reasons. Besides considering the security of the Huawei ecosystem and potential privacy risks, one must also consider the cost impact of maintaining the mobile app on a third marketplace. On the other hand, it is also impossible to ignore the large user base with Huawei devices.
