Summary of Conference Call on Quantum Computing and Cryptography Industry Overview - The conference discusses the rapid development of quantum computing, with significant advancements from companies like Google, Microsoft, and IBM in chip development. Chinese institutions are also conducting related research, with commercial quantum computers expected to emerge within the next 5-10 years, posing a major threat to existing cryptographic systems [2][11]. Key Points and Arguments - **Threat to Current Cryptographic Systems**: Quantum computing poses threats to three main types of cryptographic systems: asymmetric encryption (e.g., RSA, ECC), symmetric encryption, and hash algorithms. Asymmetric encryption is the most vulnerable, while symmetric encryption's security strength is halved, and hash algorithms may see their security strength drop to 60-70% or even one-third [4][12]. - **Long Promotion Cycle for Quantum-resistant Algorithms**: The promotion cycle for quantum-resistant algorithms is lengthy due to significant differences from existing cryptographic mechanisms, affecting performance, key lengths, and message processing lengths. This necessitates the re-establishment of industry standards in sectors like finance and electricity [6]. - **NIST's Quantum-resistant Algorithm Standards**: The National Institute of Standards and Technology (NIST) has released multiple quantum-resistant algorithms, with plans for additional releases. This indicates ongoing research and the need for multiple algorithms to address potential risks [7][18]. - **Progress of Domestic and International Manufacturers**: Internationally, companies like Thales and Utimaco have launched hardware security modules (HSM) supporting quantum-resistant algorithms. Domestically, Sanwei Xinan has released a full range of quantum-resistant products, including chips and software development kits [8][10]. - **China's Push for Independent Cryptographic Systems**: China's initiative to develop its own cryptographic systems stems from security concerns over backdoors in widely used algorithms exposed by the Snowden incident. The goal is to complete 50% of system upgrades by the end of 2027, although full replacement of foreign technology will take longer [9]. - **Impact of Quantum Computing on Web 3.0**: The security of Web 3.0 relies on blockchain technology, which is vulnerable to quantum computing, particularly in public key algorithms that ensure identity and asset security. This vulnerability could lead to identity theft and asset loss [13]. - **Mitigating Quantum Threats to Blockchain**: Addressing quantum threats requires new quantum-resistant algorithms rather than merely increasing algorithm strength. Current quantum computing faces challenges in materials and error correction, which must be overcome for existing algorithms to remain effective [14][15]. Additional Important Insights - **Hardware Updates Required for Quantum Algorithms**: Transitioning to quantum-resistant algorithms necessitates hardware updates, as current systems cannot be simply upgraded through software. Pilot projects are underway to assess impacts and develop new standards [16]. - **Future Hardware Updates for New Standards**: Even after initial hardware updates, further updates may be required if new post-quantum standards emerge, as current algorithms may not guarantee long-term security [17]. - **Agility and Reconfigurability in Cryptographic Systems**: Future cryptographic systems should be designed for agility, allowing quick transitions between algorithms. This includes modular designs that enable component upgrades without complete hardware replacement [19][20]. This summary encapsulates the critical discussions and insights from the conference call, highlighting the evolving landscape of quantum computing and its implications for cryptography and security.
