Google Accelerates Post-Quantum Cryptography Migration to 2029 Amid Quantum Threats

• •Google aims to migrate to post-quantum cryptography by 2029, ahead of NIST's 2030 deadline.
• •Store-now-decrypt-later attacks pose an immediate risk to current encryption methods.
• •The Ethereum Foundation and Bitcoin developers are also preparing for quantum threats.

Google has announced an accelerated timeline to migrate its systems to post-quantum cryptography (PQC) by 2029, citing rapid advancements in quantum computing technology and the urgency posed by store-now-decrypt-later attacks. This shift comes as the National Institute for Standards and Technology (NIST) plans to phase out RSA algorithms by 2030, with Google urging other organizations to follow suit. The Ethereum Foundation has also set a 2029 target for its quantum security roadmap, recognizing that up to 50% of Bitcoin is vulnerable to quantum threats. The urgency is underscored by the potential for quantum computers to compromise digital signatures, which are critical for transaction security in cryptocurrencies. Google's move reflects a broader industry concern about the implications of quantum computing on existing encryption standards. The company is integrating PQC standards into its Android operating system and Chrome browser, emphasizing the need for proactive measures in the face of evolving threats.
