Experts Urge 256-Bit Encryption Shift Before 2035 Ban on RSA and ECC

256-bit encryption should replace current standards as soon as possible, experts said, warning that RSA and ECC are on track to be disallowed for most applications by 2035.
5- to 10-year migration timelines mean many large enterprises may already be late, especially where legacy, IoT and OT systems use embedded firmware that may be hard or impossible to upgrade.
6,100-qubit machines already exist, and estimates cited in the report say a cryptographically relevant quantum computer could break the encryption underpinning the global economy by the end of the decade.
40-plus QPUs are now sold commercially, but researchers at MIT and IBM said quantum systems still are not enterprise-ready for large-scale cryptanalysis or other broad commercial workloads.
82% of AI-first CEOs are already engaging quantum partners, even as demand for quantum skills has nearly tripled since 2018, underscoring both the business push and the talent gap.

Countdown to Q-Day: Urgent Global Migration to Post-Quantum Cryptography by 2035
Overview
The rapid development of quantum computers poses an urgent and fundamental threat to global digital security, as these machines can efficiently break widely used public-key cryptosystems like RSA and ECC through Shor’s algorithm. This creates a systemic risk and signals the impending failure of classical cryptography. As a result, organizations must act now to protect sensitive data, especially information that needs to remain confidential beyond 2032-2035, since the transition to post-quantum cryptography is both extensive and time-consuming. Delaying action increases the risk that adversaries will harvest and store encrypted data today, intending to decrypt it once quantum capabilities mature.
