Questions
How will you achieve the 2026 strategic goals?
Few main activities:
Both Post-Quantum Cryptography (PQC TG) and High-Assurance Cryptography (HAC TG) operate under the Crypto SIG umbrella. The SIG consensus is that both are in “feature freeze”. HAC and PQC have ratification plans (under approval) that should conclude by the end of the year.
The memory encryption (“MEC”) work is progressing (mainly under Security HC), and the role of the Cryptography SIG is to provide expertise and analysis on cryptographic standards, algorithms, and modes of operation based on the latest research.
What gap analyses will you deliver to the TSC in 2026?
China “New Crypto” Gaps: We are engaging RVI membership in China to understand the implications of the new Chinese cryptography competition and Chinese PQC efforts.
Memory Encryption Gaps: Additional analysis related to memory encryption features, and the relevant security model.
