Security assumption invalidation occurs when the underlying mathematical or computational problem upon which a cryptographic system’s security relies is proven to be solvable. If an adversary gains the ability to efficiently solve this problem, the cryptographic scheme becomes compromised. This event necessitates a re-evaluation and potential replacement of the affected security protocols. It represents a fundamental breakdown in cryptographic assurances.
Context
For digital assets and blockchain, security assumption invalidation is a major concern, especially with the rise of quantum computing, which threatens to invalidate the security assumptions of widely used public-key cryptography. The current focus is on proactively migrating to post-quantum cryptographic algorithms to prevent such an invalidation. This proactive measure is essential to safeguard the integrity and confidentiality of all blockchain-based transactions and stored value.
