Definition ∞ Plain Model Cryptography refers to cryptographic schemes whose security proofs are based directly on standard cryptographic assumptions without requiring idealized assumptions about components like random oracles. This approach provides a higher degree of theoretical security assurance because it avoids relying on abstract, non-realizable constructs. It aims for proofs of security that hold in the real world.
Context ∞ The debate between plain model cryptography and schemes relying on random oracle models is a recurring theme in cryptographic research, with implications for the foundational security of blockchain protocols. While random oracle models can simplify proofs, plain model proofs are generally considered more robust against future attacks. Advances in zero-knowledge proofs often seek plain model security guarantees to bolster trust.
