我们从任意(单阶段)环境中的组合角度研究关联数据验证加密(AEAD)。我们使用不可微性框架来形式化直觉,即“好的”AEAD 方案应该具有可解密的随机密文。在此框架内,我们可以应用不可微性组合定理来表明,在相关安全属性未知或无法提前预测的情况下,此类方案可以提供额外的保障,例如在通用加密库和标准中。
We study Authenticated Encryption with Associated Data (AEAD) from the viewpoint of composition in arbitrary (single-stage) environments. We use the indifferentiability framework to formalize the intuition that a “good” AEAD scheme should have random ciphertexts subject to decryptability. Within this framework, we can then apply the indifferentiability composition theorem to show that such schemes offer extra safeguards wherever the relevant security properties are not known, or cannot be predicted in advance, as in general-purpose crypto libraries and standards.
