摘要

分析了NIST轻量级加密项目标准化轻量级认证加密的两个最终入围者Romulus-N和GIFT-COFB的非滥用弹性（NMRL）安全性。NMRL，由Ashur等人介绍。在CRYPTO 2017上，这是一个从更强大的、非滥用抵抗概念转变而来的宽松的安全概念。作者证明了Romulus-N和GIFT-COFB具有随机误用弹性。对于Romulus-N，显示了相对于非ce重复具有优美退化的完美私密性（NMRL-PRIV）和N/2位真实性（NMRL-AUTH）。对于GIFT-COFB，给出了NMRL-PRIV和NMRL-AUTH概念的n/4位安全性。

Nonce-misuse resilience of Romulus-N and GIFT-COFB

Nonce-misuse resilience (NMRL) security of Romulus-N and GIFT-COFB is analysed, the two finalists of NIST Lightweight Cryptography project for standardising lightweight authenticated encryption. NMRL, introduced by Ashur et al. at CRYPTO 2017, is a relaxed security notion from a stronger, nonce-misuse resistance notion. The authors have proved that Romulus-N and GIFT- COFB have nonce-misuse resilience. For Romulus-N, the perfect privacy (NMRL-PRIV) and n/2-bit authenticity (NMRL-AUTH) with graceful degradation with respect to nonce repetition are showed. For GIFT-COFB, n/4-bit security for both NMRL-PRIV and NMRL-AUTH notions is showed.
