The ongoing NIST lightweight standardization process explicitly puts forward a requirement of side-channel security, which has renewed the interest for Authenticated Encryption schemes (AEs) with light(er)-weight side-channel secure implementations. To address this challenge, we investigate the leakageresistance of a generic duplex-based stream cipher, and prove the classical bound, i.e., ≈ 2 c/2 , under an assumption of non-invertible leakage. Based on this, we propose a new 1-pass AE modedblp:journals/iacr/GuoPPS19 fatcat:tyh5rkjpnveybmk4sgft7awytq
