description	Lightweight authenticated ciphers are specially designed as authenticated encryption (AE) schemes for resource-constrained devices. Permutation-based lightweight authenticated ciphers have gained more attention in recent years. However, almost all of permutation-based lightweight AE schemes only ensure conventional security, i.e., about c/2-bit security, where c is the capacity of the permutation. This may be vulnerable for an insufficiently large capacity. This paper focuses on the stronger security guarantee and the better efficiency optimization of permutation-based lightweight AE schemes. On the basis of APE series (APE, APERI, APEOW, and APECA), we propose a new improved permutation-based lightweight online AE mode APE+ which supports beyond conventional security and concurrent absorption. Then, we derive a simple security proof and prove that APE+ enjoys at most about minr,c-bit security, where r is the rate of the permutation. Finally, we discuss the properties of APE+ on the hardware implementation.
