In this paper, a new lightweight authenticated encryption scheme that uses a lightweight block cipher is introduced. The cipher supports flexible key sizes starting from 128 bits, with the increment of 64 bits. Security evaluation shows that the cipher passed the evaluation of algebraic, differential and linear cryptanalysis which proved after 11 rounds, the attacker has no advantage over brute force attack. Furthermore, performance analysis is evaluated based on throughput (Mbps), latency (cycle) and area estimation (gate equivalence). Hardware implementations of the cipher require approximately 2526 GE with a throughput of 118Kbps running on Intel i5-8250 CPU using Python implementation
