Most known Sbox Advanced Encryption Standard implementations aim at minimizing chip covered area or achieving high throughput, and usually power consumption is a secondary metric of their cost. However, the need for low power applications with strict chip covered area constrains is great especially in mobile devices. In this paper low power architectures in limited area resources are proposed for Sbox, the basic cryptographic primitive of AES. Those architectures support encryption and decryption operation modes. In our proposed implementations, retaining a small chip covered area cost, hardware techniques for low power design, such as re-ordering of the components,
