Modern cryptography seeks to guarantee the information confidentiality and\nprevent unauthorized people from having access to it. These principles may be\napplied in portable devices that require the protection of the information that has\nbeen stored and processed. These types of applications require certain design\ncommitments that are achieved using high-performance hardware and the\nimplementation of light-weight algorithms, specifically the Present algorithm.\nThis method uses a block-based light encryption scheme which is relatively new,\nthat has not been infringed at the present date, with features that make it appealing\nfor an implementation on reconfigurable architectures such as FPGA. This work\npresents the study, design, implementation and tests of this encryption algorithm.
