"SEA - Scalable Encryption Algorithm is a block cipher based symmetric encryption scheme, specially designed for resource constrained devices. SEA proposes low computational encryption routines (i.e. less code size, memory and power) for processors with a restricted instruction set. SEA is parametric with plain-text, key and microprocessor size, and meant for efficient combination of encryption/decryption and key derivation. The performance of modified SEA using efficient architectures of 2b and 2b-1 modular adders in a Field Programmable Gate Array (FPGA) device is investigated. In this paper, an iterative based loop design of the block cipher is first implemented on FPGA."
