Tóm tắt

Tóm tắt— Trong bài báo này, nhóm tác giả đề xuất tầng tuyến tính an toàn và hiệu quả trong cài đặt để hướng tới việc xây dựng mã khối kích thước 256-bit có tên là FLC. Cụ thể, nhóm tác giả đã sinh ra ma trận MDS kích thước 8×8 có dạng lũy thừa của ma trận đồng hành trên trường hữu hạn. Khi xem xét sử dụng ma trận này trong xây dựng mã khối 256-bit có cấu trúc FLC, nhóm tác giả thực hiện đánh giá khả năng cài đặt của quá trình mã hóa/giải mã trên nhiều nền tảng khác nhau. Các kết quả thực nghiệm chỉ ra rằng cài đặt của mã khối với đề xuất này hoàn toàn phù hợp để tích hợp trong các ứng dụng thực tế.

Abstract— In this paper, we propose a secured and efficient linear diffusion layer that suitable for block cipher with 256-bit block size named FLC.  Specifically, we have generated an 8×8 MDS matrix that has the power of a companion matrix over a finite field. We also perform a performance evaluation of the encryption/decryption process on various platforms. Our experimental results show that block cipher with our proposed linear diffusion layer is perfectly suitable for real life applications.
