摘　　要：对一类特殊五阶Fibonacci-Lucas序列及其性质进行深入研究,并以五阶Fibonacci-Lucas序列来替代Lucas序列和三阶Fibonacci-Lucas序列,提出基于五阶Fibonacci-Lucas序列类El Gamal的5FLELG公钥密码体制和数字签名方案,验证其正确性和有效性,给出序列项计算方法,并分析体制的安全性和效率。The characteristics of fifth-order Fibonacci Lucas sequence were deeply researched, and based on it 5FLELG publirkey cryptosystem and digital signature scheme were presented which replace the Lucas sequence and 3F-L sequence by fifth-order Fibonacci Lucas sequence. The correctness and validity were studied and the fast computational algorithm for evaluating the term of fifth-order Fibonacci-Lucas sequence was given. At last, efficiency and security analysis of the scheme was provided.
