摘　　要： 基于椭圆曲线离散对数问题的难解性,利用二元域上的Koblitz曲线,结合对称加密算法,提出一种适于嵌入式系统的高效签密算法.构建该算法安全模型,对其完整性、可信性、不可伪造性及匿名性进行归约证明.不同设备仿真验证表明,该算法在嵌入式设备中安全可行. A high efficiency signcryption scheme with Koblits curve of binary field and symmetric encryption for the implementation in embedded system was proposed to overcome the hardness of discrete logarithm of ellliptic curve.The security model was also presented.The completeness,confidentiality,unforgeability and ciphertext anonymity of this proposed scheme were discussed in details.The simulation results under various benchmark devices have demonstrated that the efficiency of this new scheme is desirable for embedded system.
