摘要
随着加密数字货币的崛起,新兴的区块链技术成为了研究热点,由于区块链技术的去中心化和信任机制的提出,数字签名显得尤为重要。为提高数字签名的安全性,文中在交易过程中提出了一种基于高级加密标准(AES)和椭圆曲线密码算法(ECC)的混合加密算法,双方经过Diffie-Hellman(DH)算法管理密钥的方法实现签名,使其各自检验对方的身份。既实现了对称加密技术运行速度快的特点,又实现了非对称加密密钥的安全性,同时也使签名更具真实性和可靠性。
With the rise of encrypted digital money,the emerging blockchain technology has become a research hotspot,because the block chain technology to the centralization and trust mechanism proposed,digital signature is particularly important. In order to improve the security of digital signature,a hybrid encryption algorithm based on Advanced Data Encryption Standard（ AES） and Elliptic Curve Cryptography（ ECC） is proposed in the process. The two sides pass the Diffie-Hellman（ DH） algorithm to manage the key The way to achieve the signature,so that each of their own identity. Not only achieved the characteristics of symmetric encryption technology running fast,but also to achieve the security of the asymmetric encryption key,but also make the signature more authenticity and reliability.
