：随着数据加密技术的不断发展，计算机处理能力的不断增强，以往许多被认为比较安全的数据加密算法，都相继被破解。针对这些情况，此文首先详细分析了私钥加密算法、公钥加密算法、数字签名技术和哈希函数的特点以及在使用过程中需要注意的问题，然后提出了一种综合使用私钥、公钥、数字签名等技术的增强型加密服务架构。此架构利用公钥算法的特点为私钥算法生成密钥，有效降低了因私钥泄露而导致的威胁，利用数字签名技术可有效降低数据被非法篡改的可能性。

With the continuous development of data encryption technology and the continuous enhancement of computer processing ability, in the past, many more secure data encryption algorithms have been considered cracked. To solve these problems, this paper first analyzes the characteristics of the private key encryption algorithm, public key encryption algorithm, digital signature technology and hash function, as well as the need to pay attention to the problem in the use of the process. Then the author puts forward an enhanced encryption service architecture making comprehen-sive use of private key, public key, digital signature and other technology. This architecture uses the characteristics of public key algorithm to generate the key to private key encryption algorithm, which can reduce the threat caused by private key leakage, and effectively reduce the data illegal tampering by using digital signature technology.
