【摘要】 采用公钥密码体制RSA算法开发基于RSA的注册码生成器,首先对计算机主机ID生成一个数字签名作为软件注册码,软件运行时再对数字签名进行验证来判断软件的合法性,然后向用户提供软件注册码并发放软件使用权.该注册码生成器可应用于各类应用软件如杀毒软件、操作系统软件、办公软件等,防止软件网上发售或应用过程中被第三方破解而被盗版,这种加密方式能有效地保护软件版权,实用价值较高,能产生一定的经济效益,具有广阔的应用前景.更多还原

【Abstract】 The softwares are generally required to be encrypted for preventing others’ cracking which will cause the intellectual property rights to be infringed and the great economic losses. We develop the registration code generator based on cryptography RSA algorithm,and generate a digital signature for host ID as the software registration code. The digital signature is verified to judge the legitimacy of the software while the software running. It provides the software registration codes to users and issues the rights for using the softwares. The RSA registration code generator can be applied to all kinds of application softwares such as antivirus softwares,operating system softwares,office softwares for preventing the softwares released online or cracked by the third party in the application process. This encryption method can effectively protect the copyrights of software developers,and has high practical value,which can produce certain economic benefits and has broad application prospects.更多还原
