NBS数据加密标准可被结合进计算机纲,以便保护个人(非公用)文件,确保与本地以及遥远的用户或联机或脱机的联系,保护以防密钥代替,认证系统用户,鉴别数据和提供使用不公开密钥加密算法的数字签名。密钥公证设备给予用户操作一组命令的能力,这些命令用于密钥管理以及数据加密功能。该设备依据密码原理履行公证,该公证封印使发射机与予期的接收机相一致的密钥或通行字。因此,为了解密消息,接收机必须认证它自己并提供该发射机的正确身份。这个特点消除了密钥被替换的危险,必须防止这种危险以达到高度保密。
NBS data encryption standards can be incorporated into computer programs to protect personal (non-public) files, ensure contact with local and remote users either online or offline, protect against key changes, authenticate system users, authenticate data, and provide Digital signature using a non-public key encryption algorithm. The key notary device gives the user the ability to manipulate a set of commands for key management and data encryption. The device performs notarization on the basis of the cryptographic principle, which seals the keys or passwords that make the transmitter consistent with the intended receiver. Therefore, in order to decrypt the message, the receiver must authenticate itself and provide the correct identity of the transmitter. This feature eliminates the danger of the key being replaced and the danger must be prevented to achieve a high degree of confidentiality.
