数据库管理系统(DBMS)的数据通信数据库用户现在已有机会使用刚由应用数据研究公司(ADR)发表的与国家标准局的数据加密标准(DES)有关的软件来保护其敏感的信息。这种数据加密组件可被看作用一种适当的软件仿效DES中的算法来对数据库中的信息有选择地加密和解密。安全数据是计算计划公司协同美国政府提出来的。密码术为可卸存贮介质上存贮的信息提供了几乎是绝对的保护,ADR的一位发言人声称:“如果用得聪明”,它的费用比一些较为传统的控制表法要少。他还补充说:数据通信/数据库是第
Data Communication Database Users of Database Management Systems (DBMSs) now have the opportunity to protect their sensitive information using software just published by Applied Data Research Corporation (ADR) related to the National Institute of Standards and Technology’s Data Encryption Standard (DES). This data encryption component can be thought of as a suitable software that emulates the algorithms in DES to selectively encrypt and decrypt information in the database. Security data is calculated by the planning company in collaboration with the U.S. government. Cryptography provides almost absolute protection of the information stored on removable storage media, and a spokesman for ADR claims that “if used wisely,” it costs less than some of the more traditional control lists. He also added: data communications / database is the first
