MULTICS Security Evaluation: Password and File Encryption Techniques.

摘要

Passwords are stored in enciphered form in the Multics system. There is no clear text listing of the password file. In 1972, as part of a security analysis of Multics, an ESD team successfuly inverted the enciphering algorithm in use on Multics. This report documents the team's efforts. As a result of the ESD analysis, an improved encryption algorithm is now in use on Multics. (Author)
