Abstract


This paper presents a new user authentication scheme, which  does not  require a management file for user’s password. It has a high security, realizing the authentication of a large number of uses by a single public key. This paper presents a access matrix control by  a real number C between 0 and 1.  Finally, the paper proposes an access control scheme in distributed database with a single key, which has security of public key Merkle-Knapsack.
