A password authentication scheme over insecure networks

Public-key/private-key hybrid key agreements and authentication protocols which maintain privacy of conversation and location information, and deter usage fraud, are presented. These protocols are optimized for low complexity in the portable unit and network infrastructure. The basic cryptographic techniques are described, and some complexity information obtained from these laboratory experiments and from other sources are presented. The three public-key protocols described have differing levels of security and complexity: and the tradeoffs are discussed. Because of the complexity concerns mentioned above, the public-key protocols are compared to a representative private-key approach in the areas of both security and computational complexity. >

Privacy and authentication on a portable communications system

A method for achieving mutual authentication and session key agreement between a first party (12) that has a minimal computational resources and a second party (18) that has substantial computational resources uses a modular square root operation for certificate authentication and key distribution and an ELGamal, NIST DSS, or other efficient signature operation for obtaining the signature of a message. The second party (18) is connected to a switching system (23) in a central office (22).

Two-way public key authentication and key agreement for low-cost terminals

The invention provides a software construct, herein termed a Web service container, for managing Web services at a network node and an adaptive model for the dynamic configuration of a plurality of Web service containers distributed throughout a network, such as the Internet or an intranet, in a software and hardware platform-independent manner. Containers can communicate with each other via the network to determine contextual information such as the identity of each other, the capabilities of each other, the operating system or platforms of each others, the contents of the container (i.e., the available Web services at that location), etc. By providing a container framework and the ability to exchange contextual information, the present invention allows servers as well as clients to dynamically exchange Web services software as well as contextual information, such as current workload, so that servers and clients are virtually limitlessly reconfigurable based on context.

A Password Authentication Method for Contents Communications on the Internet

A new password-based authentication system CINON is proposed for use in communications and computer systems It employs a one-way function to perform the required authentication of communicating users CINON maintains its security in spite of a wiretap or the theft of a password file, and it is not necessary to replace the correspondents' public passwords CINON can be realized with only a few computations



This paper evaluates the CINON system and compares it with the Lamport authentication system, an earlier system which uses a one-way data transformation In comparison with the Lamport system, CINON's execution speed is faster by a factor of perhaps several hundred to a thousand

This paper discusses the design of the fast data encipherment algorithm (FEAL). FEAL is a conventional encipherment algorithm using the same key for enciphering and deciphering. It is a block cipher algorithm which produces 64 bit ciphertext from 64 plaintext, using a 64-bit key. The main feature of the cipher processing in FEAL is that it is based on 8-bit data manipulations such as addition with modulo 256, and data cycle and data transfer commands for 1-byte. The program performance of FEAL is improved greatly compared with that of DES. The security of FEAL is based on the characteristic value representing the trace of the plaintext and ciphering key remaining in the ciphertext, as well as on the algorithm structure.
