TLDR
In this paper, an improved method and apparatus for authenticating message packets to prevent forgery of message packets is presented. But the method requires the client to generate a message signature based on the session key and the message itself.Abstract:
The present invention provides an improved method and apparatus for authenticating message packets to prevent forgery thereof. A server processes a client request and generates a response message. A message signature, which is generated using the session key and the message itself, is appended to the message to create an appended message. The server sends the appended message to the client. At the same time that the server works on the client request, the client predicts the response message and calculates a predicted message signature based on the session key and the predicted message. After receiving the appended message, the client strips the message signature from the appended message and compares it to the predicted message signature. If the two signatures match, the received message packet is authenticated.read more

Method and system for access to automatically synchronized remote files
TL;DR: In this paper, a method and system for the simple, fast, and effective maintenance of consistent data files across a multiplicity of computer systems, which functionality is useful in collaborative work, effective backup, and disaster recovery.
Patent
Simple, secure login with multiple authentication providers
TL;DR: A secure distributed single-login authentication system comprises a client and a server as mentioned in this paper, where the client collects a user name and password from a user and tests that user name/password at a variety of potential authentication servers to check where the login is valid.

Authority delegation with secure operating system queues
TL;DR: In this paper, the authors present a system for delegating security rights to Java servlets and other executable tasks by using secure operating system queues, where the servlet submitted by a given user runs in the context of that user's rights.

A method for packet authentication in the presence of network address translations and protocol conversions
TL;DR: In this paper, the transformations occurring to a packet en route between the sending node and the receiving node are discovered dynamically (1003, 1004), and the discovered transformations are checked to be acceptable based on the applicable security policy, and the dynamically discovered, acceptable transformations are compensated for (1004, 1006) before authenticating packets transmitted from the sender to the receiver.

The MD4 Message-Digest Algorithm
TL;DR: The MD4 message digest algorithm takes an input message of arbitrary length and produces an output 128-bit "fingerprint" or "message digest", in such a way that it is (hopefully) computationally infeasible to produce two messages having the same message digest, or to produce any message having a given prespecified target message digest.

Method and apparatus for privacy and authentication in wireless networks
Whitfield Diffie,Ashar Aziz +1 more
TL;DR: In this paper, a secure wireless communication link between a mobile nomadic device and a base computing unit is proposed, in which a mobile sends a host certificate (Cert -- Mobile) to the base along with a randomly chosen challenge value (CH1) and a list of supported shared key algorithms ("SKCS").
Patent
Digital signature algorithm
TL;DR: In this paper, a method for generating and verifying a digital signature of a message m is presented, which requires a pair of corresponding public and secret keys (y and x) for each signer, as well as the pair of private values (r and k) generated for each message by the signer.
Patent
Method and apparatus for authentication of client server communication
TL;DR: In this article, a method and apparatus for message packet authentication to prevent the forging of message packets is presented, where a portion of the message digest, referred to as the signature, is then appended to the actual message when it is sent over the wire.

Method for checking the integrity of a program or data, and apparatus for implementing this method
Michel Ugon,Andre Oisel +1 more
TL;DR: In this article, a method and apparatus for checking the integrity of a message such as a program and/or data against an original message supposed to correspond to it is presented, where at least one signature (S1, S2,... Sm) of this part is calculated and memorized in a memory area of a portable object.
