A Modular-based Approach to Design Secure Protocol

Published Jan 1, 2006• 1 citation
OpenAlex

Abstract

The present methods to design secure protocol have the following characters:abstract,the narrow application range,complexity,and non-system.This paper presents a novel approach,which firstly combines the implementation modules of protocol type and secure properties to construct the original protocol,and then according to protocol requirements,perfects it to form the final protocol.The approach can be applied to all secure protocols,and it is easier for people to design secure protocol,and to implement the auto-design of secure protocol.At last,the paper illustrates the two-part key establishment protocol to show how one use this approach to design secure protocol.

General Cryptographic Protocols

Oded Goldreich

The design of secure protocols that implement arbitrarily desired functionalities is a major part of modern cryptography. Taking the opposite perspective, the design of any cryptographic scheme may be viewed as the design of a secure protocol for implementing a suitable functionality. Still, we believe that it makes sense to differentiate between basic cryptographic primitives (which involve little interaction) like encryption and signature schemes, on the one hand, and general cryptographic protocols, on the other hand. In this chapter we consider general results concerning secure multi –party computations, where the two –party case is an important special case. In a nutshell, these results assert that one can construct protocols for securely computing any desirable multi–party functionality (see the following terminology). Indeed, what is striking about these results is their generality, and we believe that the wonder is not diminished by the (various alternative) conditions under which these results hold. Our focus on the general study of secure multi–party computation (rather than on protocols for solving specific problems) is natural in the context of the theoretical treatment of the subject matter. We wish to highlight the importance of this general study to practice. Firstly, this study clarifies fundamental issues regarding security in a multi–party environment. Secondly, it draws the lines between what is possible in principle and what is not. Thirdly, it develops general techniques for designing secure protocols. And last, sometimes it may even yield schemes (or modules) that may be incorporated in practical systems.

A Modular Approach to the Design and Analysis of Authentication and Key Exchange Protocols.

Mihir Bellare Y, Ran Canetti, Hugo Krawczyk

We present a general framework for constructing and analyzing authentication protocols in realistic models of communication networks. This framework provides a sound formalization for the authentication problem and suggests simple and attractive design principles for general authentication and key exchange protocols. The key element in our approach is a modular treatment of the authentication problem in cryptographic protocols; this applies to the definition of security, to the design of the protocols, and to their analysis. In particular, following this modular approach, we show how to systematically transform solutions that work in a model of idealized authenticated communications into solutions that are secure in the realistic setting of communication channels controlled by an active adversary. Using these principles we construct and prove the security of simple and practical authentication and key-exchange protocols. In particular, we provide a security analysis of some well-known key exchange protocols (e.g. authenticated Diffie-Hellman key exchange), and of some of the techniques underlying the design of several authentication protocols that are currently being

Secure multi-party key establishment

Chih-Hung Li

For a secure communication through the public network, cryptographic encryption must be applied. The key establishment issue is the most important part in cryptographic encryption. Only the legitimate principals who have the key can encrypt messages and decrypt cryptograms. A secure multi-party communication held through the public network can only take place after a multi-party key establishment protocol has been executed. The multi-party key establishment protocol is designed so that the principals can receive a common key and use it to securely exchange the messages.\nIn this thesis, the secure multi-party key establishment protocols are discussed. W e start from investigating properties of two-party key establishment protocols such as motivation of using session key, adversaries in the protocols, attacks of the protocol and security analysis of the protocol. Then we give the requirements of a multi-party key establishment protocol and summarize about what should be considered in designing a multi-party key establishment protocol. After that we review some of the previous proposed multi-party key establishment protocol. The existing multi-party key establishment protocols are either impractical ( not efficient enough) or missing some important security goals such as authentication of principals. Three new protocols are proposed in this thesis. The first protocol addresses how to hold a conference for members of two hierarchical groups in an efficient way. The message broadcasting is used to reduce the cost of secure message transport.\nThe second and the third protocols manage the authentication problem by using a secret sharing scheme. We replace the principal authentication with the group authentication so that the computational overhead and communication overhead will be reduced especially in reuse of the protocol for new communication. Again, message broadcasting is used for replacing the expansive secure communication channel.\nPart of this thesis appeared in ACSC'99(Australian Computer Science Conference) and ACISP'99(Australian Conference of Information Security and Privacy).

Converters for Designing Applied Cryptographic Protocols

Zhao Huawei, Jing Qin, Fang Zhifeng

Two modularized, non-interactive converters are proposed to design applied cryptographic protocols. The converters are based on the refined scheme given by Wenbo Mao, and can transform protocols secure in the ideal model into those secure in the real model. Because the converters are modularized, once proved secure, they can be widely reused in many protocols. And in contrast to BCK-authenticator, the converters have the following advantages: 1, Because of the character of non-interactivity, the transformed protocols outputted by the converters have higher performance than those protocols outputted by BCK-authenticator. 2, The converters can transform some symmetric-key protocols that can not be transformed by BCK-authenticator. 3, The converters have algorithms, which can help to realize automatic transformation.

Fail-Stop Protocols: An Approach to Designing Secure Protocols (Preprint)

Gong, Li, Paul F. Syverson

We present a methodology to facilitate the design and analysis of secure cryptographic protocols. We advocate the general approach, and a new avenue for research, of restricting protocol designs to well-defined practices, instead of ever increasing the complexity of protocol security analysis mechanisms to deal with every newly discovered attack and the endless variations in protocol construction. In particular, we propose a novel notion of a fail-stop protocol, which automatically halts in response to any active attack that interferes with protocol execution, thus reducing protocol security analysis to that of passive attacks only. We suggest types of protocols that are fail-stop, outline some proof techniques for them, and use examples to illustrate how the notion of a fail-stop protocol can make protocol design easier and can provide a more solid basis for some available protocol analysis methods.
