On the Use of Encryption in Cryptographic Protocols
نویسندگان
چکیده
In the past few years the International Organisation for Standardization (ISO) and International ElectroTechnical Commission (IEC) have been jointly developing several standards for entity authenti-cation and/or encryption key exchange. Some of the mechanisms proposed use a symmetric block encryption algorithm, in a particular mode of operation, to achieve security. In this paper a general property of the algorithm is explained. It is shown that some of the protocols in the ISO/IEC draft documents for standardisation are vulnerable to an attack which exploits this property.

RSPAE: RFID Search Protocol based on Authenticated Encryption
Search protocols are among the main applications of RFID systems. Since a search protocol should be able to locate a certain tag among many tags, not only it should be secure against RFID threats but also it should be affordable. In this article, an RFID-based search protocol will be presented. We use an encryption technique that is referred to as authenticated encryption in order to boost the ...

Nowadays, achieving desirable and stable security in networks with national and organizational scope and even in sensitive information systems, should be based on a systematic and comprehensive method and should be done step by step. Cryptography is the most important mechanism for securing information. a cryptographic system consists of three main components: cryptographic algorithms, cryptogr...
متن کاملDeciding the Security of Protocols with Commuting Public Key Encryption
Many cryptographic protocols and attacks on these protocols make use of the fact that the order in which encryption is performed does not affect the result of the encryption, i.e., encryption is commutative. However, most models for the automatic analysis of cryptographic protocols can not handle such encryption functions since in these models the message space is considered a free term algebra...
متن کاملDifferential Power Analysis: A Serious Threat to FPGA Security
Differential Power Analysis (DPA) implies measuring the supply current of a cipher-circuit in an attempt to uncover part of a cipher key. Cryptographic security gets compromised if the current waveforms obtained correlate with those from a hypothetical power model of the circuit. As FPGAs are becoming integral parts of embedded systems and increasingly popular for cryptographic applications and...
متن کاملA Performance Survey of Meta-Heuristic And Brute-Force Search Algorithms to Cryptanalysis The SDES Encryption Algorithm
For many years, cryptanalysis has been considered as an attractive topic in jeopardizing the security and resistance of an encryption algorithm. The SDES encryption algorithm is a symmetric cryptography algorithm that performs a cryptographic operation using a crypt key. In the world of encryption, there are many search algorithms to cryptanalysis. In these researches, brute force attack algori...
