Attacks on the HKM/HFX Cryptosystem

چکیده
The HKM / HFX cryptosystem is proposed for standardization at the ITU Telecommunication Standardization Sector Study Group 8. It is designed to provide authenticity and colffidentiality of FAX messages at a commercial level of security. In addition, the HKM / HFX cryptosystem is designed for unrestricted export. This paper contains the results of an analysis of the HKM/HFX cryptosystem. Eleven attacks and their complexities are described in full detail. The analytic results show that the security provided by the HKM / HFX cryptosystem is not high enough to meet the requirements for an internationM standard of the ITU, even with the additional feature of free exportability.

Improving the Rao-Nam secret key cryptosystem using regular EDF-QC-LDPC codes
This paper proposes an efficient joint secret key encryption-channel coding cryptosystem, based on regular Extended Difference Family Quasi-Cyclic Low-Density Parity-Check codes. The key length of the proposed cryptosystem decreases up to 85 percent using a new efficient compression algorithm. Cryptanalytic methods show that the improved cryptosystem has a significant security advantage over Ra...
متن کاملModified GPT Cryptosystem for Information Network Security
To provide information security in network we use the public key GPT (Gabidulin–Paramonov–Tretiyakov) cryptosystem based on rank codes. This cryptosystem was the subject of several attacks. Some of them were structural attacks, others were decoding attacks. In our opinion the most dangerous are structural attacks because decoding attacks can be prevented by proper choice of parameters. To preve...
متن کاملMathematical Attacks on RSA Cryptosystem
In this paper some of the most common attacks against Rivest, Shamir, and Adleman (RSA) cryptosystem are presented. We describe the integer factoring attacks, attacks on the underlying mathematical function, as well as attacks that exploit details in implementations of the algorithm. Algorithms for each type of attacks are developed and analyzed by their complexity, memory requirements and area...
متن کاملCryptanalytic attacks on the multiplicative knapsack cryptosystem and on Shamir's fast signature scheme
The basic Merkle-Hellman additive trapdoor knapsack public-key cryptosystem was recently shown to be insecure, and attacks have also been developed on stronger variants of it, such as the Graham-Shamir system and the iterated knapsack cryptosystem. This paper shows that some simple variants of another Merkle-Hellman system, the multiplicative knapsack cryptosystem, are insecure. It is also show...
متن کاملDifferential Fault Attacks on Elliptic Curve Cryptosystems
In this paper we extend the ideas for differential fault attacks on the RSA cryptosystem (see [4]) to schemes using elliptic curves. We present three different types of attacks that can be used to derive information about the secret key if bit errors can be inserted into the elliptic curve computations in a tamper-proof device. The effectiveness of the attacks was proven in a software simulatio...
