Users communicate with each other or the ability to transmit messages in secrecy without any prior exchange of a secret key, and the ability to imple- ment digital signatures that are legally binding. Public- key encryption alone, however, does not guarantee either message secrecy or signatures. Unless the keys are ade- quately protected, a penetrator may be able to read en- crypted messages or forge signatures. This article discusses the problem ofprotecting keys in a nationwide network using public-key cryptography for secrecy and digital signatures. Particular attention is given to detecting and recovering from key compromises, especially when a high level of security is required. Public-key cryptosystems The concept of public-key cryptography was intro- duced by Diffie and Hellman in 1976.1 The basic idea is that each user A has a public key EA, which is registered in a public directory, and a private key DA, which is known only to the user.

  • NSS: an NTRU Lattice –Based Signature Scheme
    ISSN(Online) : 2319 - 8753 ISSN (Print) : 2347 - 6710 International Journal of Innovative Research in Science, Engineering and Technology (An ISO 3297: 2007 Certified Organization) Vol. 4, Issue 4, April 2015 NSS: An NTRU Lattice –Based Signature Scheme S.Esther Sukila Department of Mathematics, Bharath University, Chennai, Tamil Nadu, India ABSTRACT: Whenever a PKC is designed, it is also analyzed whether it could be used as a signature scheme. In this paper, how the NTRU concept can be used to form a digital signature scheme [1] is described. I. INTRODUCTION Digital Signature Schemes The notion of a digital signature may prove to be one of the most fundamental and useful inventions of modern cryptography. A digital signature or digital signature scheme is a mathematical scheme for demonstrating the authenticity of a digital message or document. The creator of a message can attach a code, the signature, which guarantees the source and integrity of the message. A valid digital signature gives a recipient reason to believe that the message was created by a known sender and that it was not altered in transit. Digital signatures are commonly used for software distribution, financial transactions etc. Digital signatures are equivalent to traditional handwritten signatures. Properly implemented digital signatures are more difficult to forge than the handwritten type. 1.1A digital signature scheme typically consists of three algorithms A key generationalgorithm, that selects a private key uniformly at random from a set of possible private keys. The algorithm outputs the private key and a corresponding public key. A signing algorithm, that given a message and a private key produces a signature.

    > DOCUMENT SIGNING > eID VALIDATION > SIGNATURE VERIFICATION > TIMESTAMPING & ARCHIVING > APPROVAL WORKFLOW Basics of Digital Signatures & PKI This document provides a quick background to PKI-based digital signatures and an overview of how the signature creation and verification processes work. It also describes how the cryptographic keys used for creating and verifying digital signatures are managed. 1. Background to Digital Signatures Digital signatures are essentially “enciphered data” created using cryptographic algorithms. The algorithms define how the enciphered data is created for a particular document or message. Standard digital signature algorithms exist so that no one needs to create these from scratch. Digital signature algorithms were first invented in the 1970’s and are based on a type of cryptography referred to as “Public Key Cryptography”. By far the most common digital signature algorithm is RSA (named after the inventors Rivest, Shamir and Adelman in 1978), by our estimates it is used in over 80% of the digital signatures being used around the world. This algorithm has been standardised (ISO, ANSI, IETF etc.) and been extensively analysed by the cryptographic research community and you can say with confidence that it has withstood the test of time, i.e. no one has been able to find an efficient way of cracking the RSA algorithm. Another more recent algorithm is ECDSA (Elliptic Curve Digital Signature Algorithm), which is likely to become popular over time. Digital signatures are used everywhere even when we are not actually aware, example uses include: Retail payment systems like MasterCard/Visa chip and pin, High-value interbank payment systems (CHAPS, BACS, SWIFT etc), e-Passports and e-ID cards, Logging on to SSL-enabled websites or connecting with corporate VPNs.

  • A Non-Exchanged Password Scheme for Password-Based Authentication in Client-Server Systems

Hussain and 2Hussein Al-Bahadili 1Faculty of IT, Applied Science University, P.O. Box 22, Amman 11931, Jordan 2Faculty of Information Systems and Technology, Arab Academy for Banking and Financial Sciences, P.O. Box 13190, Amman 11942, Jordan Abstract: The password-based authentication is widely used in client-server systems. This research presents a non-exchanged password scheme for password-based authentication. This scheme constructs a Digital Signature (DS) that is derived from the user password. The digital signature is then exchanged instead of the password itself for the purpose of authentication. Therefore, we refer to it as a Password-Based Digital Signature (PBDS) scheme. It consists of three phases, in the first phase a password-based Permutation (P) is computed using the Key-Based Random Permutation (KBRP) method. The second phase utilizes P to derive a Key (K) using the Password-Based Key Derivation (PBKD) algorithm. The third phase uses P and K to generate the exchanged DS. The scheme has a number of features that shows its advantages over other password authentication approaches.

  • Fault Analysis of the Ntrusign Digital Signature Scheme
    Cryptogr. Commun. (2012) 4:131–144 DOI 10.1007/s12095-011-0061-3 Fault analysis of the NTRUSign digital signature scheme Abdel Alim Kamal · Amr M. Youssef Received: 11 December 2010 / Accepted: 14 December 2011 / Published online: 6 January 2012 © Springer Science+Business Media, LLC 2012 Abstract We present a fault analysis of the NTRUSign digital signature scheme. The utilized fault model is the one in which the attacker is assumed to be able to fault a small number of coefficients in a specific polynomial during the signing process but cannot control the exact location of the injected transient faults. For NTRUsign with parameters (N, q = pl, B, standard, N ), when the attacker is able to skip the norm-bound signature checking step, our attack needs one fault, ≈ − 1 (( )t) succeeds with probability 1 p and requires O qN steps when the number of faulted polynomial coefficients is upper bounded by t. The attack is also applicable to NTRUSign utilizing the transpose NTRU lattice but it requires double the number of fault injections. Different countermeasures against the proposed attack are investigated.

  • Practical Lattice-Based Digital Signature Schemes J
    Practical Lattice-based Digital Signature Schemes J. Howe1, T. Pöppelmann2, M. O’Neill1, E. O’Sullivan1, T. Güneysu2 1 Centre for Secure Information Technologies (CSIT), Queen’s University Belfast, UK 2Horst Görtz Institute for IT-Security, Ruhr-University Bochum, Germany Abstract: Among the various post-quantum techniques that exist (such as multivariate, code or hash-based), the most promising is lattice-based cryptography, which has become a very viable alternative to number-theoretic cryptography. Its main advantage is that it allows for extended functionality and is, at the same time, more efficient for the basic primitives of public-key encryption and digital signatures. The focus of this presentation will be to survey recent developments in lattice-based digital signature schemes and in particular practical schemes that have been shown to improve upon the performance of equivalent RSA designs. Propositions for future research areas that are essential for the continued development of lattice-based cryptography will also be discussed. 1 Introduction With the onset of quantum computers ever looming, the computational power it could provide would cause instant insecurity to many of today’s universally used cryptographic schemes by virtue of Shor’s [1] algorithm. Specifically, schemes based on the discrete-logarithm problem or number-theoretic hard problems, which subsume almost all public-key encryption schemes used on the Internet, including elliptic-curve cryptography (ECC), RSA and DSA would be vulnerable. Accordingly, this has motivated the post-quantum era of cryptography, which refers to the construction of cryptographic algorithms to withstand quantum reductions. Amongst many important areas in post-quantum research (such as multivariate, code or hash-based) lattice-based cryptography is disputably the most auspicious.
