Handbook of Applied Cryptography

Gigantically comprehensive and carefully researched, Security Engineering makes it clear just how difficult it is to protect information systems from corruption, eavesdropping, unauthorized use, and general malice. Better, Ross Anderson offers a lot of thoughts on how information can be made more secure (though probably not absolutely secure, at least not forever) with the help of both technologies and management strategies. His work makes fascinating reading and will no doubt inspire considerable doubt--fear is probably a better choice of words--in anyone with information to gather, protect, or make decisions about. Be aware: This is absolutely not a book solely about computers, with yet another explanation of Alice and Bob and how they exchange public keys in order to exchange messages in secret. Anderson explores, for example, the ingenious ways in which European truck drivers defeat their vehicles' speed-logging equipment. In another section, he shows how the end of the cold war brought on a decline in defenses against radio-frequency monitoring (radio frequencies can be used to determine, at a distance, what's going on in systems--bank teller machines, say), and how similar technology can be used to reverse-engineer the calculations that go on inside smart cards. In almost 600 pages of riveting detail, Anderson warns us not to be seduced by the latest defensive technologies, never to underestimate human ingenuity, and always use common sense in defending valuables. A terrific read for security professionals and general readers alike. --David Wall Topics covered: How some people go about protecting valuable things (particularly, but not exclusively, information) and how other people go about getting it anyway. Mostly, this takes the form of essays (about, for example, how the U.S. Air Force keeps its nukes out of the wrong hands) and stories (one of which tells of an art thief who defeated the latest technology by hiding in a closet). Sections deal with technologies, policies, psychology, and legal matters.

Security Engineering: A Guide to Building Dependable Distributed Systems

This paper tackles a major privacy concern in current location-based services where users have to continuously report their locations to the database server in order to obtain the service. For example, a user asking about the nearest gas station has to report her exact location. With untrusted servers, reporting the location information may lead to several privacy threats. In this paper, we present Casper1; a new framework in which mobile and stationary users can entertain location-based services without revealing their location information. Casper consists of two main components, the location anonymizer and the privacy-aware query processor. The location anonymizer blurs the users' exact location information into cloaked spatial regions based on user-specified privacy requirements. The privacy-aware query processor is embedded inside the location-based database server in order to deal with the cloaked spatial areas rather than the exact location information. Experimental results show that Casper achieves high quality location-based services while providing anonymity for both data and queries.

Applied cryptography, second edition : protocols, algorithms,and source code in C

This paper describes a new public-key cryptosystem based on the hardness of computing higher residues modulo a composite RSA integer. We introduce two versions of our scheme, one deterministic and the other probabilistic. The deterministic version is practically oriented: encryption amounts to a single exponentiation w.r.t. a modulus with at least 768 bits and a 160-bit exponent. Decryption can be suitably opti- mized so as to become less demanding than a couple RSA decryptions. Although slower than RSA, the new scheme is still reasonably compet- itive and has several specific applications. The probabilistic version ex- hibits an homomorphic encryption scheme whose expansion rate is much better than previously proposed such systems. Furthermore, it has se- mantic security, relative to the hardness of computing higher residues for suitable moduli.

A new public key cryptosystem based on higher residues

In this paper we propose a novel solution to the problem of providing trusted third party services, such as the management of cryptographic keys for end-to-end encryption, in a way that meets legal requirements for warranted interception. Also included is a discussion of what might be a reasonable set of requirements for international provision of such services, as well as some analysis of the cryptographic properties of the architecture and how it might operate in practice.

A Proposed Architecture for Trusted Third Party Services

In an ideal secret sharing scheme, the access structure is uniquely determined by its minimal sets \Delta_s. The purpose of this paper is to characterise \Delta_s. We introduce the concept of strong connectivity and show that under this equivalence relation, an ideal secret sharing scheme decomposes into threshold schemes. We also give a description of the minimal sets that span the strong connectivity classes. As a result we obtain a necessary condition on the types of subsets that are allowed in an ideal access structure as well as an upper bound on the number of such access structures.

On the Composition of Matroids and Ideal Secret Sharing Schemes

Aspects of the security services in the CCITT draft 1988 X.400 recommendations for message handling systems are examined. A brief introduction to relevant cryptographic concepts is followed by a description of how some of the security services can be provided. Key management, as defined within the CCITT draft X.500 recommendations for directory services, and as referenced by the X.400 recommendations, is also described. A discussion of certain limitations of the current X.400 security architecture is included. >

CCITT/ISO standards for secure message handling

Later this year we shall see the release of the Third Generation Partnership Project (3GPP) specifications for WCDMA - the first third generation standard for mobile communications. This 3G system combines elements of both a radical departure and a timid evolution from the 2G system known as GSM. It is radically different from GSM in having a wide-band CDMA system for its air-interface, but it hangs on to the GSM/GPRS core switching network with its MAP based signalling system. In this paper we consider the security features in WCDMA, taking a critical look at where they depart from those in GSM, where they are still very much the same and how they may develop as the core switching network is replaced by an IP based infrastructure.
