5. Cryptographic Research and NSA: Report of the Public Cryptography Study Group.

Author

Davida, George I.

Abstract

The Public Cryptography Study Group accepted the claim made by the National Security Agency that some information in some publications concerning cryptology could be inimical to national security, and is allowing the establishment of a voluntary mechanism, on an experimental basis, for NSA to review cryptology manuscripts.

15. A Crypto-Engine.

Author

Davida, George I. and Dancs, Frank B.

Abstract

In this paper we present a design for a crypto-engine. We shall discuss the design and show the instruction set of this coprocessor and then show how this could be used to implement most of the known encryption algorithms. We will discuss why a coprocessor approach may be a better solution than adoption of specific encryption algorithms which can be broken or decertified. [ABSTRACT FROM AUTHOR]

16. Arbitration in Tamper Proof Systems.

Author

Davida, George I. and Matt, Brian J.

Abstract

Given that tamperfree devices exist it is possible to construct true signature schemes that have the advantages of arbitrated signature schemes, protection against disavowing or forging messages, and lacking certain short commings. Other cryptographic protocols can also be improved. The contents of tamperfree devices cannot be examined as well as not modified. [ABSTRACT FROM AUTHOR]

18. Passports and Visas Versus IDs.

Abstract

Most of the proposed cryptographic based electronic IDS are not adequate when used in international identification protocols. In this paper we extend the concept of a cryptographic electronic ID to a system of electronic passports and visas that surpass existing paper versions. [ABSTRACT FROM AUTHOR]

19. O(log(n)) parallel time finite field inversion.

Author

Goos, G., Hartmanis, J., Barstow, D., Brauer, W., Brinch Hansen, P., Gries, D., Luckham, D., Moler, C., Pnueli, A., Seegmüller, G., Stoer, J., Wirth, N., Reif, John H., Litow, Bruce E., and Davida, George I.

Abstract

Let p be prime and assume that GF(pn) is given via an irreducible nth degree GF(p) polynomial. We exhibit a boolean circuit of size nO(1) and depth O(log(n)) such that for any x ε GF(pn) the circuit produces x−1. The circuit is based upon an interesting connection between finite field computations and the eigenvalues of certain matrices. The issue of circuit uniformity is also considered.

25. Database Security.

Davida, George I., Linton, David J., Szelag, C. Russell, and Wells, David L.

Subjects
*DATABASE security, *INFORMATION storage & retrieval systems, *COMPUTER security, *DATABASES, *COMPUTER files, *ELECTRONIC information resources, *DATA protection, *SECURITY systems, *SOFTWARE engineering
Abstract

Databases may be compromised by asking a set of queries which return only statistical information and making inferences about a specific entry from the results of the set of queries. We present methods of constructing the set of queries to compromise a database where all the queries in the set return the maximum of a set of k elements, or all queries return the mean of a set of k elements. In the case of the mean query, all elements involved will be compromised. We also consider bounds on the number of queries required to compromise the database. [ABSTRACT FROM AUTHOR]
