The Joint Photographic Experts Group (JPEG) has recently rolled out a new still image coding standard called JPEG 2000. This standard integrates an efficient image compression scheme along with functionalities required by multimedia applications, such as p ...
We propose a new approach to securing computer networks. With this approach, we achieve security in a fully self-organized manner; by this we mean that to secure a computer network, a security system does not require any kind of certification authority or ...
We present a practical selective forgery attack against RSA signatures with fixed-pattern padding shorter than two thirds of the modulus length. Our result extends the practical existential forgery of such RSA signatures (Brier et al., 2001). For an n-bit ...
Pseudorandomness is a classical model for the security of block ciphers. In this paper we propose convenient tools in order to study it in connection with the Shannon Theory, the Carter-Wegman universal hash functions paradigm, and the Luby-Rackoff approac ...
In 1984, C.H. Bennet and G. Brassard proposed a new protocol aimed to solve the problem of symmetric cryptographic key exchange. This protocol was called BB84 after the name of its authors. While a traditional method would rely on public key cryptography ( ...
We propose a new approach to securing self-organized mobile ad hoc networks. In this approach, security is achieved in a fully self-organized manner ...
It is the goal of our research work to elaborate on improvements to the software development methods so that quality attributes can be handled more systematically. By quality attributes we mean the large group of typically systemic properties of a software ...
The described method is used for generating a security document by applying a security pattern to an original image. The security pattern comprises a plurality of points, wherein each of said points represents a pattern value. Local averages are calculated ...
We use bounds of exponential sums to show that, for a wide class of parameters, the modification of the digital signature algorithm (DSA) scheme proposed by A.K. Lenstra (see Proc. Asiacrypt'96, Lect. Notes in Comp. Sci., vol.1163, p.57-64, 1996) is as sec ...
So far, research on mobile ad hoc networks has been focused primarily on routing issues. Security, on the other hand, has been given a lower priority. This paper provides an overview of security problems for mobile ad hoc networks, distinguishing the threa ...
