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 ...
Streaming multimedia data on the Internet is developing as a mainstream technology, which attracts many users by providing a new and convenient form of access to online multimedia information. While its strong business potential is obvious, many problems r ...
In this article we offer guidelines for the determination of key sizes for symmetric cryptosystems, RSA, and discrete logarithm-based cryptosystems both over finite fields and over groups of elliptic curves over prime fields. Our recommendations are based ...
In this paper, we address the problem of service availability in mobile ad-hoc WANs. We present a secure mechanism to stimulate end users to keep their devices turned on, to refrain from overloading the network, and to thwart tampering aimed at converting ...
Knapsack-based cryptosystems used to be popular in the beginning of public key cryptography before all but the Chor-Rivest cryptosystem (B. Chor and R.L. Rivest, 1985) was broken. The article demonstrates how to break this one with its suggested parameters ...
We describe recent advances in theories and architecture that support performance guarantees needed for quality of service networks. We start with deterministic computations and give applications to integrated services, differentiated services, and playbac ...
NOVELTY - Secret data is generated in one terminal or user equipment. Secret or hash value of secret is displayed on display terminal (11) or user equipment and is entered on input element of other terminal or user equipment. Shared secret data is used to ...
Method for performing electronic payments between a mobile equipment and a payment terminal over a short distance wireless interface, comprising displaying an identification (for example T; T-id) on the display (110) of said payment terminal (11), manually ...
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 ...
This paper describes improved methods for XTR key representation and parameter generation (Lenstra et al., 2000). If the field characteristic is properly chosen, the size of the XTR public key for signature applications can be reduced by a factor of three ...
