Changeable Order Management

The environment of small and medium-sized enterprises (SMEs) in Germany is characterized by constantly changing boundary conditions. To cope with these external influences, these enterprises have to adapt their internal organization structures and processes permanently. However, necessary changes often cannot be realized due to the rigidity of today’s order management information systems (OMS)....

One-Way Hash Functions With Changeable Parameters

In this paper, four new algorithms for improvements of MD5 and SHA-Keyed/Unkeyed MD5 and Keyed/Unkeyed SHA are proposed. We change the mode of ®xed retrieval of the parameters to that of dynamic retrieval of the parameters by applying a mapping between the index phrase and the parameter table. As shown in the experimental result, with 1% degradation of performance, comparing to the original alg...

Threshold changeable secret sharing schemes revisited

This paper studies the methods for changing thresholds in the absence of secure channels after the setup of threshold secret sharing schemes. First, we construct a perfect (t, n) threshold scheme that is threshold changeable to t ′ > t , which is optimal with respect to the share size. This improves the scheme of Wang and Wong by relaxing the requirement from q ≥ n + v to q > n with the secret-...

A Scale-Changeable Image Analysis Method

The biological vision system is far more efficient than machine vision system. This is due to the former has rich neural layers for representation and process. In order to obtain a non-task-dependent image representation schema, the early phase of neural vision mechanism is worth simulating. We design a neural model to simulate non-classical receptive field of ganglion cell and its local feedba...
