Message classification is a text classification task that has provoked much interest in machine learning. One aspect of message classification that presents a particular challenge is the classification of short text messages. This paper presents an assessment of applying a casebased reasoning approach that was developed for long text messages (specifically spam filtering) to short text messages...

We study deterministic fault-tolerant gossiping protocols in directed Geometric Radio Networks (in short, directed GRN). Unpredictable node and link faults may happen during every time slot of the protocol’s execution. We first consider the single-message model where every node can send at most one message per time slot. We provide a protocol that, in any directed GRN G of n nodes, completes go...

Short message service (SMS) has been a very important tool in mobile communication for years, and the usage is still growing. The difficulty in editing messages on handset devices can be overcome by sending SMS messages through Internet-connected gateways. Furthermore, we can adopt such mechanisms to integrate mobile-computing ability to many existing information systems. However, it’s easy to ...

The radio determination service system (RDSS), a navigation and positioning independently developed by China, features services such as short-message communication, position reporting, international search rescue. L-band pseudo-range phase data are the primary sources in precise orbit (POD) for geostationary Earth (GEO) satellite BeiDou system, especially manoeuvre period. These only POD GEOs. ...

We propose a new (n, n) double block length hash function where collision and preimage security bound is respectively O ( 2 ) and O ( 2 ) . The strategic point of this scheme is able to handle short message tn (t < 1) bit, which is very significant issue for RFID tag security. It is known that the RFID tag needs to proceed short message but MDC-2, MDC-4, MJH are not properly suitable for meetin...

In this paper, we introduce the intermediate hashed Diffie-Hellman (IHDH) assumption which is weaker than the hashed DH (HDH) assumption (and thus the decisional DH assumption), and is stronger than the computational DH assumption. We then present two public key encryption schemes with short ciphertexts which are both chosen-ciphertext secure under this assumption. The short-message scheme has ...
