“…The mobile communication system needs wireless channels to establish secure communication and perform any transactions(G. Rajesh et al, 2018). In this scenario, error correction and secure transmission needs concentration in wireless channels that can be achieved through coding algorithms and ciphering algorithms respectively (Ktari et al, 2017;Martiri & Baxhaku, 2012;Park & Ogunfunmi, 2017;You & Sang, 2010). Presently, GSM uses coding and ciphering for mobile communication systems.…”

Mobile communication systems employ an encoding-encryption model to ensure secure data transmission over the network. This model encodes the data and encrypts it before transmitting it to the receiver's end. A non-trivial operation is performed to generate a strong secret key through which the data is encrypted. To support the security level of this model, arithmetic encoding is performed upon the data before encryption. The encrypted data is hashed using a lightweight hashing algorithm to generate a small and fixed length hash digest to overcome the overheads before it is communicated to the other end. To authorize the message being sent by the sender to the receiver, signature plays an important role. To avoid forging using proxy signature, blind signature, etc., a hybrid scheme is proposed in this article. The mobile communication system is enhanced by introducing the hybrid encode-encrypt-hashing mechanism which stands secure against the plain text attacks, mathematical attacks, and increases confidentiality of the data, security of the key, and thereby enhances the security of the system. In this paper, the design is applied over the mobile payment system which is considered as one of the appreciable mobile services. It proves that the designed security model can ensure swift transactions in a secure way.

An original wireless video transmission scheme called SoftCast has been recently proposed to deal with the issues encountered in conventional wireless video broadcasting systems such as cliff effect. In this paper, we first review the SoftCast scheme. We then analyze and compare two simple preprocessing methods that help to increase the quality at the receiver side. Each method consists of the subtraction of either the 8-bit mean gray level 128 or the mean value of all pixels for each video frame. Preprocessing methods are compared and evaluated under different channel signal-to-noise ratios using two metrics: Peak Signal-to-Noise Ratio (PSNR) and Structural SIMilarity (SSIM). Simulation results clearly highlight the importance of the preprocessing block in a SoftCast wireless video transmission scheme. Depending on the video input characteristics, an improvement of the PSNR score up to 2.1dB and 2.5dB can be observed for the average gray level method and for the mean frame method, respectively.
