Software-modeling complex SCSPS stream encryption algorithm

An Algorithm for Fast Software Encryption

An algorithm for fast software encryption is proposed in this paper. It is based on the architecture of new pseudo random number generator (PRNG), named Self−Shrinking p–adic Generator (SSPG). In the paper first, the basic SSPG architecture and algorithm are recalled. Then, the software implementation in Visual C++ environment is presented. Finally, the results of some images and texts, encrypt...

Segmentation and Encryption of Satellite Images Using Stream Cipher Algorithm

Information security plays one of the very important roles in the field of emergent information and communication technology. The applications such as medical images and satellite images needs the security only in the required portion, which contains the useful information .To improve the perception of surroundings and to monitor the earth’s surface, remote sensing is used and it led the way fo...

An Efficient Stream Cipher Algorithm for Data Encryption

Nowadays the data telecommunication security has been provided by most of well-known stream cipher algorithms which are already implemented in different secure protocols such as GSM, SSL, TLS, WEP, Bluetooth etc. These algorithms are A5/1, A5/2, E0 and RC4. On the other hand, these public algorithms already faced to serious security weakness such that they do not provide enough security of prop...

Cryptanalysis of GSM encryption algorithm A5/1

The A5/1 algorithm is one of the most famous stream cipher algorithms used for over-the-air communication privacy in GSM. The purpose of this paper is to analyze several weaknesses of A5/1, including an improvement to an attack and investigation of the A5/1 state transition. Biham and Dunkelman proposed an attack on A5/1 with a time and data complexity of 239.91and 221.1, ...
