The subject of the information technology system ( ITS ) of the important issues And contemporary thought in management, and various types of organizations seeking to apply and try to Access to the system of integrated information technology in order to continue growth and , And for compet this there is a need to study in the Iraqi organizations. The reseach aim to findout Level of performance (ITS) in two colleges from the University of Diyala, ( college of Science, and asmaay college of Education) and whether performance is consistent with the requirements of (ITS) integrated.
Selected sample of the Teams career in Tow colleges and at different levels The questionnaire form used to collect data , it was recovered from (67) For both colleges, and after research found the analysis to non-arrival of the colleges to the requirements of Integrated Information System technology , as well as the existence of significant differences between the colleges In the level of responses and the current performance level of the colleges
The growing use of tele
This paper presents a new secret diffusion scheme called Round Key Permutation (RKP) based on the nonlinear, dynamic and pseudorandom permutation for encrypting images by block, since images are considered particular data because of their size and their information, which are two-dimensional nature and characterized by high redundancy and strong correlation. Firstly, the permutation table is calculated according to the master key and sub-keys. Secondly, scrambling pixels for each block to be encrypted will be done according the permutation table. Thereafter the AES encryption algorithm is used in the proposed cryptosystem by replacing the linear permutation of ShiftRows step with the nonlinear and secret pe
