A New approach in One Time Pad key management

Research Article of Research Journal of Mathematics and Computer Science A New approach in One Time Pad key management Gilda R. Bansimba, Regis F. Babindamana, Peter A. G. Kidoudou Université Marien Ngouabi, Faculté des Sciences et Techniques, BP: 69, Brazzaville, Congo Let (P,C,K,ε_k,D_k) be the One Time Pad cryptosystem. We consider P=C=K. In this paper, we improve the key management with introduction of the concept of mathematical key footprint to ensure the uniqueness of every generated key without storing it. We also combine the default operating system’s randomness Application Programming Interface (API) CSPRNG , with some further local system entropy parameters mainly the micro level of noise and environment brightness to enhance key generation randomness using any personal device. we introduce the use of negative keys to enlarge the key space K and give related algorithms.

An Algorithmic Random-Integer Generator based on the Distribution of Prime Numbers

Research Article of Research Journal of Mathematics and Computer Science An Algorithmic Random-Integer Generator based on the Distribution of Prime Numbers Bertrand Teguia Tabuguia Ph.D. student, Computer Algebra, Mathematics and Natural Sciences, University of Kassel, Germany, Heinrich-Plett-Str.40, 34132 Kassel We talk about random when it is not possible to determine a pattern on the observed out-comes. A computer follows a sequence of fixed instructions to give any of its output, hence the difficulty of choosing numbers randomly from algorithmic approaches. However, some algorithms like the Linear Congruential algorithm and the Lagged Fibonacci generator appear to produce “true” random sequences to anyone who does not know the secret initial input [1]. Up to now, we cannot rigorously answer the question on the randomness of prime numbers [2, page 1] and this highlights a connection between random number generator and the distribution of primes. From [3] and [4] one sees that it is quite naive to expect good random reproduction with prime numbers. We are, however, interested in the properties underlying the distribution of prime numbers, which emerge as sufficient or insufficient arguments to conclude a proof by contradiction which tends to show that prime numbers are not randomly distributed. To achieve this end, we use prime gap sequence variation. Our algorithm makes possible to deduce, in a binary choice case, a uniform behavior in the individual consecutive occurrence of primes, and no uniformity trait when the occurrences are taken collectively.

An Analysis of Cybercrime Awareness Amongst First Year Students in Nigerian Private University

Research Article of Research Journal of Mathematics and Computer Science An Analysis of Cybercrime Awareness Amongst First Year Students in Nigerian Private University Balogun O*, Hinmikaiye J, Adegbenle A.A, Oyebode A.A, Akinshola J, Nzenwata U.J Department of Computer Science, Babcock University, Nigeria The prevalence of Cybercrime the World over threatens to destroy the very fabric of peace. From financial fraud to theft identity, the ways in which this act continue to evolve and penetrate the most secure of digital entities calls for worry. A more disturbing trend is the perception of Nigerians being the purveyor of such acts. This study therefore seeks to find out what young Nigerians actually know about cybercrimes in order to gain an insight into what actually drives it and if possible, to discourage such acts from a tender age. Results show the perception of the World is not unfounded and recommendations that may go a long way in making this venture unattractive is highlighted.

Present panorama of the sequence of operators classes with their associated functional calculi , relevant in semigroup theory : the sequence of operators of halfplane , strip ,sector and parabola-type . It is shown that the basic results in the theory of C0-semigroup (the Hille-Yosida and the Trotter-kato theorem) follow easily from general functional calculus principles by Markus Haase [9] . The introduction of parabola-type sequence of operators allows to treat cosine the sequence of operators functions by functional calculus methods .
