In this work, we introduce a new method in cryptography. It is using the Moore-Penrose generalized inverse of a rectangular matrix to the cryptographic system. We use a rectangular matrix which has the Moore-Penrose generalized inverse as a key. We mean, the rectangular matrix which has full row rank, or the rectangular matrix which has full column rank, or the rectangular matrix which has full factorization.

Nanotechnology is the most emerging branch of science and technology leading to the development of devices starting from electronics to biomedical devices. It is thus desired that the students should have basic idea of this new emerging technology during their school education. Experimental demonstration of simple experiments of synthesizing nanomaterials and demonstration of its properties are very...

Over the years, the generally accepted fact is that the Sarrus’s rule which was developed by a French Mathematician, P. F. Sarrus in 1833, is only limited to finding the determinant of 3 × 3 Matrices. However, in my previous work [1] “On the Extension of Sarrus’ Rule to n × n (n > 3) Matrices: Development of New Method for the Computation of the Determinant of 4 × 4 Matrices” which was published...
