Cryptography with matrices

WebApr 8, 2024 · Matrix operations such as translation, rotation and sealing are used in graphics. Use of Matrices in Cryptography Cryptography is the technique to encrypt data so that only the relevant person can get the data and relate information. In earlier days, video signals were not used to encrypt. WebHere is the sketch of the method: 1) Alice constructs a matrix M; consists of m rows and n columns, where m and n are large numbers and very close in the number of digits. Say (1000 x 995). The matrix entries are complex numbers. 2) Alice uses SVD to decompose M yields M = U S V T, where S is the matrix with complex eigen values.

Teacher 2 = Using the decoding matrix and encoded message matrix find the decoded matrix. WebApr 15, 2024 · Laconic cryptography [17, 20, 22, 40] is an emerging paradigm to securely compute on large amounts of data in just two messages, while incurring very small communication.Specifically, in the laconic setting the receiver Alice has an input of very large size, whereas we typically think of the sender Bob’s input as smaller in size. WebFirst, compute the determinant of the matrix, detA. If detA is coprime to p, then you can be sure that A is invertible modp. Find the inverse of detA modulo p. This matrix we denote by (detA) −1 and will be the unique integer between 0 and p which satisfie (detA) × (detA) −1 ≡ 1 mod p. Next, compute the matrix of cofactors of A, call this B. dr naveau.be
