WebJun 15, 2024 · In this chapter we outline briefly why quantum computers can make RSA-type cryptosystems obsolete and how lattices can be used in cryptography. We concentrate on perhaps the best-known lattice system, NTRU, and explain how it is used and why attacks on it still seem computationally infeasible. Download chapter PDF.

To use matrices in encoding and decoding secret messages, our procedure is as follows. inches to 64thEach letter is represented by a number modulo 26. Though this is not an essential feature of the cipher, this simple scheme is often used: To encrypt a message, each block of n letters (considered as an n-component vector) is multiplied by an invertible n × n matrix, against modulus 26. To decrypt the message, each block is multiplied by the inverse of the matrix used for encryption. inches to 6 mmWeblinear algebra or elementary matrix theory.
