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. WebMar 25, 2024 · Cryptography. In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption —a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code. In common parlance, “cipher” is synonymous ...

WebCRYPTOGRAPHY Encryption is the process of scrambling data within a communication system to make it unintelligible in such a way that the process can later be reversed by authorised people to reveal the original data by a data decryption process. WebThe inverse of matrix K for example is (1/det (K)) * adjoint (K), where det (K) <> 0. I assume that you don't understand how to calculate the 1/det (K) in modulo arithmetic and here is where linear congruences and GCD come to play. Your K has det (K) = -121. Lets say that the modulo m is 26.
