2 days ago · The secure computation of symmetric encryption schemes using Yao’s garbled circuits, such as AES, allows two parties, where one holds a plaintext block m and the other holds a key k, to compute Enc(k,m) without leaking m and k to one another. Due to its wide application prospects, secure AES computation has received much attention. However, the evaluation of AES circuits using Yao’s ...
4 days ago · Secure Hash Algorithms, also known as SHA, are a family of cryptographic functions designed to keep data secured. It works by transforming the data using a hash function: an algorithm that consists of bitwise operations, modular additions, and compression functions.
2 days ago · An Enigma machine is a famous encryption machine used by the Germans during WWII to transmit coded messages. An Enigma machine allows for billions and billions of ways to encode a message, making it incredibly difficult for other nations to crack German codes during the war — for a time the code seemed unbreakable.
1 day ago · Cryptography is a science for the development of cryptosystems and, along with cryptanalysis, a subfield of cryptology. With the help of cryptographic procedures such as encryption, data should be protected from unauthorized access and exchanged securely.
3 days ago · Decrypting enciphered messages involves three stages, defined somewhat differently in that era than in modern cryptography. First, there is the identification of the system in use, in this case Enigma; second, breaking the system by establishing exactly how encryption takes place, and third, solving , which involves finding the way that the ...
