Large classes of weak keys have been found for the block cipher algorithm IDEA, previously known as IPES [2]. IDEA has a 128bit key and encrypts blocks of 64 bits. For a class of 2...
Differential cryptanalysis analyzes ciphers by studying the development of differences during encryption. Linear cryptanalysis is similar but is based on studying approximate linea...
This paper considers modern secret-key block ciphers. The theory behind the design and analysis of modern block ciphers is explained, and the most important known attacks are outli...
Today, many applications require users from one organization to access data belonging to organizations. While traditional solutions offered for the federated and mediated database...
We address the issue of encrypting data in local storage using a key that is derived from the user's password. The typical solution in use today is to derive the key from the...
