WebFeb 16, 2016 · In Section 3, the paper considers the multiple encryption problem and gives novel attacks that are better than what you would expect (for a general multiple encryption r times). For example, for 2DES there is an attack taking about 2 56 time and 2 56 space. You would therefore expect that 4DES would give you 2 112 time and 2 112 space. WebFeb 11, 2016 · RSA: any key size will do (starting with a ridiculously low minimum), but usually the key size should be a multiple of 8 bits and possibly of a specific size or higher (e.g. > 1024 bits); DH: the key size consists of two numbers, of which the size of the group is most important for security - specifying the key size is hard;
