Summary :

The differential cryptanalysis method developed by E. Biham et al. presented a new index of cryptographic strength, i.e. signal to noise ratio (S/N). Their paper estimates S/N only for DES-like functions, i.e., cryptographic function based on iterating the same weak function n times. Other types such as including both stronger and weaker functions have not yet been examined. This paper examines the N-stage MULTI2 cipher algorithm to calculate S/N and shows there are many fast cipher algorithms having small S/N property.
