In this paper, we present some new applications of the bounds for the differential probability of a SDS (Substitution-Diffusion-Substitution) structure by Park et al. at FSE 2003. Park et al. have applied their result on the AES cipher which uses the SDS structure based on MDS matrices. We shall apply their result to practical ciphers that use SDS structures based on {0, 1}-matrices of size n×n...

We investigate unconditional security for message authentication protocols that are designed using two-channel cryptography. (Two-channel cryptography employs a broadband, insecure wireless channel and an authenticated, narrow-band manual channel at the same time.) We study both noninteractive message authentication protocols (NIMAPs) and interactive message authentication protocols (IMAPs) in ...

background: increasing cost of cancer in the world and particularly in developing countries, postulates need for public participation in cancer control activities, including prevention, treatment and supportive care. we studied role of different factors on the success of advertising through short message services (sms) for public donations for cancer control activities. materials and methods: b...
