A common approach to protect confidential information is to use a stream cipher which
combines plain text bits with a pseudo-random bit sequence. Among the existing stream …

In this thesis, I present two examples of fast-and-highly-parallel analog computation inspired
by architectures in biology. The first example, an RF cochlea, maps the partial differential …

The genomes of prokaryotes are dynamic and shuffling of gene order occurs frequently,
along with horizontal transfer of genes from external sources. Local conservation of gene …

Among the recent developments on stream ciphers, several indices on the security of stream
ciphers have been proposed for guaranteeing their strength. But the proposed indices are …
