The characterization of combinatorial or geometric structures in terms of their groups of automorphisms has attracted considerable interest in the last decades and is now commonly viewed as a natural generalization of Felix Klein s Erlangen program(1872).Inaddition, especiallyfor?nitestructures, importantapplications to practical topics such as design theory, coding theory and cryptography have made the ?eld even more attractive. The subject matter of this research monograph is the study and class- cation of ?ag-transitive Steiner designs, that is, combinatorial t-(v, k,1) designs which admit...

Authenticity and secrecy are two crucial concepts in cryptography and information security. Although independent in their nature, certain applications require that both aspects hold simultaneously. In the case of unconditional, or information-theoretic, security, authentication and secrecy codes can be used to maximise the likelihood of detecting deception. The construction of such codes is of great importance and has been considered by many researchers over the last few decades. Combinatorial Designs for Authentication and Secrecy Codes describes in depth classical and current...
