    Risk And The Role Of Collateral In Debt Renegotiation

    In his basic model of debt renegotiation, Bester [1994] argues that collateral is more effective if high risk projects are financed. This result, however, crucially depends on the definition of risk. Using the second-order stochastic dominance criterion introduced by Rothschild and Stiglitz [1970], the authors show that it is not...

    Constructing Optimal Authentication Codes With Perfect Multi-Fold Secrecy

    Authentication and secrecy are two crucial concepts in cryptography and information security. Although independent in their nature, various scenarios require that both aspects hold simultaneously. For information-theoretic or unconditional security (i.e. robustness against an attacker that has unlimited computational resources), authentication and secrecy codes have been investigated for quite some...
