    Operational Cost Factor Consideration of Path Management Method for MPLS Networks

    The recent improvements in broadband networks are enabling network carriers and providers to provide MultiProtocol Label Switching (MPLS) - based dedicated services for enterprise customers. These dedicated services will be widely introduced in interconnected networks to meet the demand of enterprise customers. Since end-to-end connection will be more complicated in...

    A Framework for Universally Composable Non-Committing Blind Signatures

    A Universally Composable (UC) blind signature functionality requires user to commit to the message to be blindly signed. It is thereby impossible to realize in the plain model. This paper shows that even non-committing variants of UC blind signature functionality cannot be realized in the plain model. The authors characterize...

    Authenticated Key Exchange and Key Encapsulation in the Standard Model

    In this paper, the authors introduce a new paradigm to realize various types of cryptographic primitives such as authenticated key exchange and key encapsulation in the standard model under three standard assumptions: the Decisional Diffie-Hellman (DDH) assumption, Target Collision Resistant (TCR) hash functions and Pseudo-Random Functions (PRFs). They propose the...
