We present the first universally composable key-management functionality, formalized in the GNUC framework by Hofheinz and Shoup. It allows the enforcement of a wide range of security policies and can be extended by diverse key usage operations with no need to repeat the security proof. We illustrate its use by proving an implementation of a security token secure with respect to arbitrary key-u...

83.2 Key Management Myths .................................................... 1070 Myth 1: A Key Qualifies as “Randomly Generated” If One or More Persons Create the Key Components from Their Imagination † Myth 2: An “Authorized” Person Can Create or Enter Cryptographic Keys without Compromising a Key † Myth 3: Requiring a Second Person to Supervise or Observe the Key Entry Process Is Dual Cont...

Abstract A water demand management typology identifies three key WDM measures, namely: losses, economic instruments, and non-price mechanisms. The guidebook describes each of these measures provides case illustrations their effective implementation in different ASEAN cities.

Many cryptographic key exchange and management protocols involve computationally expensive operations, such as modular exponentia-tions, and are therefore vulnerable to resource clogging attacks. This paper overviews and discusses the basic principles and the rationale behind an anti-clogging mechanism that was originally designed and proposed to protect the Photuris Session Key Management Prot...
