On the Clark-Jacob Version of SPLICE/AS

چکیده

SPLICE/AS is an authentication system for large-scale distributed systems. Two distinct aws have been discovered in SPLICE/AS|the most recent by Clark and Jacob. In addition to pointing out the aw, Clark and Jacob propose a modiication. We show the Clark-Jacob version is still awed by describing an attack that can be carried out under certain assumptions. We argue that the underlying reason for the aw is that the Clark-Jacob version and its predecessors are not using the appropriate cryptographic tool (namely a digital signature) for authentication. We also propose a new protocol. 1 Background Yamaguchi, et al. describe an authentication mechanism for large-scale distributed systems called SPLICE/AS 7]. Central to their design is a protocol for distributing public keys and authenticating principals (viz, clients and servers). The protocol Supported by grant HKUST 608/94E from the Hong Kong Research Grants Council.

Introduction: Leukemia is a heterogeneous malignant disease in which progression at the level of CD34+ cells has a major impact in drug resistance and relapse. The multi-drug resistance gene product, P-glycoprotein is an inhibitor of apoptosis proteins (IAPs), such as Survivin that are expressed simultaneously with several putative drug resistance parameters in CD34+ leukemia cells. In fact, IA...

Identification of a Novel Splice Site Mutation in RUNX2 Gene in a Family with Rare Autosomal Dominant Cleidocranial Dysplasia

Introduction: Pathogenic variants of RUNX2, a gene that encodes an osteoblast-specific transcription factor, have been shown as the cause of CCD, which is a rare hereditary skeletal and dental disorder with dominant mode of inheritance and a broad range of clinical variability. Due to the relative lack of clinical complications resulting in CCD, the medical diagnosis of this disorder is challen...

Fragility Curves for Reinforced Concrete Frames with Lap-Spliced Columns

Placing column lap-splice in the locations of possible nonlinear deformation may adversely affect the structures response to strong ground motions. Localization of damage in splice zone may change the structural response and prevent the load redistribution and development of a uniform pattern of nonlinear excursions among the various members. Validated by existing laboratory experiments, this s...
