Notarized Federated Identity Management for Web Services

Abstract

Abstract. We propose a notarized federated identity management model that supports efficient user authentication when providers are unknown to each other. Our model introduces a notary service, owned by a trusted third-party, to dynamically notarize assertions generated by identity providers. An additional feature of our model is the avoidance of direct communications between identity providers and service providers, which provides improved privacy protection for users. We present an efficient implementation of our notarized federated identity management model based on the Secure Transaction Management System (STMS). We also give a practical solution for mitigating aspects of the identity theft problem and discuss its use in our notarized federated identity management model. The unique feature of our cryptographic solution is that it enables one to proactively prevent the leaking of secret identity information.

Finding MicroRNA Targets in Plants: Current Status and Perspectives

“…In this method, another short read alignment method, PatMaN [90] is employed to map degradome sequences. When searching for sRNA sequences that could potentially cleave a transcript accounting for the degradome peak at a given position, the authors perform a pre-defined rule-based complementarity search algorithm [87] , [91] , by traveling the 4-way tree [92] . sRNA−target interactions identified by PAREsnip will be further measured by a P -value based metric, and only high quality predictions will be retained.…”
