Supporting Transparent Caching with Standard Proxy Caches

by Ariel Cohen, Sampath Rangarajan, Navjot Singh - In Proceedings of the 4th International Web Caching Workshop , 1999
"... This paper presents the design and implementation of a network-level support mechanism that enables transparent proxy caching of web objects using standard non-transparent proxy caches. There are commercial caching products available for transparent proxy caching [1, 2, 3, 4]. These solutions requir ..."

Tor: The secondgeneration onion router,”

by Roger Dingledine - in 13th USENIX Security Symposium. Usenix, , 2004
"... Abstract We present Tor, a circuit-based low-latency anonymous communication service. This second-generation Onion Routing system addresses limitations in the original design by adding perfect forward secrecy, congestion control, directory servers, integrity checking, configurable exit policies, an ..."

;protocol cleaning" from anonymity: Onion Routing originally required a separate "application proxy" for each supported application protocol-most of which were never written, so many applications were never supported. Tor uses the standard and near-ubiquitous SOCKS [32] proxy interface, allowing us

"... ABSTRACT Using dealer's quotes and transactions prices on straight industrial bonds, we investigate the determinants of credit spread changes. Variables that should in theory determine credit spread changes have rather limited explanatory power. Further, the residuals from this regression are ..."

changes are principally driven by local supply/demand shocks that are independent of both credit-risk factors and standard proxies for liquidity. * Collin-Dufresne is at Carnegie Mellon University.

An Online Credential Repository for the Grid: MyProxy

by Jason Novotny - Proceedings of the Tenth International Symposium on High Performance Distributed Computing (HPDC-10), IEEE , 2001
"... Grid Portals, based on standard Web technologies, are increasingly used to provide user interfaces for Computational and Data Grids. However, such Grid Portals do not integrate cleanly with existing Grid security systems such as the Grid Security Infrastructure (GSI), due to lack of delegation capab ..."

capabilities in Web security mechanisms. We solve this problem using an online credentials repository system, called MyProxy. MyProxy allows Grid Portals to use the GSI to interact with Grid resources in a standard, secure manner. We examine the requirements of Grid Portals, give an overview of the GSI

Identity-based proxy re-encryption

by Matthew Green - In ACNS ’07 , 2007
"... In a proxy re-encryption scheme a semi-trusted proxy converts a ciphertext for Alice into a ciphertext for Bob without seeing the underlying plaintext. A number of solutions have been proposed in the public-key setting. In this paper, we address the problem of Identity-Based proxy re-encryption, whe ..."

Chosen-Ciphertext Secure Proxy Re-Encryption

by Ran Canetti, Susan Hohenberger - In Proc. of ACM-CCS’007 , 2007
"... In a proxy re-encryption (PRE) scheme, a proxy is given special information that allows it to translate a ciphertext under one key into a ciphertext of the same message under a different key. The proxy cannot, however, learn anything about the messages encrypted under either key. PRE schemes have ma ..."

Another Efficient Proxy Signature Scheme in the Standard Model

by Jianhong Zhang, Jane Mao - Journal of Information Science Engineering
"... Abstract. As an important delegation technology, Proxy signature al-lows an original signer to delegate her signing capability to a proxy signer and the proxy signer can produce a signature on behalf of the original signer. At present, the length of proxy signature is a sum of lengths of two signatu ..."

In this paper, we propose an efficient short proxy signature scheme without random oracle model based on Zhang et al.’s signature scheme. And the scheme is proven secure in the stan-dard model and the security

Anonymous proxy signatures

by Georg Fuchsbauer, David Pointcheval - SCN ’08, LNCS 5229 , 2008
"... Abstract We define a general model for consecutive delegations of signing rights with the following properties: The delegatee actually signing and all intermediate delegators remain anonymous. As for group signatures, in case of misuse, a special authority can open signatures to reveal the chain of ..."

We give formal definitions of security and show them to be satisfiable by constructing an instantiation proven secure under general assumptions in the standard
