- lang: eng
text: Market transactions are subject to information asymmetry about the delivered
value proposition, causing transaction costs and adverse market effects among
buyers and sellers. Information systems research has investigated how review systems
can reduce information asymmetry in business-to-consumer markets. However, these
systems cannot be readily applied to business-to-business markets, are vulnerable
to manipulation, and suffer from conceptual weak spots since they use textual
data or star ratings. Building on design science research, we conceptualize a
new class of reputation systems based on monetary-based payments as quantitative
ratings for each transaction stored on a blockchain. Using cryptography, we show
that our system assures content confidentiality so that buyers can share and sell
their ratings selectively, establishing a reputation ecosystem. Our prescriptive
insights advance the design of reputation systems and offer new paths to understanding
the antecedents, dynamics, and consequences to reduce information asymmetry in
B2B transactions.

text: In this paper, we introduce updatable anonymous credential systems (UACS)
and use them to construct a new privacy-preserving incentive system. In a UACS,
a user holding a credential certifying some attributes can interact with the corresponding
issuer to update his attributes. During this, the issuer knows which update function
is run, but does not learn the user's previous attributes. Hence the update process
preserves anonymity of the user. One example for a class of update functions are
additive updates of integer attributes, where the issuer increments an unknown
integer attribute value v by some known value k. This kind of update is motivated
by an application of UACS to incentive systems. Users in an incentive system can
anonymously accumulate points, e.g. in a shop at checkout, and spend them later,
e.g. for a discount.

text: "We present CLARC (Cryptographic Library for Anonymous Reputation and Credentials),
an anonymous credentials system (ACS) combined with an anonymous reputation system.\r\n\r\nUsing
CLARC, users can receive attribute-based credentials from issuers. They can efficiently
prove that their credentials satisfy complex (access) policies in a privacy-preserving
way. This implements anonymous access control with complex policies.\r\n\r\nFurthermore,
CLARC is the first ACS that is combined with an anonymous reputation system where
users can anonymously rate services. A user who gets access to a service via a
credential, also anonymously receives a review token to rate the service. If a
user creates more than a single rating, this can be detected by anyone, preventing
users from spamming ratings to sway public opinion.\r\n\r\nTo evaluate feasibility
of our construction, we present an open-source prototype implementation."

text: "In this paper, we investigate the use of trusted execution environments (TEEs,
such as Intel's SGX) for an anonymous communication infrastructure over untrusted
networks.\r\nFor this, we present the general idea of exploiting trusted execution
environments for the purpose of anonymous communication, including a continuous-time
security framework that models strong anonymity guarantees in the presence of
an adversary that observes all network traffic and can adaptively corrupt a constant
fraction of participating nodes.\r\nIn our framework, a participating node can
generate a number of unlinkable pseudonyms. Messages are sent from and to pseudonyms,
allowing both senders and receivers of messages to remain anonymous. We introduce
a concrete construction, which shows viability of our TEE-based approach to anonymous
communication. The construction draws from techniques from cryptography and overlay
networks. \r\nOur techniques are very general and can be used as a basis for future
constructions with similar goals."

text: 'In this paper, we introduce the notion of delegatable attribute-based anonymous
credentials (DAAC). Such systems offer fine-grained anonymous access control and
they give the credential holder the ability to issue more restricted credentials
to other users. In our model, credentials are parameterized with attributes that
(1) express what the credential holder himself has been certified and (2) define
which attributes he may issue to others. Furthermore, we present a practical construction
of DAAC. For this construction, we deviate from the usual approach of embedding
a certificate chain in the credential. Instead, we introduce a novel approach
for which we identify a new primitive we call dynamically malleable signatures
(DMS) as the main ingredient. This primitive may be of independent interest. We
also give a first instantiation of DMS with efficient protocols. '
