Symbolic Universal Composability [PDF]
We introduce a variant of the Universal Composability framework (UC; Canetti, FOCS 2001) that uses symbolic cryptography. Two salient properties of the UC framework are secure composition and the possibility of easily defining security by giving an ideal

On the Composability of Statistically Secure Random Oblivious Transfer [PDF]
We show that random oblivious transfer protocols that are statistically secure according to a definition based on a list of information-theoretical properties are also statistically universally composable.

Randomized Oblivious Transfer for Secure Multiparty Computation in the Quantum Setting [PDF]
Secure computation is a powerful cryptographic tool that encompasses the evaluation of any multivariate function with arbitrary inputs from mutually distrusting parties.

SSH-DAuth: secret sharing based decentralized OAuth using decentralized identifier [PDF]
OAuth2.0 is a Single Sign-On approach that helps to authorize users to log into multiple applications without re-entering the credentials. Here, the OAuth service provider controls the central repository where data is stored, which may lead to third ...

Impossibility Results for Universal Composability in Public-Key Models and with Fixed Inputs [PDF]
Universal composability and concurrent general composition consider a setting where secure protocols are run concurrently with each other and with arbitrary other possibly insecure protocols.

Evaluating Security of Voting Schemes in the Universal Composability Framework [PDF]
Remark. Appears in ACNS 2004, this is the full paper. It contains a proof of Theorem 1, some more details on security against adaptive adversaries in the erasure-free model, and a conclusion.

iUC: Flexible Universal Composability Made Simple [PDF]
Proving the security of complex protocols is a crucial and very challenging task. A widely used approach for reasoning about such protocols in a modular way is universal composability.

Protection Against Subversion Corruptions via Reverse Firewalls in the Plain Universal Composability Framework [PDF]
While many modern cryptographic primitives have stood the test of time, attackers started to expand beyond classic cryptanalysis by targeting implementations.

Universal composable threshold signature
Threshold signature allowed any subset of t parties generating a signature,but that disallowed the creation of a valid signature if fewer than t parties participate in the protocol.Since the security of threshold signature was only con-sidered in a ...

The robust distributed ledger model for a multidimensional blockchain security analysis [PDF]
The paper considers the problem of constructing a model of the robust distributed ledger for security proof of a multidimensional blockchain. Several requirements for the model are imposed, among which most important are compatibility with existing ...
