Let $\Omega$ be a set of entities. An *access structure* $\mathcal{A}$ is a collection of nonempty subsets of the power set $P(\mathcal{A})$. This structure is called *monotone*, if $A\in\mathcal{A}$ …

An attack on TLS and related protocols as of may 2015. This attack uses pre-computations to attack short prime diffie hellmann key exchange, primes with up to 1024 bits length are considered broken. I…

routing protocols that create hard-to-trace communications by using a chain of proxy servers known as mixes which take in messages from multiple senders, shuffle them, and send them b…
× 3
a feature of some digital signature schemes, whereas some or all of the message signed is embedded in the signature, recovered as part of signature verification, and thus needs not…

a key derivation function ([tag:kdf]) that uses a key in the computation.

a Crypto SDK was developed by Microsoft to support experimentation with the foundational features of the U-Prove technology. It is made available under the Apache 2.0 open-source license, w…

Encryption of data represented in XML according to the W3C Specification.
× 2
a technology that allows telephone calls to be made over computer networks like the Internet.
