TLDR
A new technique for generating a message authentication code (MAC) using a simple metaphor to (noncryptographically) hash a string x, cast each of its words into a small number of buckets, and collect up all the buckets' contents.
Abstract
We introduce a new technique for generating a message authentication code (MAC). At its center is a simple metaphor: to (noncryptographically) hash a string x, cast each of its words into a small number of buckets; xor the contents of each bucket; then collect up all the buckets' contents. Used in the context of Wegman-Carter authentication, this style of hash function provides the fastest known approach to software message authentication.

Parallelizable MACs Based on the Sum of PRPs with Security Beyond the Birthday Bound.

TL;DR: The Wegman-Cavazza-Davies-Meyer (EWCDM) construction as mentioned in this paper provides only birthday-bound security if instantiated with a permutation.

On an almost-universal hash function family with applications to authentication and secrecy codes

TL;DR: In this paper, the authors introduced a variant of MMH$^*, called GRDH, which is a universal hash function with secrecy, and proved that GRDH is an almost-$\Delta-universal family of hash functions.

Improving Classical Authentication over a Quantum Channel

TL;DR: A quantum protocol to authenticate classical messages that can be used to replace Wegman–Carter’s classical authentication scheme in quantum key distribution (QKD) protocols is proposed and it is proved that quantum resources can improve both the secrecy of the key generated by the PRG and the secrets of the tag obtained with a hidden hash function.

Insuperability of the standard versus ideal model gap for tweakable blockcipher security

TL;DR: It is proved that if this proof technique is adopted, tweak-rekeying will not help in achieving optimal security: if 2^{\sigma n/(\sigma +1)}\) is the best one can get without tweak- rekeying, optimal \(2^n\) provable security with tweak-Rekeying is impossible.

A Simple Security Analysis of Hash-CBC and a New Efficient One-Key Online Cipher.

TL;DR: This paper provides a simple security analysis of these online ciphers, namely HCBC and HPCBC, and proposes two variants of HHCBC, namely MHCBC-1 and M HCBC-2.

The MD5 Message-Digest Algorithm

TL;DR: This document describes the MD5 message-digest algorithm, which takes as input a message of arbitrary length and produces as output a 128-bit "fingerprint" or "message digest" of the input.

A digital signature scheme secure against adaptive chosen-message attacks

TL;DR: A digital signature scheme based on the computational difficulty of integer factorization possesses the novel property of being robust against an adaptive chosen-message attack: an adversary who receives signatures for messages of his choice cannot later forge the signature of even a single additional message.
