 UMAC -- Message Authentication Webpage
UMAC is a message authentication code : an algorithm for generating authentication tags, which are used to ensure the authenticity and integrity of transmitted messages.
UMAC is the fastest message authentication code that has been reported on in the cryptographic literature.
Small algorithmic changes were made in 2004 and a number of UMAC options were eliminated for simplicity.

  UMAC ATHLETE OF THE WEEK
Heise was 4-1 at the Midwest Region Invitational this past weekend, three of her wins coming against 7th ranked Washington (Mo.) University.
Heise led the Saints through a 6-2 mark in Texas over spring break with a 5-1 record and a save while on the mound and a.467 batting average at the plate.
After leading the Saints to a 4th place finish at the NAIA Regional Meet, and a berth in the NAIA National Championship race, Saints senior Jen Houck was named the Runner of the Week in the UMAC.

  ICOM Publications
The Spring 2002 issue of the journal Museologia, published by the Museu de Ciência of the University of Lisbon, is entirely devoted to the proceedings of the first UMAC conference, which was held in Barcelona in 2001.
The papers given at this meeting attempt to illustrate how diverse university museums are and what a wide range of disciplines they encompass, and to describe the difficulties they sometimes face.
Many university museums are not as well-known as they should be, and one of UMAC's aims is to raise their profile with governing bodies and the general public.

UMAC enjoys a rigorous security analysis and its only internal "cryptographic" component is a block cipher used to generate the pseudorandom pads and internal key material.
What this means is that an adversarial attack on UMAC that forges with probability significantly exceeding the established collision probability of UHASH will give rise to an attack of comparable complexity which breaks the block cipher, in the sense of distinguishing the block cipher from a family of random permutations.
When UMAC is used within a higher-level protocol there may already be a field, such as a sequence number, which can be co-opted so as to specify the nonce needed by UMAC [5].

 UMAC Baseball -- 1997 13 Year Old Maryland District III Babe Ruth Tournament
UMAC jumped to a 10-2 lead in the bottom of the 3rd after sending 12 batters to the plate and scoring 7 runs.
UMAC got on the board in the second when Jeff Villani reached on an error, advanced to 3rd on steals, Dan Stouffer walked and both runners advanced a base after a balk by the M.V. pitcher, scoring Villani.
At the end of three innings UMAC led 4-0 after several walks and a sac-fly by Stouffer, but it was in the bottom of the 5th that the real damage was done by UMAC's batters as they sent 8 batters to the plate and scored 5 more runs to take a 9-0 lead.

 I-D ACTION:draft-krovetz-umac-01.txt
UMAC was designed to provide strong authenticity guarantees while being flexible, provably secure, and **as fast as possible** on modern (and emerging) processors.
UMAC's security analysis is based on two factors: 1) The 20-year old methodology (due to Carter and Wegman) for building MAC functions on the basis of universal hashing.
In this sense, UMAC does not need to be subject to cryptanalytical scrutiny before it can be used; you just need to believe that the underlying block cipher is secure.

 BHHKKR00 - UMAC
UMAC is designed to be very fast to compute in software on contemporary uniprocessors.
To generate the authentication tag on a given message, a "universal" hash function is applied to the message and key to produce a short, fixed-length hash value, and this hash value is then xor'ed with a key-derived pseudorandom pad.
UMAC enjoys a rigorous security analysis and its only internal "cryptographic" component is a block cipher used to generate the pseudorandom pads and internal key material.

 RFC 4418 - UMAC: Message Authentication Code using Universal Hashing
UMAC Tag Generation Tag generation for UMAC proceeds by using UHASH (defined in the next section) to hash the message, applying the PDF to the nonce, and computing the xor of the resulting strings.
Breaking the MAC means that the attacker is able to generate, on its own, with no knowledge of the key K, a new message M (i.e., one not previously transmitted between the legitimate parties) and to compute on M a correct authentication tag under the key K. This is called a forgery.
Krovetz Informational [Page 18] RFC 4418 UMAC March 2006 Let us reemphasize: a forging probability of 1/2^60 does not mean that there is an attack that runs in 2^60 time; to the contrary, as long as the block cipher in use is not broken there is no such attack for UMAC.

 SoundClick artist: PIMP T - Renown for his live show, rap emcee Pimp Tea brings forth a diverse style, but with a ...
He's been nominated for ECMA and UMAC awards; performed on MusiquePlus & ZeD; and had a video featured on MuchMusic & MusiquePlus.
In the interim, a wacky Halloween costume earned him the nickname PIMP-T. However, it was his amusing multimedia project for a university course in 2000, which caused the name to stick.
Pimp Tea used these accolades as a springboard for the creativity, uniqueness and positivity infused throughout his 2002 debut album, Power Is Mindful Peace.

 Hedley Enterprises - UMAC-CORE
My opinion of UMAC is that I feel I have a little more energy and in general a feeling of uplift of spirit.
We're not sure if mom's health is due to the plankton or the tea, or a combination of both, but she is very much alive and regaining strength and motor skills every day, almost 5 weeks after she was given 2 - 3 days to live.
UMAC CORE has changed this for me. I now feel healthy, mentally and physically, and have energy to spare at the end of the day.

 UMAC - Heason Technologies Group
UMAC type boards are mounted inside 3U racks and the system is completed with a selection of power supplies and optional 3U servo amplifiers.
UMAC 3U racks are available in many different sizes, providing a CE compliant, rugged and integrated system, packaging the electronics, built-in breakout connectors, and power supply in an enclosed system.
However, because UMAC is based on the UBUS (Universal BUS), if a particular feature for the UMAC system is desired but not yet supported, Delta Tau provides all the necessary information for its development.

By submitting this Internet-Draft, each author represents that any applicable patent or other IPR claims of which he or she is aware have been or will be disclosed, and any of which he or she becomes aware will be disclosed, in accordance with Section 6 of BCP 79.
UMAC uses a keyed function, called UHASH (also specified in this document), as the keyed hash function H and uses a pseudorandom function F whose default implementation uses the AES algorithm.
What this means is that an adversarial attack on UMAC that forges with probability significantly exceeding the established collision probability of UHASH will give rise to an attack of comparable complexity which breaks the block cipher, in the sense of distinguishing the block cipher from a family of random permutations.

To achieve such speeds UMAC uses a variant of the Carter-Wegman paradigm, employing a new universal-hash-function, NH, as well as a new way to use such a family to construct a MAC.
The "cryptographic" work of UMAC is done using standard primitives of the user's choice, such as a block cipher or cryptographic hash function; no new heuristic primitives are developed here.
Instead, the security of UMAC is rigorously proven, in the sense of giving exact and quantitatively strong results which demonstrate an inability to forge UMAC-authenticated messages assuming an inability to break the underlying cryptographic primitive.

The Upper Midwest Athletic Conference (UMAC) began in 1972 as the Twin Rivers Conference and was renamed to its current title in the early 1980's.
Twelve schools have been a part of the UMAC conference over the past 30 years and the conference currently has 8 full members and 6 associate members in football.
Currently, the UMAC is in the process of becoming a National Collegiate Athletic Association (NCAA) Division III conference and is in the transition period.
