John Black (cryptographer)
John Richard Black, Jr. is a cryptologist, programmer, and professor of computer science at the University of Colorado Boulder focusing on computer security. He graduated with a BA in computer science from CSU East Bay in 1988 and completed his PhD in cryptography at UC Davis with Phillip Rogaway in 2000. He has taught at CU-Boulder since 2002. Black has been involved in the invention of several cryptographic algorithms including UMAC, PMAC, OCB, and CMAC as well as algorithms related to Format Preserving Encryption. In 2004, he worked with students Martin Cochran and Ryan Gardner to defeat the security mechanisms of the Internet Chess Club The Internet Chess Club (ICC) is a commercial Internet chess server devoted to the play and discussion of chess and chess variants.

OCB Mode
Offset codebook mode (OCB mode) is an authenticated encryption mode of operation for cryptographic block ciphers. OCB mode was designed by Phillip Rogaway, who credits Mihir Bellare, John Black, and Ted Krovetz with assistance and comments on the designs. It is based on the '' integrity-aware parallelizeable mode'' (IAPM) of authenticated encryption by Charanjit S. Jutla. The ''OCB2'' version was proven insecure, while the original ''OCB1'' as well as ''OCB3'' from 2011 are still considered secure. Encryption and authentication OCB mode was designed to provide both message authentication and privacy. It is essentially a scheme for integrating a message authentication code (MAC) into the operation of a block cipher. In this way, OCB mode avoids the need to use two systems: a MAC for authentication and encryption for privacy. This results in lower computational cost compared to using separate encryption and authentication functions. There are three versions of OCB: OCB1, OCB2 a ...

Computer Security Academics
A computer is a machine that can be programmed to Execution (computing), carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as Computer program, programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the Computer hardware, hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of Programmable logic controller, industrial and Consumer electronics, consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devi ...

University Of California, Davis Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...

Internet Chess Club
The Internet Chess Club (ICC) is a commercial Internet chess server devoted to the play and discussion of chess and chess variants. ICC had over 30,000 subscribing members in 2005.John Black, Martin Cochran, Martin Ryan Gardner"Lessons Learned: A Security Analysis of the Internet Chess Club" acsac, pp.245–253, 21st Annual Computer Security Applications Conference (ACSAC'05), 2005. It was the first Internet chess server and was the largest pay to play chess server in 2005. History The first Internet chess server (ICS), programmed by Michael Moore and Richard Nash, was launched on 15 January 1992. Players logged in by telnet, and the board was displayed as ASCII text. Bugs in the server software allowed illegal moves, false checkmates etc. Over time more and more features were added to ICS, such as Elo ratings and a choice of graphical interfaces. The playing pool grew steadily, many of the server bugs were fixed, and players began to have higher expectations for stability. L ...

Format Preserving Encryption
In cryptography, format-preserving encryption (FPE), refers to encrypting in such a way that the output (the ciphertext) is in the same format as the input (the plaintext). The meaning of "format" varies. Typically only finite sets of characters are used; numeric, alphabetic or alphanumeric. For example: * Encrypting a 16-digit credit card number so that the ciphertext is another 16-digit number. * Encrypting an English word so that the ciphertext is another English word. * Encrypting an ''n''-bit number so that the ciphertext is another ''n''-bit number (this is the definition of an ''n''-bit block cipher). For such finite domains, and for the purposes of the discussion below, the cipher is equivalent to a permutation of ''N'' integers where ''N'' is the size of the domain. Motivation Restricted field lengths or formats One motivation for using FPE comes from the problems associated with integrating encryption into existing applications, with well-defined data models.

PMAC (cryptography)
PMAC, which stands for parallelizable MAC, is a message authentication code algorithm. It was created by Phillip Rogaway. PMAC is a method of taking a block cipher and creating an efficient message authentication code that is reducible in security to the underlying block cipher. PMAC is similar in functionality to the OMAC algorithm. Patents PMAC is no longer patented and can be used royalty-free. It was originally patented by Phillip Rogaway Phillip Rogaway is a professor of computer science at the University of California, Davis. He graduated from Beverly Hills High School, and later earned a BA in computer science from UC Berkeley and completed his PhD in cryptography at MIT, in t ..., but he has since abandoned his patent filings.

Programmer
A computer programmer, sometimes referred to as a software developer, a software engineer, a programmer or a coder, is a person who creates computer programs — often for larger computer software. A programmer is someone who writes/creates computer software or applications by providing a specific programming language to the computer. Most programmers have extensive computing and coding experience in many varieties of programming languages and platforms, such as Structured Query Language (SQL), Perl, Extensible Markup Language (XML), PHP, HTML, C, C++ and Java. A programmer's most often-used computer language (e.g., Assembly, C, C++, C#, JavaScript, Lisp, Python, Java, etc.) may be prefixed to the aforementioned terms. Some who work with web programming languages may also prefix their titles with ''web''. Terminology There is no industry-wide standard terminology, so "programmer" and "software engineer" might refer to the same role at different companies. Most typically, ...
