David Chaum
David Lee Chaum (born 1955) is an American computer scientist, List of cryptographers, cryptographer, and inventor. He is known as a pioneer in cryptography and privacy-preserving technologies, and widely recognized as the inventor of Digital currency, digital cash. His 1982 dissertation "Computer Systems Established, Maintained, and Trusted by Mutually Suspicious Groups" is the first known proposal for a blockchain protocol. Complete with the code to implement the protocol, Chaum's dissertation proposed all but one element of the blockchain later detailed in the Bitcoin White paper, whitepaper. He has been referred to as "the father of online anonymity", and "the godfather of cryptocurrency". He is also known for developing ecash, an electronic cash application that aims to preserve a user's anonymity, and inventing many cryptography, cryptographic protocols like the blind signature, mix networks and the Dining cryptographers protocol. In 1995 his company DigiCash created the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DigiCash
DigiCash Inc. was an electronic money corporation founded by David Chaum in 1989. DigiCash transactions were unique in that they were anonymous due to a number of cryptographic protocols developed by its founder. DigiCash declared bankruptcy in 1998 and subsequently sold its assets to eCash Technologies, another digital currency company, which was acquired by InfoSpace on February 19, 2002. History David Chaum is associated with the invention of Blind Signature Technology. In 1982, while studying at the University of California, Berkeley, Chaum wrote a paper describing the technological advancements to public and private key technology, in order to create this Blind Signature Technology. Chaum's Blind Signature Technology was designed to ensure the complete privacy of users who conduct online transactions. Chaum was concerned with the public nature and open access to online payments and personal information. He then proposed to construct a system of cryptographic protocols, in w ...

Cryptography
Cryptography, or cryptology (from "hidden, secret"; and ''graphein'', "to write", or ''-logy, -logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of Adversary (cryptography), adversarial behavior. More generally, cryptography is about constructing and analyzing Communication protocol, protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security (confidentiality, data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, Smart card#EMV, chip-based payment cards, digital currencies, password, computer passwords, and military communications. ...

Sherman Oaks, Los Angeles
Sherman Oaks (founded in 1927) is a neighborhood of the city of Los Angeles, California within the San Fernando Valley region. The neighborhood includes a portion of the Santa Monica Mountains, which gives Sherman Oaks a lower population density than some other areas in Los Angeles. History A partner of the Los Angeles Suburban Homes Company, Gen. Moses Hazeltine Sherman developed Sherman Oaks. The company had subdivided of land that would become Sherman Oaks. In 1927, each acre was sold for $780. Sherman's other major venture was the Los Angeles Pacific Railroad. In 1991, a group of homeowners living in the Chandler Estates area successfully petitioned former Los Angeles City Councilmember Zev Yaroslavsky to re-draw the boundaries of Sherman Oaks from Magnolia Boulevard to Burbank Boulevard in the north, and from Coldwater Canyon Avenue to Van Nuys Blvd in the west, with the goal of including their neighborhood. This request was nothing new to the San Fernando Valley; o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

RSA Award For Excellence In Mathematics
Formally called since 2025 The RSAC Conference Award for Excellence in Mathematics, is an annual award. It is announced at the annual RSA Conference in recognition of innovations and contributions in the field of cryptography. An award committee of experts, which is associated with the Cryptographer's Track committee at the RSA Conference (CT-RSA), nominates to the award persons who are pioneers in their field, and whose work has had applied or theoretical lasting value; the award is typically given for the lifetime achievements throughout the nominee's entire career. Nominees are often affiliated with universities or involved with research and development in the information technology industry. The award is cosponsored by the International Association for Cryptologic Research. While the field of modern cryptography started to be an active research area in the 1970s, it has already contributed heavily to Information technology and has served as a critical component in advancing ...

RSA Conference
The RSA Conference is a series of IT security conferences. Approximately 45,000 people attend one of the conferences each year. It was founded in 1991 as a small cryptography conference. RSA conferences take place in the United States, Europe, Asia, and the United Arab Emirates each year. The conference also hosts educational, professional networking, and awards programs. Since 2025 it was renamed The RSAC™ Conference, where the added “C” represents the new RSAC brand beyond the Conference – embracing Content, Connection, Culture & Conversation. It also represents Community as Cybersecurity is too big and complex to be solved alone. It requires a global community that shares knowledge, builds skills and is accessible to everyone. History Early history The name RSA (cryptosystem), RSA refers to the public-key encryption technology developed by RSA Data Security, Inc., which was founded in 1982.
