RSA Security LLC, formerly RSA Security, Inc. and doing business as RSA, is an American computer and network security company with a focus on encryption and encryption standards. RSA was named after the initials of its co-founders, Ron Rivest, Adi Shamir and Leonard Adleman, after whom the RSA public key cryptography algorithm was also named. Among its products is the SecurID authentication token. The BSAFE cryptography libraries were also initially owned by RSA. RSA is known for incorporating backdoors developed by the NSA in its products. It also organizes the annual RSA Conference, an information security conference.
Founded as an independent company in 1982, RSA Security was acquired by EMC Corporation in 2006 for US2.1billionandoperatedasadivisionwithinEMC.WhenEMCwasacquiredbyDellTechnologiesin2016,RSAbecamepartoftheDellTechnologiesfamilyofbrands.On10March2020,DellTechnologiesannouncedthattheywillbesellingRSASecuritytoaconsortium,ledbySymphonyTechnologyGroup(STG),OntarioTeachers’PensionPlanBoard(OntarioTeachers’)andAlpInvestPartners(AlpInvest)forUS2.1 billion, the same price when it was bought by EMC back in 2006.
RSA is based in Bedford, Massachusetts, with regional headquarters in Bracknell (UK) and Singapore, and numerous international offices.
Ron Rivest, Adi Shamir and Leonard Adleman, who developed the RSA encryption algorithm in 1977, founded RSA Data Security in 1982. The company acquired a "worldwide exclusive license" from the Massachusetts Institute of Technology to a patent on the RSA cryptosystem technology granted in 1983.
In 1994, RSA was against the Clipper chip during the Crypto War.
In 1995, RSA sent a handful of people across the hall to found Digital Certificates International, better known as VeriSign.
The company then called Security Dynamics acquired RSA Data Security in July 1996 and DynaSoft AB in 1997.
In January 1997, it proposed the first of the DES Challenges which led to the first public breaking of a message based on the Data Encryption Standard.

This course introduces the basics of cryptography. We review several types of cryptographic primitives, when it is safe to use them and how to select the appropriate security parameters. We detail how
Text, sound, and images are examples of information sources stored in our computers and/or communicated over the Internet. How do we measure, compress, and protect the informatin they contain?
L'objectif de ce cours est d'initier les étudiants à la pensée algorithmique, de les familiariser avec les fondamentaux de
l'informatique et des communications et de développer une première compétence
Cryptography, or cryptology (from κρυπτός "hidden, secret"; and γράφειν graphein, "to write", or -λογία -logia, "study", respectively), is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing 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.

The Clipper chip was a chipset that was developed and promoted by the United States National Security Agency (NSA) as an encryption device that secured "voice and data messages" with a built-in backdoor that was intended to "allow Federal, State, and local law enforcement officials the ability to decode intercepted voice and data transmissions." It was intended to be adopted by telecommunications companies for voice transmission. Introduced in 1993, it was entirely defunct by 1996.
