RSA Security LLC, [5] formerly RSA Security, Inc. and trade name RSA, is an American computer and network security company with a focus on encryption and decryption 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.
RSA (Rivest–Shamir–Adleman) is a public-key cryptosystem, one of the oldest widely used for secure data transmission. The initialism "RSA" comes from the surnames of Ron Rivest, Adi Shamir and Leonard Adleman, who publicly described the algorithm in 1977. An equivalent system was developed secretly in 1973 at Government Communications ...
The RSA SecurID authentication mechanism consists of a "token"—either hardware (e.g. a key fob) or software (a soft token)—which is assigned to a computer user and which creates an authentication code at fixed intervals (usually 60 seconds) using a built-in clock and the card's factory-encoded almost random key (known as the "seed").
Rohit Ghai is the CEO of RSA, a global leader in identity and access management (IAM) solutions for security-first organizations. Around the world, more than 9,000 organizations rely on RSA to ...
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 ...
For example, RSA relies on the assertion that factoring large numbers is hard. A weaker notion of security, defined by Aaron D. Wyner, established a now-flourishing area of research that is known as physical layer encryption. [4] It exploits the physical wireless channel for its security by communications, signal processing, and coding techniques.
