The security of RSA relies on the practical difficulty of factoring the product of two large prime numbers, the "factoring problem". Breaking RSA encryption is known as the RSA problem. Whether it is as difficult as the factoring problem is an open question. [3] There are no published methods to defeat the system if a large enough key is used.
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.
Later, the 128-bit RSA SecurID algorithm was published as part of an open source library. [4] In the RSA SecurID authentication scheme, the seed record is the secret key used to generate one-time passwords. Newer versions also feature a USB connector, which allows the token to be used as a smart card-like device for securely storing certificates.
In cryptography, the Full Domain Hash (FDH) is an RSA-based signature scheme that follows the hash-and-sign paradigm. It is provably secure (i.e., is existentially unforgeable under adaptive chosen-message attacks) in the random oracle model. FDH involves hashing a message using a function whose image size equals the size of the RSA modulus ...
Dell BSAFE, formerly known as RSA BSAFE, is a FIPS 140-2 validated cryptography library, available in both C and Java. BSAFE was initially created by RSA Security, which was purchased by EMC and then, in turn, by Dell. When Dell sold the RSA business to Symphony Technology Group in 2020, Dell elected to retain the BSAFE product line.
The PKCS#11 standard originated from RSA Security along with its other PKCS standards in 1994. In 2013, RSA contributed the latest draft revision of the standard (PKCS#11 2.30) to OASIS to continue the work on the standard within the newly created OASIS PKCS11 Technical Committee. [2] The following list contains significant revision information:
Rivest was a founder of RSA Data Security (now merged with Security Dynamics to form RSA Security), Verisign, and of Peppercoin. His former doctoral students include Avrim Blum , Benny Chor , Sally Goldman , Burt Kaliski , Anna Lysyanskaya , Ron Pinter , Robert Schapire , Alan Sherman , [ 1 ] and Mona Singh .
In the mid-1990s the NetWitness technology was established by CTX Corporation, a Washington D.C. based system integrator. The technology, initially chartered as a US Government research project, was created to help analysts better understand large volumes of captured network data for various types of investigations.
