SA ALGORITHM
RSA Algorithm is a Public key algorithm invented
in 1977 by Ron Rivest, Adi Shamir and Leonard
Adleman (RSA). It supports encryption and Digital
Signatures. It is the most widely used public key
algorithm which gets its security from integer
factorization Problem. It is relatively easy to
understand and implement. RSA computation occurs
with integers modulo n = p*q. It requires keys of at
least 1024 bits for good security. Keys of size 2048
bit provide best security. Widely used for secure
communication
Channel and for authentication to identity service
provider. RSA algorithm is used to encrypt the data
to provide security so that only the concerned user can
access it. The diagram below shows how to generate a
public and a private key.
