10 Difference Between RSA Algorithm And DSA

SHARE

RSA Algorithm

  • RSA is a type of cryptosystem algorithm.
  • RSA algorithm works on the basis of the mathematical fact that it is not easy to factor the product of two prime numbers.
  • RSA algorithm came into existence in 1977.
  • RSA was developed by Leonard Aldeman, Aldi Shamir and Ron Rivest.
  • The process of key generation is slower in RSA.
  • RSA works best in the cases of encryption and verification.
  • RSA algorithm can be used in securing the transmission of data.
  • It is faster than DSA in encryption.
  • It is slower in decryption.

DSA

  • DSA is a type digital signature algorithm.
  • The DSA works on the mathematical concept of discrete algorithms and modular exponentiation.
  • The DSA Algorithm came into existence in the year 1991.
  • The DSA was developed by NIST (National institute of standards and technology).
  • The process of key generation is faster in DSA.
  • DSA works best in the cases of signing (digital) and decryption.
  • DSA algorithm can be used for digital signatures and their verification.
  • It is slower in encryption.
  • It is faster in decryption.
