What is the full meaning of RSA?

RSA: Rivest, Shamir, Adleman

RSA: RSA is for Rivest Shamir, Adleman. They are the inventors and maintainers of public-key encryption technology. It is a public key cryptosystem for secure data transmission. It is used for sensitive data transmission, particularly when data is transferred over the Internet.

This public key encryption technology developed by RSA Data Security Inc. Encrypting a message means that code is added to the message which converts it into a random mess. The RSA algorithm is based on the difficulty involved in the factorization of large numbers. The RSA algorithm is based on the fact that there is no efficient way to factor very large numbers. So, deducing an RSA key would take a huge amount of time and processing power.

The RSA algorithm is an asymmetric cryptography algorithm because it uses two different keys: a public key and a private key. The public key is accessible to everyone while the private key remains secret. Two numbers are part of the public key. One of them is a multiplication from two large prime numbers.

Additionally, the private key is also generated from the same prime numbers. Therefore, the private key cannot be compromised unless the large numbers are factored into the equation. This is difficult. The strength of encryption is dependent on key size. Large keys are more secure. RSA keys may be either 1024 bits or 2048 bits in length.

You can take, for instance:If you are able to share the code beforehand with your friend, you can either send an encrypted message to one another at any time. However, only you and your friend can see this message. What if the code is not available to you?

This scheme is also known by asymmetric encryption. It was designed to solve the problem of cryptography. This technology was designed to solve the greatest problem in cryptography, how do you send a coded message without having to share the code?

RSA encryption encrypts a message with a code, called a “public key”, which is not required to be hidden. According to the mathematical properties of RSA encryption, once a message with the public key has been encrypted, it can only then be decrypted using a different key called the private key. These messages can only be read by a pair, public and private, of keys.

RSA means Rivest, Shamir, Adleman. These three men are the originators of the popular RSA Algorithm. The RSA algorithm uses public-key encryption technology, which is a reliable cryptosystem for data transmission. Because of its traditional encryption method, this technology allows for the safe transmission of sensitive and private data over the internet.

RSA History

It was created by researchers Rivest, Shamir and Adleman from RSA Data Security Inc. In order to increase security, they added a code to this algorithm.

Properties of RSA

  • RSA is a public key encryption method.
  • This algorithm is secure and reliable for data transfer across the internet.
  • It protects the privacy of your data.
  • RSA is a rare type of security because it’s very difficult to break into keys via interceptors.

The Advantages of RSA

  • Implementing the RSA algorithm is easy.
  • RSA is a reliable and safe mechanism, so there is no risk of sending private data.
  • The RSA algorithm is a complex one because it requires difficult math.
  • It is easy to give public keys to others.

Disadvantages of RSA

  • Sometimes it can fail because we need both asymmetrical and symmetric encryption for complete encryption. RSA prefers symmetric encryption.
  • Because of the large number of participants, data shift is slow.
  • Sometimes it is necessary to verify the authenticity of public key documents with a third party.
  • For decryption, it is necessary that the receiver has powerful processing.

Working With RSA

It operates on two key points:

  • Public key:It contains two numbers. One number is the product of two prime numbers. This key is provided to all users.
  • Private keyThe public key contains 2 prime numbers. This key remains private.


The RSA Conference, an international conference series about IT security, is held in the United States, Europe and Asia/Japan. The RSA Conference is an international conference series on IT security that takes place in the United States, Europe, Asia/Japan, and the United Arab Emirates.

The U.S. conference of 2017 featured 15 keynotes, 700 speakers and 500 sessions. There were also 550 exhibitors.

The RSA conference is highly competitive with thousands of applicants for a handful of hundred speaking positions.

RSA Conference Awards

Annual awards are given out by the RSA conference to recognize individuals and organizations that excel in the following areas.
