When was rsa encryption created

Learn more about the history of this cryptography system and its uses below! RSA is one of the first practical public-key cryptosystems and is widely used for secure data transmission. In such a cryptosystem, the encryption key is public and differs from the decryption key which is kept secret.

It introduced the radical idea of distributing cryptographic keys. It has become known as Diffie-Hellman-Merkle key exchange. Generally, a public encryption method relies on a public encryption algorithm, a public decryption algorithm, and a public encryption key. Using the public key and encryption algorithm, anyone can encrypt a message.

In other words, anyone could see the public encryption key to encrypt a message. But the actual decryption can happen by the means of the private key only, which is kept secret. But how does the RSA work then? Alice sends an encrypted message to Bob without any prior exchange of secret keys.

Common uses of the RSA algorithm range from hybrid encryption schemes and digital signatures. In the first case, it encrypts a symmetric key and sends it to a second party. RSA could also mark messages with a digital signature, and allowed originators to create messages intelligible only to intended recipients; third parties intercepting such transmissions would find them indecipherable.

Today, millions of copies of the RSA encryption and authentication technologies are installed worldwide. A native of Tel Aviv, Shamir earned his B. Shamir continues his work in cryptography and has received multiple honors, including the ACM Turing Award shared with Rivest and Adleman.

As Rivest and Shamir worked to develop an unbreakable key system, Adleman tried to break each one, doing so 42 times before the trio achieved success. Unlike previous methods requiring securely-exchanged keys to encrypt and decrypt messages, RSA provided a method for encryption and decryption without both parties needing a shared secret key.

RSA could also mark messages with a digital signature, and allowed originators to create messages intelligible only to intended recipients; third parties intercepting such transmissions would find them indecipherable.
