WebbThe RSA algorithm (Rivest-Shamir-Adleman) is the basis of a cryptosystem -- a suite of cryptographic algorithms that are used for specific security services or purposes -- which enables public key encryption and is widely used to secure sensitive data, particularly when it is being sent over an insecure network such as the internet. Webb28 jan. 2024 · One of the major algorithms used for data protection on the internet is the Rivest, Shamir, and Adleman (RSA algorithm), named after the inventors of this encryption and decryption algorithm. RSA is a public key algorithm widely used for secure data transmission. This is one of the major cyber security methods of data protection.
