What does RSA stand for in cryptographic protocols?

RSA stands for Rivest, Shamir, and Adleman, which are the last names of the three cryptographers who developed this widely used public key cryptographic protocol in 1977. RSA is significant because it enables secure data transmission over insecure channels. It works on the principles of key pair generation: a public key for encryption and a private key for decryption, making it foundational for online security and digital signatures.

The other choices reference terms that are not linked to RSA. The "Root Secure Algorithm," "Random Secure Access," and "Resilient Secure Algorithm" do not relate to any established cryptographic protocols or algorithms within the field of cybersecurity. Such terminology does not represent known systems or methods for securing data. Thus, recognizing RSA as Rivest, Shamir, and Adleman provides clarity on its historical and functional significance in creating secure communication in the digital realm.
