These are commonly referred to as attacks against a cryptosystem. Cryptosystems are typically classiﬁed as being one of two types: private or public key. There are beneﬁts and drawbacks to each type of cryptosystem, and we will brieﬂy discuss each below. WebThe Rivest, Shamir, Adleman (RSA) cryptosystem is an example of a public key cryptosystem. RSA uses a public key to encrypt messages and decryption is performed using a corresponding private key. We can distribute our public keys, but for security reasons we should keep our private keys to ourselves. highest paid defensive lineman in history
