Various paradigms, attacker capabilities, and the relationships between them will be explored. The discussion will center around two key attack scenarios: CPA (Chosen-Plaintext Attack) and CCA (Chosen-Ciphertext Attack). An exploration of these scenarios will provide insights into the vulnerabilities that cryptosystems aim to mitigate. Additionally, the presentation will draw a comparison between the traditional public-key hybrid construction and the more contemporary Key Encapsulation Mechanism (KEM) paradigm. Furthermore, the talk will show how to achieve CCA security in a KEM by initially establishing CPA security.<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Speaker: Roberto Civino, PhD (DISIM Dept.
