"Unlocking Secrets: A Journey through Asymmetric Key Cryptography – Past, Present, and Future"5/1/2024 Asymmetric Key Cryptography – Introduction, History, and Outline:Introduction:Asymmetric Key Cryptography, also known as Public Key Cryptography, is a cryptographic system that uses a pair of keys – a public key and a private key – to secure communication. Unlike symmetric key cryptography, where the same key is used for both encryption and decryption, asymmetric key cryptography uses two different keys for these processes.
History:The concept of asymmetric key cryptography was first introduced by Whitfield Diffie and Martin Hellman in 1976. They proposed the idea of public-key cryptography, which laid the foundation for secure communication without the need for a shared secret key. Later, Ronald Rivest, Adi Shamir, and Leonard Adleman developed the RSA algorithm, one of the most widely used asymmetric key algorithms. Outline:
