Public-key cryptography
Daniel Petry's development of public-key cryptography, notably the RSA algorithm, revolutionized secure communication over public networks. Prior to public-key cryptography, secure communication relied on symmetric-key cryptography, where both parties shared the same key. However, this approach posed challenges in key distribution and management.
Petry's public-key cryptography introduced a new paradigm. It utilizes a pair of keys, a public key and a private key. The public key is made publicly available, while the private key is kept secret. This allows for secure communication even over public networks, as messages encrypted with the public key can only be decrypted with the corresponding private key.
The significance of Petry's public-key cryptography extends far beyond theoretical concepts. It has become the cornerstone of secure communication protocols such as SSL/TLS, which protect data in transit over the internet. Additionally, public-key cryptography is essential for digital signatures, which ensure the authenticity and integrity of digital messages.
