  The Role of Cryptography in Secure Online Transactions Cryptography plays a vital role in securing online transactions by protecting sensitive data and ensuring the integrity and authenticity of transactions. Here's how cryptography contributes to secure online transactions: Secure Data Transmission 1. *Encryption*: Cryptography encrypts data in transit, making it unreadable to unauthorized parties. 2. *Secure Sockets Layer/Transport Layer Security (SSL/TLS)*: SSL/TLS protocols use cryptography to establish secure connections between clients and servers. Authentication and Verification 1. *Digital Signatures*: Cryptography-based digital signatures authenticate the sender's identity and ensure the integrity of transactions. 2. *Certificates*: Digital certificates, issued by trusted Certificate Authorities (CAs), verify the identity of parties involved in transactions. Data Integrity 1. *Hash Functions*: Cryptography-based hash functions ensure data integrity by detecting any t...

Emerging technologies like  blockchain , IoT, and artificial intelligence are transforming the way we live and work. Cryptography plays a vital role in securing these technologies and ensuring the integrity, confidentiality, and authenticity of data. Blockchain and Cryptography Blockchain technology relies heavily on cryptography to secure transactions and control the creation of new units. Cryptographic techniques like public-key cryptography and hash functions are used to: 1. *Secure transactions*: Cryptography ensures that transactions are tamper-proof and can be verified by nodes on the network. 2. *Control supply*: Cryptography is used to control the creation of new units, preventing unauthorized parties from manipulating the supply. IoT and Cryptography The Internet of Things (IoT) is a network of interconnected devices that collect and exchange data. Cryptography is essential for securing IoT devices and protecting sensitive data. Cryptographic techniques like encryption and...
