Cryptography in Secure Transactions
In the financial and e-commerce sectors, cryptography secures transactions, ensuring data integrity and privacy.
-
Payment Systems:
- Credit card information and online transactions are encrypted using SSL/TLS.
- Tokenization is used to replace sensitive payment information with unique identifiers (tokens), reducing the risk of theft.
-
Cryptocurrency:
- Cryptocurrencies like Bitcoin rely on cryptographic algorithms, including elliptic curve cryptography and hash functions, to secure transactions and ensure the integrity of the blockchain.
- Digital wallets use private and public keys to manage and secure cryptocurrency assets.
-
Electronic Signatures:
- Digital signatures ensure the authenticity and integrity of electronic documents and transactions.
- Cryptographic algorithms like RSA or DSA (Digital Signature Algorithm) are used for signing and verifying digital signatures.
