Data Security Measures
Encryption is a critical aspect of data security that involves converting plain text into coded text to protect sensitive information from unauthorized access. Here are some types of encryption and how they work:
Symmetric-key encryption uses the same key for both encryption and decryption. This type of encryption is relatively fast and efficient but requires secure key management to prevent unauthorized access.
Asymmetric-key encryption, also known as public-key encryption, uses a pair of keys – a public key and a private key – for encryption and decryption. The public key is freely available, while the private key is kept secret. This type of encryption is more secure than symmetric-key encryption as it prevents unauthorized access to the private key.
Hashing is a process of converting data into a fixed-length string of characters, known as a hash. Hashing is used to ensure data integrity and prevent unauthorized access to sensitive information. One common hashing algorithm is the Secure Hash Algorithm (SHA), which generates a 256-bit hash value for a given input.
Tokenization is a process of replacing sensitive data with a non-sensitive equivalent, known as a token. Tokens are used to protect sensitive information, such as credit card numbers, from unauthorized access. Tokenization involves replacing the sensitive data with a randomly generated token that can be used in place of the original data.
In summary, encryption, hashing, and tokenization are essential data security measures that help protect sensitive information from unauthorized access.
