Unpredictability is a key security feature of tokenization!

Unpredictable means that the token is generated in a way that is highly unlikely to be guessed or predicted by an attacker. This is achieved through the use of:

1. Randomized algorithms

2. High-entropy inputs (e.g., large random numbers)

3. Secure key management

Unpredictability makes it extremely difficult for attackers to:

1. Guess the token

2. Perform a brute-force attack

3. Use a rainbow table attack

By making the token unpredictable, tokenization ensures that even if an attacker has some information about the original PAN, they cannot predict the token. This significantly reduces the risk of unauthorized access to sensitive payment card data.

Unpredictability is a critical security feature of tokenization, making it an effective way to protect sensitive data and prevent attacks!
