Random Number Generator (RNG) techniques are often the best choice for generating token values. Token Mapping – this is the process of assigning the created token value to its original value. To enable permitted look-ups of the original value using the token as the index, a secure cross-reference database must be constructed.
A controlled payment number, disposable credit card or virtual credit card is an alias for a credit card number, with a limited number of transactions, and an expiration date between two and twelve months from the issue date.

Cryptographic attacks that subvert or exploit weaknesses in this process are known as random number generator attacks. A high quality random number generation (RNG) process is almost always required for security, and lack of quality generally provides attack vulnerabilities and so leads to lack of security, even to complete compromise, in ...
