R224. Use secure cryptographic mechanisms

Requirement

The system must use the most secure cryptographic mechanism provided by the platform (e.g., java.security.SecureRandom) for random number generation used in critical processes (e.g., ID generation, code mapping, cryptographic keys).

Descriptions

System cryptographic keys are essential for maintaining the confidentiality and integrity of transactions and communications. Some of these keys and other critical elements are generated using random numbers. In these cases, the random numbers themselves must be generated using secure mechanisms, which have often already been implemented by the platform.
