Abstract: The crypto hardware wallet system with a secure crypto processing environment and a secure transaction authorization device. Where the secure crypto processing environment is on a single die IC with encrypted memory that holds an encrypted entry that has sensitive data. An encryptor/decryptor is coupled to the encrypted memory and decrypts the encrypted entry using an internal security mechanism. A micro controller unit coupled to the encryptor/decryptor requests and receives the sensitive data. The micro controller unit receives a request and uses the sensitive data to fulfill the request. The internal security mechanism may include an internal cryptographic key derived from a micro radiation source. The secure transaction authorization device may include a secure computing environment and a user experience device coupled to the secured computing environment via a switch. Where the secure computing environment controls whether the user experience device is communicating to the secured processing environment.
