Abstract: Methods and systems are provided for decrypting and/or encryption information received by and/or transmitted from an integrated circuit (IC) device input/output (I/O) interface. A decryption circuit is configurable to apply a first decryption algorithm selected from a plurality of decryption algorithms to received information. An encryption circuit is configurable to apply a first encryption algorithm selected from a plurality of encryption algorithms to transmitted information. A key wrapping circuit is configurable to wrap decryption and/or encryption keys associated with the first decryption and/or encryption algorithm. A firewall circuit is configurable to prevent unauthorized access to the wrapped decryption and/or encryption keys. The decryption and/or encryption circuits are reconfigurable to apply a second decryption algorithm and/or a second encryption algorithm to the received information and/or the transmitted information.
