Integrated cryptographic module providing confidentiality and integrity

摘要

An integrated cryptographic apparatus providing confidentiality and integrity includes an integrated cryptographic module including confidentiality and integrity. Further, the integrated cryptographic apparatus includes a hash function unit for detecting whether a message is modified by using the integrated cryptographic module. Furthermore, the integrated cryptographic apparatus includes a block cipher unit for constructing a data encryption algorithm by using the integrated cryptographic module.

1. An integrated cryptographic apparatus providing confidentiality and integrity comprising:
an integrated cryptographic module to receive an input bit string, and to output an output bit string after subjecting at least a portion of the input bit string to a hash function and to a block cipher in an integrated manner; a hash function generator to detect whether a message is modified by using at least a portion of the input bit string received by the integrated cryptographic module; and a block cipher generator to construct a data encryption algorithm by using at least a portion of the input bit string received by the integrated cryptographic module, wherein the integrated cryptographic apparatus further includes at least one processor configured to execute one or more operations of the integrated cryptographic module, the hash function generator, and the block cipher generator.
