Method and System for Cryptographic Processing Core

A method in data processing system having a cryptographic processor, comprising:

• receiving an input data stream indicating a cryptographic protocol;
• receiving an indication of the cryptographic protocol by a microcontroller in the cryptographic processor;
• programming, based on the indicated cryptographic protocol, a configurable controller in the cryptographic processor that performs one of:
• (1) aligning the received input data stream;
• (2) inserting data into the input data stream;
• and (3) removing data from the input data stream;
• and
• performing one of:
• (1) encrypting and (2) decrypting on the received input data stream.

A cryptographic processor, comprising:

• an ingress section, comprising:
• an input buffer to receive an input data stream;
• and
• a first configurable controller to:
• (1) align the received input data stream;
• (2) insert data into the input data stream;
• and
• (3) remove data from the input data stream;
• an cipher engine receiving the processed input data stream from the first configurable controller and encrypting the processed input data stream;
• an authentication section, comprising:
• a second configurable controller to:
• (1) align the received input data stream;
• (2) insert data into the input data stream;
• and
• (3) remove data from the input data stream;
• an authentication engine receiving the processed input data stream from the second configurable controller and authenticating the processed input data stream;
• an egress section, comprising:
• a third configurable controller to:
• (1) align the received input data stream;
• (2) insert data into the input data stream;
• and
• (3) remove data from the input data stream;
• an output buffer to receive the processed input data stream from the third configurable controller;
• and
• a programmable microcontroller that programs the first, second and third controllers.
