Modes that Combine Encryption and Authentication

I need to have a research paper about one of AES, OCB, CCM or GCM block cipher modes which are some of operation designed to achieve both message privacy and authentication, by merging the features of a MAC directly into the mode.

Structure and Content: The paper should include the following components, organized in a logical flow and written as cohesive paragraphs:

1. Find one mode of operation that is designed to achieve both message privacy and authentication. Give an overview of the mode with details including its authors, date of publication, and what problems it was designed to solve. Also, try to find and cite one or more application protocols or cryptographic libraries in which the chosen mode has been implemented.

2. Describe in detail how the mode works. Do not just paste formulas in your paper; rather, give a high-level, readable English description of the operations of the mode. One good approach here is to use our hypothetical communicators, Alice and Bob, going through the procedures of message construction, transmission, decryption, and validation for one complete authenticated message. Supplement the description with your own intuitions and analysis of how these operations work to ensure different aspects of secure communication. You don't need to use a lot of math in this portion; rather, strive to present as clearly as possible an intuitive understanding of the protocol.

3. Compare and contrast the security and efficiency of your chosen mode with ECB for combining encryption and authentication, and with other modes. You can mention any known weaknesses of the scheme you find in the literature, with proper citations. Citations. All facts and claims presented should be backed up by citations to appropriate references. Wikipedia articles, news articles on technology websites, and blog postings are not appropriate sources to cite for this paper. You are welcome to use Wikipedia to find pointers to the original sources and to aid your own understanding; however, your paper must be based on the original published research. The paper should be formatted in either IEEE or APA reference styles.
