| Block cipher is one of the most widely-used tool in cryptography, and its mode of operation features the use of a symmetric-key block-cipher algorithm in providing information security such as confidentiality or authenticity. Five modes of operation with AES algorithm will be discussed in this paper: Electronic Codebook (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB), Output Feedback (OFB), and Counter (CTR). These modes can provide cryptographic protection for sensitive, but classified, computer data. | How do you write an abstract? Identify your purpose. You're writing about a correlation between lack of lunches in schools and poor grades. … Explain the problem at hand. Abstracts state the “problem” behind your work. … Explain your methods. … (Source) Save your work regularly!!! Describe your results (informative abstract only). … Abstract should be no longer that 400 words.

| Block cipher is one of the most widely-used tool in cryptography, but itself is only used of one fixed-length group of bits called a block [1]. A mode of operation describes how to repeatedly apply a cipher's single-block operation to securely transform amounts of data larger than a block [2]. | |

| The five modes—the Electronic Codebook (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB), Output Feedback (OFB), and Counter (CTR) modes can provide data confidentiality. | |
