Lecture Cryptography and network security: Chapter 8
Lecture Cryptography and network security: Chapter 8 after studying this section will help you understand: To show how modern standard ciphers, such as DES or AES, can be used to encipher long messages. To discuss five modes of operation designed to be used with modern block ciphers. To define which mode of operation creates stream ciphers out of the underlying block ciphers.

Variant of OTP Cipher with symmetric key solution
The paper proposes a solution to construct symmetric–key cryptographic algorithms based on OTP cipher developed based on the cipher One – Time Pad (OTP). Advantages of the algorithms built according to the proposed new solution is to have secure and efficient implementation as OTP cipher, but the establishment, management - distribution and usage of keys are exactly the same as the Symmetric key cryptosystems in practice (DES, AES,...).

Ebook Data-Driven Block ciphers for fast telecommunication systems
Data-Driven Block ciphers for fast telecommunication systems. Among different directions of applied cryptography, the cipher design based on the data-driven operations (DDOs) is, by comparison, poorly represented in the published and available literature.
