Key Topics

  • Lexical Analysis
    UN-2.1

    The process of breaking the source code into a series of tokens. It involves the specification and recognition of tokens, input buffer, and finite automata relevant to compiler construction.

  • Syntax Analysis
    UN-2.2

    The process of analyzing the syntax of the source code. It involves basic parsing techniques, problem of left recursion, left factoring, ambiguous grammar, top-down parsing, bottom-up parsing, and LR parsing.

  • Semantic Analysis
    UN-2.3

    The process of analyzing the meaning of the source code. It involves static and dynamic checks, typical semantic errors, scoping, type checking, syntax directed definitions, and translation.

  • Matrix Representations
    UN-2.4

    This topic explains how matrices can be used to represent and perform geometrical transformations in computer graphics. It covers the basics of matrix operations and their applications in transformation matrices.

  • Window to View Port Transformation
    UN-2.5

    This topic covers the process of transforming a window coordinate system to a view port coordinate system, including the concepts of windowing, viewing, and porting. It explains the importance of this transformation in computer graphics.

  • 3D Viewing
    UN-2.6

    This topic covers the concepts of 3D viewing, including camera models, view volumes, and projection types. It explains how 3D viewing is used to create realistic and interactive 3D graphics.

Key Topics

  • Cryptography
    UN-301

    The practice and study of techniques for secure communication in the presence of third-party adversaries. It involves the use of algorithms to transform plaintext into unreadable ciphertext.

  • Cryptanalysis
    UN-302

    The study of methods for obtaining the plaintext from the ciphertext without knowing the key. It involves breaking the encryption algorithm to access the encrypted data.

  • Cipher Structure
    UN-303

    The design and architecture of encryption algorithms, including the use of substitution and permutation techniques to transform plaintext into ciphertext.

  • Encryption Algorithms
    UN-304

    Mathematical procedures used to transform plaintext into ciphertext, ensuring confidentiality and integrity of data.

  • Data Encryption Standard (DES)
    UN-305

    A symmetric-key block cipher that was widely used for encrypting data, but is now considered insecure due to its small key size.

  • International Data Encryption Algorithm (IDEA)
    UN-306

    A symmetric-key block cipher that was designed to replace DES, but is no longer considered secure due to its vulnerabilities.

  • Advanced Encryption Standard (AES)
    UN-307

    A symmetric-key block cipher that is widely used for encrypting data, known for its high security and efficiency.

  • Modes of Operation
    UN-308

    Different ways of using a block cipher to encrypt data, including Electronic Codebook (ECB), Cipher Block Chaining (CBC), and others.

  • Symmetric Block Ciphers
