    NIOS had a cumulative enrollment of about 15 lakh (1.5 million) students from 2004 to 2009 at secondary and senior secondary levels and enrolls about 3.5 lakh (350k) students annually which makes it the largest open schooling system in the world. NIOS is a governing body just like any other Indian government official department [3]

    All India Secondary School Examination, commonly known as the class 10th board exam, is a centralized public examination that students in schools affiliated with the Central Board of Secondary Education, primarily in India but also in other Indian-patterned schools affiliated to the CBSE across the world, taken at the end of class 10. The board ...

  5. Theoretical computer science - Wikipedia

    en.wikipedia.org/wiki/Theoretical_computer_science

    Modern cryptography is heavily based on mathematical theory and computer science practice; cryptographic algorithms are designed around computational hardness assumptions, making such algorithms hard to break in practice by any adversary. It is theoretically possible to break such a system, but it is infeasible to do so by any known practical ...

  6. Cryptanalysis - Wikipedia

    en.wikipedia.org/wiki/Cryptanalysis

    Reconstruction of the appearance of cyclometer, a device used to break the encryption of the Enigma machine.Based on sketches in Marian Rejewski's memoirs.. Cryptanalysis (from the Greek kryptós, "hidden", and analýein, "to analyze") refers to the process of analyzing information systems in order to understand hidden aspects of the systems. [1]

  7. Alice and Bob - Wikipedia

    en.wikipedia.org/wiki/Alice_and_Bob

    The first mention of Alice and Bob in the context of cryptography was in Rivest, Shamir, and Adleman's 1978 article "A method for obtaining digital signatures and public-key cryptosystems." [ 2 ] They wrote, "For our scenarios we suppose that A and B (also known as Alice and Bob) are two users of a public-key cryptosystem".

  8. Cipher - Wikipedia

    en.wikipedia.org/wiki/Cipher

    asymmetric key algorithms (Public-key cryptography), where two different keys are used for encryption and decryption. In a symmetric key algorithm (e.g., DES and AES), the sender and receiver must have a shared key set up in advance and kept secret from all other parties; the sender uses this key for encryption, and the receiver uses the same ...

  9. Transposition cipher - Wikipedia

    en.wikipedia.org/wiki/Transposition_cipher

    Step-by-step process for the double columnar transposition cipher. In cryptography, a transposition cipher (also known as a permutation cipher) is a method of encryption which scrambles the positions of characters (transposition) without changing the characters themselves.
