Cryptography and network security online chapters

  • How cryptography is used in network security?

    Cryptography ensures confidentiality by encrypting sent messages using an algorithm with a key only known to the sender and recipient.
    A common example of this is the messaging tool WhatsApp, which encrypts conversations between people to ensure they cannot be hacked or intercepted..

  • How cryptography is used in websites?

    Crytographic techniques can be used to disbribute a list of authorized users that is all but impossible to falsify.
    Confidentiality.
    Encryption is used to scramble information sent over networks and stored on servers so that eavesdroppers cannot access the data's content..

  • How does cryptography help in securing online transactions?

    Cryptography can ensure the confidentiality and integrity of both data in transit as well as data at rest.
    It can also authenticate senders and recipients to one another and protect against repudiation.
    Software systems often have multiple endpoints, typically multiple clients, and one or more back-end servers..

  • Information Security book by William Stallings

    Cryptography ensures the integrity of data using hashing algorithms and message digests.
    By providing codes and digital keys to ensure that what is received is genuine and from the intended sender, the receiver is assured that the data received has not been tampered with during transmission..

  • What is cryptography & Network Security?

    Confidentiality, Data Integrity, Authentication, and Non-Repudiation are the main principles of cryptography.
    Network security is the actions taken or procedures followed to protect the computer network.
    Cryptography ensures data confidentiality and provides data protection from unauthorized access..

  • What is idea in cryptography and network security?

    In cryptography, the International Data Encryption Algorithm (IDEA), originally called Improved Proposed Encryption Standard (IPES), is a symmetric-key block cipher designed by James Massey of ETH Zurich and Xuejia Lai and was first described in 1991..

  • What is the course description for cryptography and network security?

    The aim of this course is to introduce the student to the areas of cryptography and cryptanalysis.
    This course develops a basic understanding of the algorithms used to protect users online and to understand some of the design choices behind these algorithms..
