  • How is cryptography used in 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..

  • Types of cryptographic functions

    Provides cryptographic services, including secure encoding and decoding of data, as well as many other operations, such as hashing, random number generation, and message authentication..

  • Types of cryptography

    THE IMPORTANCE OF CRYPTOGRAPHY
    This allows the information to remain secure and enables parties to send and receive complex messages.
    The authorized party has a cipher, commonly known as a key, which decodes the unreadable data so it appears in its original form..

  • What is computer security and cryptography?

    Cryptography is the process of hiding or coding information so that only the person a message was intended for can read it.
    The art of cryptography has been used to code messages for thousands of years and continues to be used in bank cards, computer passwords, and ecommerce..

  • What is cryptology in computer security?

    Cryptology is the science of secure communications.
    Cryptography creates messages with hidden meaning; cryptanalysis is the science of breaking those encrypted messages to recover their meaning..

  • What is the difference between cryptography and computer security?

    While Cryptography is a technique used to secure data by converting it into an unreadable format, Cyber Security is a practice used to protect digital devices, networks, and sensitive information from various cyber threats..

  • What is the difference between cryptography and computer security?

  • Why is security and encryption important?

    It helps protect private information, sensitive data, and can enhance the security of communication between client apps and servers.
    In essence, when your data is encrypted, even if an unauthorized person or entity gains access to it, they will not be able to read it..

  • Cryptology is the science of secure communications.
    Cryptography creates messages with hidden meaning; cryptanalysis is the science of breaking those encrypted messages to recover their meaning.
Cryptography in computer network security is the process of protecting sensitive information from unauthorized access when it is at rest or in transit by rendering it unreadable without a key.
Cryptography uses encryption algorithms to transform plaintext into ciphertext, making it unreadable without the key. Similarly, Cyber Security uses encryption to secure data in transit or at rest, ensuring that only authorized parties have access to it.
In the fifteenth century, cryptography became more sophisticated and cryptographers proposed using multiple cipher alphabets, a process referred to as 
Individuals and organizations use cryptography on a daily basis to protect their privacy and keep their conversations and data confidential. Cryptography ensures confidentiality by encrypting sent messages using an algorithm with a key only known to the sender and recipient.

Number of standards related to cryptography

There are a number of standards related to cryptography.
Standard algorithms and protocols provide a focus for study; standards for popular applications attract a large amount of cryptanalysis.

Approach to public-key cryptography

Elliptic-curve cryptography (ECC) is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields.
ECC allows smaller keys compared to non-EC cryptography to provide equivalent security.

Constructions of cryptographic primitives that involve lattices

Lattice-based cryptography is the generic term for constructions of cryptographic primitives that involve lattices, either in the construction itself or in the security proof.
Lattice-based constructions are currently important candidates for post-quantum cryptography.
Unlike more widely used and known public-key schemes such as the RSA, Diffie-Hellman or elliptic-curve cryptosystems — which could, theoretically, be defeated using Shor's algorithm on a quantum computer — some lattice-based constructions appear to be resistant to attack by both classical and quantum computers.
Furthermore, many lattice-based constructions are considered to be secure under the assumption that certain well-studied computational lattice problems cannot be solved efficiently.

Overview of and topical guide to cryptography

The following outline is provided as an overview of and topical guide to cryptography:
Provable security refers to any type or level of computer security that can be proved.
It is used in different ways by different fields.
