What is cryptography in simple words?
Cryptography is the study of secure communications techniques that allow only the sender and intended recipient of a message to view its contents. Here, data is encrypted using a secret key, and then both the encoded message and secret key are sent to the recipient for decryption.
What is cryptography and how it works?
A cryptographic algorithm, or cipher, is a mathematical function used in the encryption and decryption process. A cryptographic algorithm works in combination with a key — a word, number, or phrase — to encrypt the plaintext. The same plaintext encrypts to different ciphertext with different keys.
What are the advantages and disadvantages of cryptography?
Advantages And Disadvantages Of Biometric Technology. Whereas,asymmetric encryption involves the use of two different but related keys-the encryption key,and decryption key However,some Information Communication Technology experts have
What is cryptography and how is it related to computers?
In computer science, cryptography refers to secure information and communication techniques derived from mathematical concepts and a set of rule-based calculations called algorithms, to transform messages in ways that are hard to decipher.
What you should know about cryptography?
Cryptography is the process of securing information by hiding and converting data in a form that only authorized people can read, comprehend, and evaluate. Cryptography intends to make data unreadable for those who do not have a way to interpret it by changing raw information into modulated data.
What are the objectives of cryptography?
C-Confidentiality: Ensuring the information exchanged between two parties is confidential between them and is not visible to anyone else.
