Cryptography allows the following goals to be achieved:

1. Confidentiality - 

Cryptography protects the secrecy of information. Even if the transmission or storage medium has been compromised, the encrypted information will be rendered useless to an unauthorized person

2. Integrity - 

Cryptography ensures the information has not been tampered with using hashing method.

3. Authenticity -

Cryptography ensures the information sent is from intended and not a fake sender. This is done using a digital certificate, digital signature, and Public Key Infrastructure (PKI). ]]> 2021-11-19 20:56:21 UTC https://padlet.com/roja1396/2f73mk37mq92g4fc/wish/1902928124 roja1396 https://padlet.com/roja1396/2f73mk37mq92g4fc/wish/1902934232 2021-11-19 21:02:28 UTC https://padlet.com/roja1396/2f73mk37mq92g4fc/wish/1902934232 How Cybersecurity os related to cryptography roja1396 https://padlet.com/roja1396/2f73mk37mq92g4fc/wish/1902937118 Cryptography is essential to many models of cyber security. Cryptography applies algorithms to shuffle the bits that represent data in such a way that only authorized users can unshuffle them to obtain the original data. Cryptographic algorithms use mathematics to achieve effective shuffling.

Cybersecurity experts use cryptography to design algorithms, ciphers, and other security measures that codify and protect company and customer data.]]> 2021-11-19 21:05:28 UTC https://padlet.com/roja1396/2f73mk37mq92g4fc/wish/1902937118 Details of your specific focus with Cryptography focus area roja1396 https://padlet.com/roja1396/2f73mk37mq92g4fc/wish/1902939721 Encryption and Decryption

In a simplest form, encryption is to convert the data in some unreadable form. This helps in protecting the privacy while sending the data from sender to receiver. On the receiver side, the data can be decrypted and can be brought back to its original form. The reverse of encryption is called as decryption. The concept of encryption and decryption requires some extra information for encrypting and decrypting the data. This information is known as key. There may be cases when same key can be used for both encryption and decryption while in certain cases, encryption and decryption may require different keys.]]> 2021-11-19 21:08:01 UTC https://padlet.com/roja1396/2f73mk37mq92g4fc/wish/1902939721
