Data Encryption

Data Encryption

• Encryption is the conversion of electronic data into another form, called ciphertext, which cannot be easily understood by anyone except authorized parties.
• The primary purpose of encryption is to protect the confidentiality of digital data stored on computer systems or transmitted via the Internet or other computer networks. 
• Modern encryption algorithms play a vital role in the security assurance of IT systems and communications by following the below steps.
• Authentication: the origin of a message can be verified.
• Integrity: proof that the contents of a message have not been changed since it was sent.
• Non-repudiation: the sender of a message cannot deny sending the message.
