Cryptographic techniques are used to ensure secrecy and integrity of data in the presence of an adversary. Based on the security needs and the threats involved, various cryptographic methods such as symmetric key cryptography or public key cryptography can be used during transportation and storage of the data.
Cryptography protects the confidentiality of information
Confidentiality is necessary for maintaining the privacy of those whose personal information is stored in enterprise systems. Encryption, therefore, is the only way to ensure that your information remains secure while it’s stored and being transmitted.
