Transparent data encryption technology is asymmetric key secured encryption method use to encrypt data and log files. TDE encrypts SQL server Azure SQL Database, and Azure SQL Data warehouse files, known as encrypting data at rest. This technology employed by Microsoft, IBM and oracle, to deal with most critical to those threats to which data is vulnerable. The market is analyzed on the basis of types, types of keystore, by uses, and by their end users. On the basis of types market is TDE column encryption, TDE tablespace encryption. Keystores segmented it into Password-based software keystores, Auto-login software keystores and others. Transparent data encryption uses are for Authentication, Validation, Data Protection and others. Services it provides in different area such as government sector, organizations, public secto...
