- Introduce a new variable called innodb_encrypt_temporary_tables which is a boolean variable. It decides whether to encrypt the temporary tablespace. - Encrypts the temporary tablespace based on full checksum format. - Introduced a new counter to track encrypted and decrypted temporary tablespace pages. - Warnings issued if temporary table creation has conflict value with innodb_encrypt_temporary_tables - Added a new test case which reads and writes the pages from/to temporary tablespace.
