Performance evaluation on encrypted - non encrypted database fields containing IoT data

Encrypted data transmitted from secure wireless channels as part of Internet of Things (IoT) infrastructures are mainly stored in database tables using plaintext records. As IoT data content confidence in supportive A.I. actions radically increases, the selection and use of database encryption is essential in terms of data integrity safety as well as IoT operations or decisions validity and non repudiation. Taking into account the amount of stored IoT data, data filtering and processing overhead needed for aptly decision making, it is essential for a developer to seriously take into account encryption-decryption queries overheads for big IoT data processing tasks, as well as extra time delays on encryption-decryption operations, since these translate into idle or receiving states energy expenditures at the wireless IoT motes.
