In times of data leakage, hacker attacks, trojan horses, and various other data security threats, efficient and effective data encryption has becomes a critical requirement for many enterprises. This need applies to XML as much as to most other forms of data.
Intel and IBM have collaborated to demonstrate that a combination of modern hardware and software can perform effective encryption with very high efficiency.
In particular, the latest Intel Xeon E5 and E7 processor families provide AES-NI, which is a set of new instructions in the Intel Xeon processor that help accelerate encryption, decryption, key generation, matrix manipulation, and carry-less multiplication.
A joint benchmark has measured the performance impact of encrypting and decrypting XML data in DB2 9.7 using the IBM InfoSphere Guardium Data Encryption capabilities on the Intel Xeon E5 platform.
The results of the TPoX benchmark show that full encryption can be performed for a read/write XML transaction processing application with less than 4% overhead. This is a fantastic result.
