Finnish Company Xiphera Launches XIP1183B and XIP1183H IP Cores Solutions for Encrypted Storage

When you think of cryptographic applications, the first thing that usually comes to mind is protecting data in motion, such as protecting Internet traffic with Transport Layer Security (TLS) or securing Ethernet traffic with MACsec.

However, securing and protecting data at rest – meaning inactive data stored on any mass storage media – is equally important, especially when you consider the staggeringly large amount of data generated each day by the humankind.

To address the needs to secure data at rest, Xiphera Ltd. has expanded its product portfolio by adding 2 IP cores, XIP1183B and XIP1183H, to its offering. These cores are based on the AES-XTS, which is a popular standard for encrypting data on block-oriented storage devices and formally defined in IEEE Standard 1619-2018.

“Sensitive data at rest may well need to be secured for decades, and therefore Xiphera has focused on 256-bit security level in our AES-XTS portfolio to make them resistant even against the projected advances in quantum computing,” says Kimmo Järvinen, co-founder and CTO.

Technical details
Technically, XTS is a mode of operation, which instantiates the underlying AES block cipher twice. The encrypted data depends on the plaintext and encryption key, and also on the logical address of the data on the storage device, which means that identical plaintexts get encrypted differently at different logical addresses.

As an example of the technical features of the company’s AES-XTS IP cores, the performance-optimised version XIP1183H achieves an encryption/decryption throughput of more than 50Gb/s in high-end FPGAs, and higher throughput rates are possible by instantiating the IP core in parallel.
