Cryptopgraphic ICs have hardware features to maximise attack-resistance

Altis has announced it will sample new products using state-of-the-art cryptology and technologies to address security and performances for mobile and connected devices, by the end of this year.

The company is developing the PLM IC: a hardware crypto chip that embeds a high performance, small-footprint secure 32bit RISC processor and several high-end symmetric and asymmetric encryption engines, as well as a true random number generator and memories. Some of these blocks are: AES 256 with 8 modes (ECB, CBC, OFB, CFB, CTR, CCM, GCM and XTS), RSA 4096bits, ECC, Diffie-Hellman, El-Gamal, and various SHAs. The AIS 31 robust, hardware-based true random number generator ensures generation of secure private and public keys.

This IC is hardened and can resist strng attacks and viruses, claims the manufacturer who will evaluate and have the chip certified to the ISO standard Common Criteria EAL4+.

The crypto IC encrypts/decrypts on the fly any data file or stream coming in or out of the host platform. It can be used for strong authentication. Data can also be hashed, for integrity control. It can be used for strongly secure PKI (Public Key Infrastructure) solutions, as well as signature and certificates.

Its high data transfer rate of 100 Mb/sec (both ways) and low consumption will it an advantage over other products, in secure solutions for mobile or connected devices.

Altis is also developing the Authent'IC µSD100, a chip that comes as a µSD package embedding the PLM crypto chip and a flash memory. The µSD package can be plugged into any µSD slot of an Android mobile device for secure storage and corporate BYOD (Bring Your Own Device) enablement. Memory size is initially 4GB and can be partitioned by end user, enabling the storage of secure and non-secure data on the same card. Other versions will come with USB interface, support of Windows, increased flash memory size.

The Authent’IC µSD100 will be delivered with a robust password manager, enabling users to safely manage many secure applications with only one password. A development kit will be available to develop security applications.
