bq26100 SHA-1/HMAC-based security and authentication IC with an SDQ interface 1 1 Features 1• Provides authentication of battery packs through SHA-1 engine based HMAC • 160-byte one-time programmable (OTP), 16-bytes EEPROM • Internal time-base eliminates external crystal oscillator • Low-power operating modes: – Active: < 50 μA

TI’s BQ26100 is a SHA-1/HMAC Based Security & Authentication IC w/SDQ Interface. Find parameters, ordering and quality information.

Jun 13, 2007 · The DS2703 employs the Secure Hash Algorithm (SHA-1) specified in the Federal Information publication 180-1 and 180-2, and ISO/IEC 10118-3. SHA-1 is designed for authentication—just what is required for identifying battery …

The security is achieved using the SHA-1 hash function inside the widely adopted keyed-hash message authentication code (HMAC) construction. A unique 128-bit key is stored in each bq26100 device, allowing the host to authenticate each pack. The bq26100 device communicates to the system over a simple one-wire bi-directional serial interface.

Sep 10, 2002 · SHA-1 is nonreversible, collision-resistant, and has a good avalanche effect. SHA is a standard specified in Federal Information Publication 180-1 and 180-2 (FIPS 180-1, FIPS 180-2). The SHA series hashes are currently the only FIPS-approved method. SHA-1 is also specified in ISO/IEC 10118-3.

Jun 7, 2002 · This document shows why 1-Wire ® and iButton ® SHA-1 devices are secure by introducing possible attack scenarios and explaining how the SHA-1 devices counter the attack in hardware or in a recommended usage procedure. Data and hardware authentication with 1-Wire devices are the key concepts presented for various types of service applications ...

To achieve a high level of authentication, a more sophisticated algorithm such as the SHA-1/HMAC secure hash algorithm can be used. The SHA-1/HMAC has been used for years to authenticate Internet transactions for Virtual Private Networks, banking, and digital certificates. The algorithm used in SHA-1/HMAC is iterative.

Sep 14, 2007 · The SHA1 core is a high-performance implementation of the SHA-1 Secure Hash message digest Algorithm. This one-way hash function conforms to the 1995 US Federal Information Processing Standard (FIPS) 180-1. It accepts a large, variable-length message and produces a fixed-length message authorization code.
