Dedicated IC Simplifies Implementation of a SHA-1-Based Token Authentication System DALLAS, TX -Dallas Semiconductor introduces the DS2705, a SHA-1 authentication master. The DS2705 provides the master side of a secure hash algorithm-based (SHA) token authentication scheme and orchestrates the challenge/response sequence. This dedicated device eliminates the hardware and software development of a host implementation, thus greatly simplifying design efforts and reducing development time.
