Abstract
Techniques for two-way authentication between two communication endpoints (e.g., two devices) using a one-way out-of-band (OOB) channel are presented. Here, in embodiments, both communication endpoints may be securely authenticated as long as the one-way OOB channel is tamper-proof. Embodiments of the invention do not require the one-way OOB channel to be private to ensure that both endpoints are securely authenticated. Since providing a two-way or private OOB channel adds to the cost of a platform, embodiments of the invention provide for a simple and secure method for two-way authentication that uses only a non-private one-way OOB channel and thus helping to reduce platform cost. Other embodiments may be described and claimed.
