Abstract
Techniques and mechanisms for exchanging encrypted communications wirelessly with an accommodation-capable eye-mountable device (EMD). In an embodiment, a controller of the EMD is configured to encrypt data to be sent from the EMD to an auxiliary device or to decrypt data received by the EMD from the auxiliary device. Cryptographic operations to securely exchange the communications are based on a key value and a vector determined at the EMD. In another embodiment, the auxiliary device operates as a master, and the EMD operates as a slave, at least with respect to enablement of a functionality of the EMD to change an association of a cryptographic key value with a vector.
