ABSTRACT:
Methods and apparatus for finding a shared secret without compromising non-shared secrets are disclosed. The methods and apparatus receive a first group of hashed secrets from a communication device and compare the first group of hashed secrets to a second group of hashed secrets associated with an application server. A shared secret is identified among the first and second groups of hashed secrets. An application associated with the shared secret is sent to the communication device via a communication channel.
