Automated secure pairing for wireless devices

摘要

Systems, methods, and/or techniques (“tools”) are described herein that relate to automated secure pairing for devices, and that relate to parallel downloads of content using devices. The tools for pairing the devices may perform authentication protocols that are based on addresses and on keys. The address-based authentication protocol may operate on address book entries maintained by the devices. The key-based authentication protocol may operate using a key exchange between the devices.

1. A method for pairing at least two devices, the method comprising:
performing, via a direct connection between the at least two devices, a first authentication protocol including:
receiving, at a target device of the at least two devices, a pairing request that includes an identifier; andcomparing, by the target device, the identifier to entries previously stored in an address book; in an event that the comparing indicates that the identifier coincides with at least one of the entries previously stored in the address book, performing, via an indirect connection between the at least two devices, a second authentication protocol including:
generating a random nonce;encrypting the random nonce using a security key;sending a challenge that includes the encrypted random nonce;receiving a challenge response that includes the random nonce that is decrypted; andcomparing the random that is decrypted and received in the challenge response to the random nonce that is generated; and determining, by the target device, to accept the pairing request based at least in part on whether the random nonce that is decrypted matches the random nonce that is generated.
