Abstract
A method and an apparatus for verifying identity of a direct communication message using asymmetric keys in a wireless communication network comprising a plurality of electronic devices is provided. The method includes distributing a public key associated with a second electronic device among a plurality of electronic devices by a Device-to-Device (D2D) server. The method includes receiving the direct communication message from the second electronic device at a first electronic device. The direct communication message comprises a digital signature generated using a private key associated with the second electronic device. Further, the method includes verifying the identity of the direct communication message using the public key associated with the second electronic device.
