Secure communications system for direct transfer between mobile device

A mobile device app computer program product (APP) for sending and encrypted files via a Wi-Fi Direct communications channel between a first mobile device and a second mobile device, the APP tangibly embodied in a computer readable medium and containing instructions that, when executed by the first mobile device, cause a processor to perform operations comprising:

• retrieving a file from data memory in the first mobile device;
• generating a symmetric key;
• encrypting the retrieved file using the generated symmetric key;
• and,
• encrypting the generated symmetric key using a public key associated with a second mobile device;
• sending the encrypted file and the encrypted symmetric key directly to the second mobile device via a direct communications channel, the APP containing instructions that, when executed by the second mobile device, cause a processor to perform operations comprising:
• receiving an encrypted file and an encrypted symmetric key directly from the second mobile device via a Wi-Fi Direct communications channel;
• decrypting the received encrypted symmetric key using a private key associated with the first mobile device;
• decrypting the received encrypted file using a decrypted symmetric key;
• and,
• storing the decrypted file to data memory in the second mobile device.

A computer program product (CPP) tangibly embodied in a computer readable medium and containing instructions that, when executed, cause a processor to perform operations to send and receive encrypted files from a first wireless device directly to a second wireless device, the operations comprising:

• retrieving a file from data memory in the first wireless device;
• generating a symmetric encryption key;
• encrypting the retrieved file using the generated encryption key;
• sending the encrypted file directly to another device via a direct communications channel;
• receiving an encrypted file directly from another device via a Direct communications channel;
• decrypting the received encrypted file using a decryption key;
• and,
• storing the decrypted file to data memory in the second wireless device.
