A method of generating a Personal Identification Number (PIN) between a first device and a second device in a network is provided. The method includes securely receiving information of input choices of the second device and random numbers assigned to the input choices at the first device. At the first device, the PIN is generated from the random numbers, and instructions are provided directing an entry of the input choices on the second device. At the second device, the input choices are entered. The second device is operable to generate the PIN from the input choices and the random numbers if the input choices are entered as instructed.

1. A method of generating, a Personal Identification Number (PIN) between a first device and a second device in a network, the method comprising: at the first device, wirelessly and securely receiving information indicative of one or more manual input choices of the second device;at the first device
1. A method of generating, a Personal Identification Number (PIN) between a first device and a second device in a network, the method comprising: at the first device, wirelessly and securely receiving information indicative of one or more manual input choices of the second device;at the first device, generating the PIN from the information for the one or more manual input choices of the second device;at the first device, providing instructions directing an entry of the one or more manual input choices on the second device, wherein the instructions are provided as at least one of an audio presentation and a visual presentation; andat the second device, entering one or more manual input choices in response to the instructions provided by the first device, wherein the second device is operable to generate the same PIN from the entered one or more manual input choices if the entered one or more manual input choices are entered as instructed. 2. The method of claim 1, wherein the information for the one or more input choices further includes numbers assigned to the input choices, and at the first device, generating the PIN further comprises: generating the PIN from the one or more input choices and the numbers assigned to the input choices. 3. The method of claim 2, wherein the second device is operable to generate the PIN from the entered input choices and the numbers assigned to the input choices. 4. The method of claim 3, wherein the numbers assigned to the input choices are random numbers. 5. The method of claim 4, wherein the random numbers include a random number generated for each input choice and generating the PIN from the random numbers further comprises: determining a random sequence of the one or more input choices, wherein the random sequence includes a sequence of input choice, random number pairs; anddetermining the PIN from the random sequence. 6. The method of claim 1, further comprising: at the first device, verifying whether the input choices entered on the second device are the same input choices in the instructions, wherein the PIN is verified when the input choices are the same. 7. The method of claim 1, wherein the entry of the input choices is performed manually on the second device. 8. The method of claim 1, wherein the input choices comprise a set of manually-activated buttons on the second device. 9. The method of claim 1, wherein the input choices comprise a set of buttons or a number of clicks of at least one button on the second device. 10. The method of claim 1, wherein the network is a Wireless Home Digital Interface (WHDI) network including end user home devices. 11. The method of claim 1, further comprising: concatenating the numbers to generate the PIN. 12. The method of claim 11, further comprising: transforming or modifying the numbers before being concatenated. 13. The method of claim 1, further comprising: sending a request to the second device from the first device before receiving the information including the input choices of the second device. 14. The method of claim 1, wherein the first device and the second device are a sink device and a source device respectively, or the first device and the second device are a source device and a source device respectively. 15. At least one non-transitory computer readable storage medium storing at least one computer program that when executed performs a method of generating a Personal Identification Number (PIN) between a first device and a second device in a network, the method comprising:at the first device, wirelessly and securely receiving information indicative of one or more manual input choices of the second device;at the first device, generating the PIN from the information for the one or more manual input choices of the second device;at the first device, providing instructions directing an entry of the one or more manual input choices on the second device, wherein the instructions are provided as at least one of an audio presentation and a visual presentation; andat the second device, entering one or more manual input choices in response to the instructions provided by the first device, wherein the second device is operable to generate the same PIN from the entered one or more manual input choices if the entered one or more manual input choices are entered as instructed. 16. The at least one non-transitory computer readable medium of claim 15, wherein the information for the one or more input choices further includes numbers assigned to the input choices, and at the first device, generating the PIN further comprises: generating the PIN from the one or more input choices and the numbers assigned to the input choices. 17. The at least one non-transitory computer readable medium of claim 15, wherein the wherein the second device is operable to generate the PIN from the entered input choices and the numbers assigned to the input choices.
