Abstract

Methods and apparatuses in automatic detection of a required network key type are described. In one embodiment, a client device prompts a user for a pass phrase, receives a pass phrase and automatically determines the encryption type for the pass phrase to connect to a network. The client device then communicates with a server to authenticate the client device.

Claims

1. A method comprising:

prompting a user for a pass phrase to connect an apparatus comprising at least one processor to a network, wherein the apparatus is a hybrid wireless communication device configured to transmit and receive electronic information including phone calls through a cellular network and a WiFi network; and

wherein the network is an encrypted WiFi network and the pass phrase is encrypted into a WEP key to connect to the encrypted WiFi network;

receiving the pass phrase;

determining, automatically, by the at least one processor, a type of encryption for the pass phrase to connect to the network;

causing, at least in part, authentication of the apparatus using the type of encryption determined for the pass phrase,

wherein the determination of the type of encryption includes encrypting, automatically, the pass phrase based on each available encryption type from a plurality of available encryption types, prior to attempting authentication of the apparatus by using each respective encrypted pass phrase; and

if connecting to the encrypted WiFi network using the WEP key fails, encrypting, automatically, the pass phrase into a hexadecimal value to connect to the encrypted WiFi network.

2. The method of claim 1, wherein the wireless communication device is configured to store and to associate the pass phrase to the encrypted WiFi network.

3. The method of claim 2, wherein the wireless communication device automatically connects to the WiFi network using the pass phrase when presence of the WiFi network is detected.

4. The method of claim 1, wherein the pass phrase is a string of alphanumeric characters.

5. The method of claim 1, wherein the prompting is an automatic response to detecting the network which requires an encryption key.

6. A non-transitory computer readable storage medium carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to at least perform the following steps:

prompting a user for a pass phrase to connect the apparatus to a network, wherein the apparatus is a hybrid wireless communication device configured to transmit and receive electronic information including phone calls through a cellular network and a WiFi network, wherein the network is an encrypted WiFi network and the pass phrase is encrypted into a WEP key to connect to the encrypted WiFi network;

receiving the pass phrase;

determining, automatically, a type of encryption for the pass phrase to connect to the network;

causing, at least in part, authentication of the apparatus using the type of encryption determined for the pass phrase, wherein the determination of the type of encryption includes encrypting, automatically, the pass phrase based on each available encryption type from a plurality of available encryption types, prior to attempting authentication of the apparatus by using each respective encrypted pass phrase; and

if connecting to the encrypted WiFi network using the WEP key fails, encrypting, automatically, the pass phrase into a hexadecimal value to connect to the encrypted WiFi network.

7. The non-transitory computer readable storage medium of claim 6, wherein the wireless communication device is configured to store and to associate the pass phrase to the encrypted WiFi network.

8. The non-transitory computer readable storage medium of claim 7, wherein the wireless communication device automatically connects to the WiFi network using the pass phrase when presence of the WiFi network is detected.

9. The non-transitory computer readable storage medium of claim 6, wherein the pass phrase is a string of alphanumeric characters.

10. The non-transitory computer readable storage medium of claim 6, wherein the prompting is an automatic response to detecting the network which requires an encryption key.

11. An apparatus comprising:

at least one processor; and

at least one memory including computer program code,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following wherein the apparatus is a hybrid wireless communication device configured to transmit and receive electronic information including phone calls through a cellular network and a WiFi network;

prompt a user for a pass phrase to connect the apparatus to a network, and to receive the pass phrase;

determine, automatically, a type of encryption for the pass phrase to connect to the network, and

cause, at least in part, authentication of the apparatus,

wherein the determination of the type of encryption includes encrypting, automatically, the pass phrase based on every available encryption type from a plurality of available encryption types, prior to attempting authentication of the apparatus by using each respective encrypted pass phrase, wherein the network is an encrypted WiFi network and the pass phrase is encrypted into a WEP key to connect to the encrypted WiFi network; and

if connecting to the encrypted WiFi network using the WEP key fails, encrypting, automatically, the pass phrase into a hexadecimal value to connect to the encrypted WiFi network.

12. The apparatus of claim 11, wherein the wireless communication device is configured to store and to associate the pass phrase to the encrypted WiFi network.

13. The apparatus of claim 12, wherein the wireless communication device automatically connects to the WiFi network using the pass phrase when presence of the WiFi network is detected.

14. The apparatus of claim 11, wherein the prompt is an automatic response to detecting the network which requires an encryption key.
