Systems and methods for establishing a trusted dynamic host configuration protocol connection
View Patent ↗A method for establishing trusted communication between a client and a server is described. The method is implemented by a computer system. A response is received from a first server. An internet protocol address of the first server is compared with at least one internet protocol address within a list. The response is validated if the internet protocol address of the first server is included within the list. Trusted communication is established between the client and the first server. The trusted communication includes assigning an internet protocol address provided by the response to the client.
1. A method for establishing trusted communication between a client and a server, the method being implemented by a computer system, the method comprising:
receiving a response from a first server;
comparing an internet protocol address of the first server with at least one internet protocol address within a list;
caching the response from the first server if the internet protocol address of the first server is not included within the list;
validating the response if the internet protocol address of the first server is included within the list;
establishing trusted communication between the client and the first server when the internet protocol address of the first server is included within the list, wherein establishing the trusted communication includes a request to assign the client an internet protocol address provided by the response to the client; and
waiting a period of time for a response from an additional server that has an internet protocol address included within the list if the internet protocol address of the first server is not included within the list, wherein, after waiting the period of time, if no response is received from the additional server, prompting a user to accept or refuse connection to the first server,
wherein if the user accepts connection, validating the cached response from the first server and establishing communication between the client and the first server, wherein the establishing communication includes a request to assign the client the internet protocol address provided by the response to the client.
2. The method of claim 1 , further comprising rejecting the response if the internet protocol address of the first server is not included within the list.
3. The method of claim 2 , further comprising receiving a second response from the additional server and comparing an internet protocol address of the additional server with the one or more than one internet protocol addresses within the list.
4. The method of claim 3 , further comprising validating the second response if the internet protocol address of the additional server is included within the list.
5. A computer system that is configured to establish trusted communication between a client and a server, the computer system comprising:
a processor;
memory in electronic communication with the processor;
instructions stored in the memory, the instructions being executable to:
receive a response from a first server;
compare an internet protocol address of the first server with one or more than one internet protocol addresses within a list;
cache the response from the first server if the internet protocol address of the first server is not included in the list;
validate the response if the internet protocol address of the first server is included within the list;
establish trusted communication between the client and the first server when the internet protocol address of the first server is included within the list, wherein establishing the trusted communication includes a request to assign the client an internet protocol address provided by the response to the client; and
wait a period of time for a response from an additional server that has an internet protocol address included within the list if the internet protocol address of the first server is not included within the list, wherein, after waiting the period of time, if no response is received from the additional server, prompting a user to accept or refuse connection to the first server,
wherein if the user accepts connection, validating the cached response from the first server and establishing communication between the client and the first server, wherein the establishing communication includes a request to assign the client the internet protocol address provided by the response to the client.
6. The computer system of claim 5 , wherein the instructions stored in the memory are further executable to reject the response if the internet protocol address of the first server is not included within the list.
7. The computer system of claim 5 , wherein the instructions stored in the memory are further executable to receive a second response from the additional server and compare an internet protocol address of the additional server with the one or more than one internet protocol addresses within the list.
8. The computer system of claim 7 , wherein the instructions stored in the memory are further executable to validate the second response if the internet protocol address of the additional server is included within the list.
9. A client configured to communicate with a server over a network, the client comprising:
a network driver configured to communicate with a server on the network;
a dynamic host configuration protocol secure connection component configured to receive communications from the network driver;
a predetermined list of parameters configured to identify the server communicating with the client; and
a memory to cache a communication from the server if an internet protocol address associated with the server is not included in the predetermined list of parameters, wherein if the internet protocol address of the server is not included within the list, the client waits a period of time for a response from an additional server that has an internet protocol address included within the list, wherein, after waiting the period of time, if no response is received from the additional server, the client prompts a user to accept or refuse connection to the server,
wherein if the user accepts connection, the client validates the cached communication from the server and establishes communication between the client and the server, wherein the establishing of communication includes a request to assign the client the internet protocol address provided by the communication to the client.
10. The client of claim 9 , wherein the predetermined list is configured to include the internet protocol address of the server or a plurality of servers on the network.
11. The client of claim 9 , wherein the dynamic host configuration protocol secure connection component is configured to compare the internet protocol address of the server with the internet protocol addresses included in the predetermined list.
12. The client of claim 9 , further configured to communicate with a server implementing dynamic host configuration protocol communications.
13. The client of claim 9 , further configured to communicate with a server implementing preboot execution communications.
14. A non-transitory processor-readable storage medium comprising executable instructions for validating a response at a client, the instructions being executable to:
receive a response from a first server;
compare an internet protocol address of the first server with one or more than one internet protocol addresses within a list;
cache the response from the first server if the internet protocol address of the first server is not included in the list;
validate the response if the internet protocol address of the first server is included within the list;
establish trusted communication between the client and the first server when the internet protocol address of the first server is included within the list, wherein establishing the trusted communication includes a request to assign the client an internet protocol address provided by the response to the client;
wait for a second response from a second server that has an internet protocol address included within the list if the response from the first server is not validated;
receive the second response from the second server and compare an internet protocol address of the second server with the one or more than one internet protocol addresses within the list; and
validate the second response if the internet protocol address of the second server is included within the list, wherein, after waiting a period of time, if no response is received from the second server, prompt a user to accept or refuse connection to the first server,
wherein if the user accepts connection, validate the cached response from the first server and establish communication between the client and the first server, wherein the establishing communication includes a request to assign the client the internet protocol address provided by the response to the client.
15. The client of claim 9 , wherein the predetermined list is configured to include the internet protocol address of the server or a plurality of servers on the network, wherein the dynamic host configuration protocol secure connection component is configured to compare the internet protocol address of the server with the internet protocol addresses included in the predetermined list, and wherein the client is further configured to communicate with a server implementing preboot execution communications.
