Method for protecting data for information centric in-network computing and system using the same

A system for protecting data for data name-based information centric in-network computing, the system comprising:

• a computing node configured to prepare an encryption key pool that includes a security key for sharing a symmetric key used for encrypting result data according to a user's request and matching information;
• and
• an INC agent configured to receive the user's request and prepare a synchronization key pool for sharing the security key through the matching information,
• wherein the computing node creates a processor for executing output processing of the result data and allocates a security key to the processor based on the matching information of the encryption key pool when the security key exists, the security key being allocated to the computing node which is determined to perform the request in the INC agent,
• wherein the INC agent and the computing node are further configured to remove the allocated security key and the matching information from the synchronization key pool and the encryption key pool when the security key is allocated to the processor, and are configured to create a new security key and new matching information.
