1. A computing system, comprising:
a security processor configured to generate a key and generate user data by encrypting original data based on the key;
a secure memory accessible only to the security processor;
a system memory different from the secure memory, configured to store the user data in any one of a plurality of secure areas; and
a memory controller configured to manage the system memory,
wherein the security processor is configured to generate a key list comprising an authorized user identification (ID) of an authorized user having authority to access the user data, area information about an area of the system memory in which the user data is stored, and the key used to encrypt the original data,
wherein the security processor is further configured to allow access to the user data based on the generated key list, and
wherein the generated key list is stored in the secure memory.
