Abstract
A security method based on a memory unit for a user is provided. The security method includes receiving, from a server, a security code including a security service command for the user terminal and verification information certifying the security service command; determining whether the received verification information matches verification information stored in the memory unit; and performing, by the memory unit, a security action corresponding to the security service command, when the received verification information matches the stored verification information.
Claims20
A security method based on a memory unit for a user terminal, the security method comprising:
- receiving, from a server, a security code including a security service command for the user terminal and verification information certifying the security service command;
- determining whether the received verification information matches verification information stored in the memory unit;
- and
- performing, by the memory unit, a security action corresponding to the security service command, when the received verification information matches the stored verification information.
A user terminal supporting a security service, the user terminal comprising:
- a memory unit that performs a security function;
- a transceiver unit that receives a security code including a security service command for the user terminal and verification information certifying the security service command;
- and
- a control unit that forwards a received security code to the memory unit,
- wherein the memory unit includes a memory controller that determines whether received verification information matches stored verification information and performs the security action corresponding to the received security service command, when the received verification information matches the stored verification information.
A method for providing a secure area in a memory unit, the method comprising:
- receiving a first command requesting access to the secure area;
- permitting access to the secure area, when the first command matches preset secure area access permission information;
- allocating, in the secure area, a memory space corresponding to a read or write command;
- receiving a second command requesting to block access to the secure area;
- and
- blocking access to the secure area, in response to the second command.
A secure memory unit comprising:
- a nonvolatile memory that stores cipher keys and data;
- and
- a memory controller that controls a process of receiving a first command requesting access to a secure area, permitting access to the secure area, when the first command matches preset secure area access permission information, allocating a memory space corresponding to a read or write command in the secure area, receiving a second command requesting to block access to the secure area, and blocking access to the secure area, in response to the second command.
