Patent number: 8489888Abstract: A processor apparatus capable of operating in a security mode includes a hash value storage unit and a security control unit including a plurality of access authentication hash values. The hash value storage value stores a plurality of hash values including a user authentication hash value and a plurality of access authentication hash values. The security control unit checks whether a boot code transmitted from a boot memory and a hash value from among the hash values, which corresponds to the boot code, are identical, and determines whether a boot operation and a debugging operation of the processor apparatus are allowed and whether an external user is allowed to have access to a predetermined intellectual property (IP) block. The processor apparatus can ensure debugging, security for the processor itself or security for a predetermined block included in the processor apparatus.Type: GrantFiled: March 6, 2009Date of Patent: July 16, 2013Assignee: Samsung Electronics Co., Ltd.Inventor: Min-soo Lim
