The present disclosure configures a mutual security function for storing an encrypted public key in a security card (E-card), and storing a private key, which can decrypt the encrypted public key, in a mobile terminal. Accordingly, a security function that is strengthened to the next level is achieved which: only allows secure access at an entrance by means of a mutual certification procedure through an NFC connection between the security card and the mobile terminal; increases the security efficiency of access management while preventing the security of a secure server from being neutralized by an information leak that has occurred due to the loss, theft, hacking, duplication, or the like of the security card; and in particular, fundamentally prevents abnormal connections by third parties to IoT equipment that can be connected to the secure server as a result of the neutralization of security."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Access security system using security card and mobile terminal, and security method for same","description":"Disclosed are an access security system using a security card and a mobile terminal, and a security method for same.
