Patent number: 10956141Abstract: An electronic device includes a secure element in which at least one application package is installed and a processor for communicating with the secure element. The secure element further stores a list with which a part or all of identification information of the at least one application package is registered. The processor controls the secure element such that an application package indicated by the identification information registered with the list is uninstalled, in response to a specified event. Various other embodiments recognized from the specification are also possible.Type: GrantFiled: November 20, 2017Date of Patent: March 23, 2021Assignee: Samsung Electronics Co., Ltd.Inventors: Taeck Ki Lee, Dae Haeng Cho, Eun Young Kwon, Jong Su Kim, Da Som Lee

Patent number: 10735427Abstract: An electronic device and a program management method therefor are provided. The electronic device includes a communication interface, a memory, at least one processor, and a secure circuitry. The secure circuitry is configured to provide a first public key stored in the secure circuitry to the at least one processor. The at least one processor is configured to transmit the first public key to an external device and receive an encrypted secure program encrypted based on the first public key and a second public key generated by the external device, from the external device. The at least one processor is further configured to transmit the second public key and the encrypted secure program to the secure circuitry. The secure circuitry is configured to decrypt the encrypted secure program based on the second public key and a first private key which is symmetrical to the first public key.Type: GrantFiled: November 24, 2017Date of Patent: August 4, 2020Assignee: Samsung Electronics Co., Ltd.Inventors: Eun Young Kwon, Yang Keun Kim, Jong Su Kim, Taeck Ki Lee, Dae Haeng Cho, Chol Seo Park, Da Som Lee
