The embodiments provide advantages of high reliability, high security and easy realization. | 2020-12-31 |
20200412533 | APPARATUS, SYSTEM AND METHOD FOR GENERATING AND MANAGING CRYPTOGRAPHIC KEYS FOR A SYMMETRIC CRYPTOGRAPHIC SYSTEM - Cryptographic systems and methods are disclosed, including numerous industry applications. Embodiments of the present invention can generate and regenerate the same symmetric key. The cryptographic systems and methods include a key generator configured to use two or more inputs to reproducibly generate the symmetric key and a cryptographic engine configured to use the symmetric key for encrypting and decrypting data. | 2020-12-31 |
20200412534 | PUBLIC KEY PROTECTION TECHNIQUES - Methods, systems, and devices for public key protection techniques are described. An embedded multimedia card (eMMC) may be formatted to include a permanent write protect group that is configured to prevent disabling of write protection for data stored in the permanent write protect group. The eMMC may store a public key associated with a first host device in the permanent write protect group of the eMMC. A data package may be received from the host device and authenticated by using the public key stored in the permanent write protect group. The embedded memory controller may be configured to prevent modifying or writing data to a permanent write protect group. | 2020-12-31 |
20200412535 | AUTHENTICATION INFORMATION TRANSMISSION METHOD, APPARATUS, AND STORAGE MEDIUM - This disclosure relates to an authentication information transmission method and system, a key management client, and a computer device, belonging to the field of communication technologies. The method includes: receiving, by a key management client through a preset hardware abstract layer interface, authentication information transmitted by an application client running in the computing device and associated with an application server; transmitting, by the key management client, the authentication information to a key management server, so that the key management server transmits the authentication information to a trusted application in a trusted execution environment in the computing device; obtaining, by the key management client, authentication information signed by the trusted application and forwarded by the key management server; and transmitting, by the key management client through the preset hardware abstract layer interface, the signed authentication information to the application, so that the application server performs a validity check on the authentication information. | 2020-12-31 |

20200412537 | ENCRYPTION AND DECRYPTION OF VISIBLE CODES FOR REAL TIME AUGMENTED REALITY VIEWS - A method of decrypting an encrypted message. The method comprises storing a wearer decryption code in a memory of a wearable mobile device having a head-worn augmented display which generates an augmented reality view for a wearer of the wearable mobile device, capturing using the wearable mobile device a video sequence including at least one frame imaging a visible code using an image sensor of the wearable mobile device, processing the video sequence to identify the visible code, decrypting the visible code using the wearer decryption code to create an decrypted content, and presenting the decrypted content on top of at least some of the visible code in the augmented reality view. | 2020-12-31 |
20200412538 | SERVERLESS CONNECTED APP DESIGN - A system for authorizing a serverless application function having a plurality of tenants, each tenant may include one or more entities that share a common access to a processing space and a data store. The system includes a gateway that receives a request from a tenant, an authorization component that access a public key assigned to the tenant, and a serverless processor that generates public and private keys for the tenant. The serverless processor also generates an access token for the first tenant that is signed using the private key and requests a transaction token from the authorization component using the access token. The authorization component transmits a transaction token to the serverless processor, which is used to make further requests to a virtual environment. | 2020-12-31 |
20200412539 | SYSTEMS AND METHODS FOR USER-BASED AUTHENTICATION - A device that includes a secure element or a secure environment receives a token for authenticating a user that has an account with a service provider. The device generates, based on the token, a set of keys that include at least a private key and a public key. The device performs a key authentication procedure to compare the set of keys and a configured set of keys and selects a public key, of the set of keys or the configured set of keys, based on a result of the key authentication procedure. The device causes a device identifier of the device and the public key to be provided to another device that uses the device identifier and the public key to perform an authentication procedure to authenticate the user. The device receives, from the other device, an indication of whether the device is connected to a network. | 2020-12-31 |
20200412540 | DISTRIBUTION OF SECURITY CREDENTIALS - Techniques regarding the use of digital identity tokens describing a computer application to obtain authorization to confidential data based on one or more policies are provided. For example, one or more embodiments described herein can comprise a system, which can comprise a memory that can store computer executable components. The system can also comprise a processor, operably coupled to the memory, and that can execute the computer executable components stored in the memory. The computer executable components can comprise a trusted platform module component that can generate a digital identity token that is bound to a computer application process. The computer executable components can also comprise a key authenticity component that can compare the digital identity token to a security key to retrieve a security credential. | 2020-12-31 |
