One disclosed example involves a client device joining a videoconferencing meeting in which there is end-to-end encryption, where the end-to-end encryption is implemented by the client devices participating in the meting using a meeting key provided by the meeting host. Thereafter, the client device receives a public key of an asymmetric key pair corresponding to the host of the meeting, where the public key is different from the meeting key. The client device then generates a security code based on the public key and output the security code on a display device. The security code can be compared to another security code generated by another client device participating in the meeting to verify if the meeting is secure. The client device may also receive encrypted videoconferencing data, decrypt it using the meeting key, and output the decrypted videoconferencing data on the display device.

Disclosed is a method for creating one or more passwords, each in compliance with website or file requirements, from a single password containing only letters. Several parameters, including the total number of characters, any type of required character, including capital letters, digits, and special characters, and the number of each type of required character are entered in to a cipher algorithm. The cipher algorithm creates a set of possible characters from the letters of the alphabet, digits, and any special characters. According to the ruleset for the character position, the available characters from the set are made available for assignment for a predetermined period, and assigned by keystroke.

Examples associated with cryptographic key security are described. One example system includes a secure storage accessible to a basic input/output system (BIOS). A BIOS security module stores an authorization value in a fixed location in the secure storage. The authorization value is stored by the BIOS during a boot of the system. A cryptographic key module reads the authorization value from the fixed location, overwrites the authorization value in the fixed location, and obtains a cryptographic key using the authorization value.

A secure method and/or system allowing a user to import, export, recover and use their private keys based in part on the user's location information, to allow for reliable, consistent, and easy management of user identity and private keys across all of a user's devices and eliminate of traditional username/password authentication schemes.

A system and method for distributing data over a plurality of remote storage nodes. Data are split into segments and each segment is encoded into a number of codeword chunks. None of the codeword chunks contains any of the segments. Each codeword chunk is packaged with at least one encoding parameter and identifier, and metadata are generated for at least one file and for related segments of the at least one file. The metadata contains information to reconstruct from the segments, and information for reconstructing from corresponding packages. Further, metadata are encoded into package(s), and correspond to a respective security level and a protection against storage node failure. A plurality of packages are assigned to remote storage nodes to optimize workload distribution. Each package is transmitted to at least one respective storage node as a function iteratively accessing and retrieving the packages of metadata and file data.

Systems and methods related to a bridge application that facilitates interoperability between a remotely-served application and locally connected peripheral devices. The bridge application may execute on a local machine and be addressable at the loop-back address of the local machine. Requests issued to the bridge application may be verified as originating from a trusted source. In turn, requests from a locally performed and remotely-served application may be issued to local hardware resources such as peripheral devices or the like.

A device may receive, from a client device, a request with a single packet authorization (SPA) packet that includes data identifying a universal client device identifier. The device may generate a shared key associated with the universal client device identifier, and may determine that the SPA packet matches a comparison message authentication code (MAC) generated based on the shared key. The device may provide, based on the SPA packet matching the comparison MAC, a MAC associated with the SPA packet to the client device to enable the client device to validate the device.

Example embodiments of systems and methods for data transmission system between transmitting and receiving devices are provided. In an embodiment, each of the transmitting and receiving devices can contain a master key. The transmitting device can generate a diversified key using the master key, protect a counter value and encrypt data prior to transmitting to the receiving device, which can generate the diversified key based on the master key and can decrypt the data and validate the protected counter value using the diversified key.

A system for tracking an asset including one or more processing devices that identify a spatial region in a complex number space, the spatial region being associated with the asset, receive a user defined password, identify a plurality of key locations within the spatial region at least in part using the user defined password, calculate key numerical values at each of the plurality of key locations using a defined complex number formula and use the key numerical values to generate an encryption key. The asset can be associated with a user by storing an asset record in a database which is indicative of an asset identifier, the spatial region and an encrypted payload derived using the encryption key.
