Abstract: Technologies are generally described for security algorithm methods in authorizing and linking devices associated with a customer. A first device can be linked to a customer account. Additional devices can be linked to the customer account. Those devices can be authenticated to perform banking operations using dual factor authentication wherein a customer's login information is a first factor and the customer using a previously authenticated device is a second factor. By using additional methods of authentication, transactions can be done more reliably and securely.

Abstract: Technologies are generally described for multi factor security authentication algorithm methods in authorizing and using client devices to perform banking transactions. A customer can register and associate a client device with their account. The customer can further create unique login information associated with their account. A customer's login information, client device, and a push confirmation must be verified for accuracy prior to allowing the customer to perform banking operations. Using multi factor authentication process, banking transactions can be performed more reliably and securely.

Abstract: Technologies are generally described for security algorithm methods in authorizing and using digital certificates to perform banking transactions. A customer can register and associate a personal identification number with a digital certificate. The personal identification number can be used by a client device to generate a certificate request. A request to perform a banking transaction along with a certificate request can be sent to a bank server, where, upon authorization of a valid certificate request, the banking operation can be performed. Using the digital certificate as one authentication factor and a customer login and password as a second authentication factor, banking transactions can be performed more reliably and securely.

Abstract: Disclosed are systems and techniques that authenticate and authorize a mobile device to conduct transactions over a network with a banking server. Once a mobile device is authenticated, the server generates a client device identifier and a secret key, which is then stored on the mobile device. In response to a transaction request sent by the mobile device, the server authorizes a session by generating a random code and communicates the random code to the mobile device. By using a combination of the secret key and the random code, the mobile device generates two keys, a hash code and a symmetrical key. The server receives the hash code and the unique client device identifier, and based upon a determination, authorizes the transaction on the banking server.

Abstract: Disclosed are systems and techniques that generate one-time passwords in a banking server in order to authenticate a mobile device for transactional functions related to a user account. At least two one-time passwords are generated at the banking server and communicated to the mobile device via different communication pathways. A first communication pathway is encrypted and a second pathway is non-encrypted.
