    Abstract: A method of securing user credentials in a remote repository is provided. In accordance with one embodiment, there is provided a method comprising generating a first private key and a first public key pair from a registered password; generating a second private key and a second public key pair; generating a storage key from the second private key and the first public key; encrypting a set of credentials using the storage key; creating a encrypted credential signature from the encrypted set of credentials and the first private key; and storing the encrypted set of credentials, the encrypted credential signature, and the second public key in the remote repository.

    Abstract: A modified Chinese State Encryption Management Bureau's SM2 Elliptic Curve Signature Algorithm that offers partial message recovery and lowers the signature size for a given cryptographic strength. The modified SM2 Elliptic Curve Signature Algorithm includes a signature and verification algorithm that modifies a signature generation primitive to compute a key derived from the ephemeral signing key, and a multiple of the signer's public key.

    Abstract: Methods, systems, and computer programs for performing key agreement operations in a communication system are described. In some aspects, a wireless network operator receives a mobile device identifier and accesses a secret key associated with the mobile device. A message authentication code function is evaluated based on the secret key to produce an output value. A session key and a challenge value are obtained based on the output value. In some aspects, a mobile device accesses a secret key in response to receiving the challenge value from the wireless network operator. A message authentication code function is evaluated based on the secret key to produce an output value. A response value and a session key are obtained based on the output value. The response value is transmitted to the wireless network operator.
