Latest Patents

Iwaya’s listed inventions address data protection and secure network connections.

“Encrypting and Storing Data” describes methods and apparatus that generate multiple keys from a shared secret between user equipment and a server. The keys include at least one perfect forward secrecy key and one limited forward secrecy key. The invention uses one or more of these keys to encrypt data, which can then be stored on the user equipment or transmitted to the server. The approach is designed to offer different balances of security and usability.

“Method and Apparatus for Securing a Connection in a Communications Network” concerns a user equipment device operating with a Generic Bootstrapping Architecture. The device establishes a shared secret with a Network Application Function and obtains parameters and a bootstrapping transaction identifier through an authentication process involving a Bootstrapping Server Function. It derives a modified parameter and uses it to determine a cryptographic key, which then secures communications with the Network Application Function.

Career Highlights

Iwaya’s patent work reflects an emphasis on cryptography, key derivation, and secure communications. The inventions address both the protection of stored or transmitted data and the establishment of secure connections in communications networks.

Collaborations

His listed coworkers include Marcos Antonio Simplicio Junior and Mats Näslund. His company affiliation connects his work with Ericsson’s telecommunications and network technology activities.

Conclusion
