Bleeping Computer reported that a new proposal submitted to the Internet Engineering Task Force (IETF) defines a secure framework for delivering firmware updates to Internet of Things (IoT) devices. Insecure software updates for embedded devices (aka ‘firmware’) have been a frequent source of security lapses on mobile and embedded devices like Internet connected webcams. Filed on October 30, the “IoT Firmware Update Architecture,” establishes security requirements for device makers to implement when designing firmware update mechanisms for connected devices. A familiar list of features The proposed rules include features that have long been recommended by security experts to permit safe handling of software updates. Among them the use of cryptographically signed updates and public key cryptography to provide end-to-end security and verify firmware images, as well as the ability to work with low-power and resource constrained IoT devices. Firmware has been the source of widespread security issues. For example, low-cost […]
In-brief: Governments may worry about the democratization of strong encryption. But a bigger problem may be that the encryption we think is strong really isn’t, says Richard Moulds of the firm Whitewood. In this podcast, we talk about the.growing difficulty of generating truly random numbers in cloud environments and on the Internet of Things and how ‘entropy as a service’ may be the answer.
In-brief: Far from ‘breaking’ the public key encryption (PKI) model, the Internet of Things is poised to turbocharge PKI adoption and revolutionize online identity, DigiCert CTO Dan Timpson writes.
In-brief: GlobalSign became the latest certificate authority to say that it can now do PKI certificate issuance at massive scale, providing a way to manage identities for the Internet of Things.
In-brief: In this Security Ledger podcast, we speak with the guys from Chain of Things, a new consortium that is investigating applications of Block Chain and related technologies to solving identity and security problems for IoT deployments.
