Apple unveils first Macs powered by its own chips

Written on Wednesday, 11 November 2020 06:16

Apple has revealed its first Mac computers powered by chips of its own design. The California-based tech giant unveiled its M1 chip and the first computers that will run on it: a new MacBook Air, 13-inch MacBook Pro, and Mac Mini.

However, the launch failed to excite investors. Apple’s value varied during the performance, with shares dropping and the big reveal failing to stall the decline. It would seem investors were unsurprised by the new product line, but this may change as we edge closer to Christmas and as global lockdowns are eased. Perhaps this can reverse Apple’s recent revenue stagnation.

In June, the company announced it would transition away from the Intel processors it had used since 2006. Putting a processor based on the ARM architecture in its desktop and laptop computers marks a big move for Apple away from Intel-designed chips and towards its own silicon, which has been used in the iPad, iPhone and Apple Watch for a number of years.

Apple said the advantages of using the M1 chip included better battery life, instant wake from sleep mode, and the ability to run iOS apps. It added it had optimized all of its own Mac apps, but now needs to convince other developers to do likewise.

This will be the first time in the 36-year history of the Mac that Apple-designed processors will power these machines. It has changed chips only two other times. In the early 1990s, Apple switched from Motorola processors to PowerPC. At WWDC in 2005, Steve Jobs announced a move from PowerPC to Intel, and Apple rolled out those first Intel-based Macs in January 2006.

According to Bloomberg, Apple’s chip-development group decided to make the switch after Intel’s annual chip performance gains slowed and engineers worried that sticking to Intel’s road map would delay or derail some future Macs.

Vendors team to develop IoT security protocol

Written on Sunday, 24 July 2016 05:44

A handful of companies led by ARM, Intercede, Solacia and Symantec, joined by Beanpod, Sequitur Labs, Sprint, Thundersoft, Trustkernel and Verimatrix have announced a jointly developed Open Trust Protocol (OTrP) for securing IoT networks.

They say that OTrP combines a secure architecture with trusted code management, using technologies proven in large-scale banking and sensitive data applications on mass-market devices such as smartphones and tablets.

Marc Canel, vice president of security systems, ARM, said: "In an internet-connected world, it is imperative to establish trust between all devices and service providers. Operators need to trust devices their systems interact with and OTrP achieves this in a simple way. It brings e-commerce trust architectures together with a high-level protocol that can be easily integrated with any existing platform."

OTrP is described as a high level management protocol that works with security solutions such as ARM TrustZone-based trusted execution environments that are designed to protect mobile computing devices from malicious attack.

OTrP is available as an IETF informational  from the IETF website for prototyping and testing, and its developers say they plan for it to be further developed by a standards defining organization that can encourage its mass adoption as an interoperable standard.

The developers says the protocol paves the way for an open interoperable standard to enable the management of trusted software without the need for a centralized database by reusing the established security architecture of e-commerce.

“The management protocol is used with Public Key Infrastructure (PKI) and Certificate Authority-based trust architectures, enabling service providers, app developers and OEMs to use their own keys to authenticate and manage trusted software and assets. OTrP is a high level and simple protocol that can be easily added to existing Trusted Execution Environments or to microcontroller-based platforms capable of RSA cryptography.”

OTrP is available from the IETF web site as an IETF informational and it is planned that it will be further developed by a standards defining organization that can encourage its mass adoption as an interoperable standard.
