The novel Copay wallet industrial plant amongst 3 novel technologies: Intel® Software Guard Extensions (SGX), Intel® Identity Protection Technology (IPT) too Intel® Protected Transaction Display (PTD).
Intel’s SGX extension essentially allows sensitive information too operations - similar wallet somebody keys too transaction signing - to stimulate got house inwards a secure environment, away from OS software components that may live on compromised amongst keyloggers. “For Copay users amongst desktop wallets, this agency that bitcoin somebody cardinal generation, bitcoin transaction signing, too somebody cardinal storage are secured – fifty-fifty if the Copay wallet's code is compromised or the automobile is infected amongst a virus or malware,” says BitPay
BitPay’s Copay wallet makes utilisation of Intel’s PTD & IPT technology, which throws upwardly a randomly-arranged keypad for users to travel into a 4-digit pivot code, earlier whatever of import functioning takes place:
“Each fourth dimension this PIN pad appears, the keys volition look inwards a unlike order. This presentation helps to preclude potential attackers from detecting user PINs amongst mouse-click location display coordinates.”Code that is executed inside the SGX enclave is too protected from virus infections inwards BIOS, VMM too drivers, giving Copay users the same degree of protection equally other hardware bitcoin wallets similar TREZOR & Ledger.
At press time, the hardware-level safety is non available on Copay, however, Bipay has said at that spot is an ongoing collaboration amongst Intel to deliver this functionality inwards the nigh future.
