问题描述
正如我们所知,安全 Enclave 是在 Apple A7 中制造的协处理器,它在 A7 及更高版本中可用,但它在 iOS 9 中公开使用 kSecAttrTokenIDSecureEnclave
但我们如何检查某些设备是否支持安全飞地与否?谢谢
As we know that secure Enclave is a coprocessor fabricated in the Apple A7 and its available in A7 and later on but its use publicly in iOS 9 kSecAttrTokenIDSecureEnclave
but how do we check either some device support secure enclave or not ?Thanks
推荐答案
我没有找到,所以我自己检查了:
I didnt find any so I made my own check:
+ (BOOL) isDeviceOkForSecureEnclave
{
double OSVersionNumber = floor(NSFoundationVersionNumber);
UIUserInterfaceIdiom deviceType = [[UIDevice currentDevice] userInterfaceIdiom];
BOOL isOSForSecureEnclave = OSVersionNumber > NSFoundationVersionNumber_iOS_8_4 ? YES:NO;
//iOS 9 and up are ready for SE
BOOL isDeviceModelForSecureEnclave = NO;
switch (deviceType) {
case UIUserInterfaceIdiomPhone:
//iPhone
isDeviceModelForSecureEnclave = [self isPhoneForSE];
break;
case UIUserInterfaceIdiomPad:
//iPad
isDeviceModelForSecureEnclave = [self isPadForSE];
break;
default:
isDeviceModelForSecureEnclave = false;
break;
}
return (isOSForSecureEnclave && isDeviceModelForSecureEnclave) ? YES:NO;
}
/**
The arrays are models that we know not having SE in hardware, so if the current device is on the list it means it dosent have SE
*/
+ (BOOL) isPhoneForSE
{
NSString *thisPlatform = [self platform];
NSArray * oldModels = [NSArray arrayWithObjects:
@"x86_64",
@"iPhone1,1",
@"iPhone1,2",
@"iPhone2,1",
@"iPhone3,1",
@"iPhone3,3",
@"iPhone4,1",
@"iPhone5,1",
@"iPhone5,2",
@"iPhone5,3",
@"iPhone5,4", nil];
BOOL isInList = [oldModels containsObject: thisPlatform];
return !isInList;
}
+ (BOOL) isPadForSE
{
//iPad Mini 2 is the earliest with SE // "iPad4,4"
NSString *thisPlatform = [self platform];
NSArray * oldModels = [NSArray arrayWithObjects:
@"x86_64",
@"@iPad",
@"@iPad1,0",
@"@iPad1,1",
@"iPad2,1",
@"iPad2,2",
@"iPad2,3",
@"iPad2,4",
@"iPad2,5",
@"iPad2,6",
@"iPad2,7",
@"iPad3,1",
@"iPad3,2",
@"iPad3,3",
@"iPad3,4",
@"iPad3,5",
@"iPad3,6",nil];
BOOL isInList = [oldModels containsObject: thisPlatform];
return !isInList;
}
+ (NSString *)platform
{
size_t size;
sysctlbyname("hw.machine", NULL, &size, NULL, 0);
char *machine = malloc(size);
sysctlbyname("hw.machine", machine, &size, NULL, 0);
NSString *platform = [NSString stringWithUTF8String:machine];
free(machine);
return platform;
}
@end
检查触控 ID
- (BOOL)canAuthenticateByTouchId {
if ([LAContext class]) {
return [[[LAContext alloc] init] canEvaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics error:nil];
}
return YES;
}
您还可以找到用于检测 Secure Enclave here you find
