I fully agree... J3A081M can be found at 10$ over the WEB
Futhermore this class of cheap device can process TLS or DTLS as illustrated in https://tools.ietf.org/html/draft-urien-uta-tls-dtls-security-module-00 They could be used for numerous applications in the IoT Rgs Pascal 2016-07-23 23:59 GMT+02:00 Michael StJohns <[email protected]>: > On 7/23/2016 11:10 AM, Pascal Urien wrote: > > Hi All > > J3A081M is a javacard device from NXP > > The micocontroller should be the P5CD081V1A, which comprises a crypto > processor > > > There's a number of these from a number of vendors.
