...base and the size of a pointer *p* can be computed as the following: *size = 1 << e;* *base = p & ~(size -1);* BBC uses a contiguous array to implement bounds table. Each entry of this table stores the above single byte. Also, application memory is divided into aligned *slots* with *slot_size* bytes. The bound table has an entry for each slot. When checking whether a pointer is out of bound or not, BBC can enable optimized bounds checks. For instance,* p* is a pointer, we want to check whether the following pointer arithmetic is safe or not: q = p + i. An explicit bonds check is as the...

Since the vTPM implementations are being incorproated into Xen and possibly upstream Linux, I would like to see if this protocol change could be added before we have significant legacy implementations. If not, I still think it would be useful as either a v2 or negotiated protocol change. The current vTPM protocol is a copy of the network protocol. This was likely done for ease of implementation,
