Hi,
I am currently designing a authentication protocol in sensor networks. I
have defined the follwoing variables:
//on the sender side:
uint64_t hash=0;
uint8_t payload[8];
//break the 64 bit hash down into eight 8-bit paylaod for sending purpose
for(i=0;i<=10;i++){
payload[0]=(uint8_t)(st[i].hash>>56);
payload[1]=(uint8_t)(st[i].hash>>48);
payload[2]=(uint8_t)(st[i].hash>>40);
payload[3]=(uint8_t)(st[i].hash>>32);
payload[4]=(uint8_t)(st[i].hash>>24);
payload[5]=(uint8_t)(st[i].hash>>16);
payload[6]=(uint8_t)(st[i].hash>>8);
payload[7]=(uint8_t)st[i].hash;
}
when i compiled the code, there is no error.
===================================
//on the receiver side,
uint64_t receivedhash=0;
uint8_t receivedpayload[9];
receivedhash=(uint64_t)msdu[0]<<56
+(uint64_t)msdu[1]<<48
+(uint64_t)msdu[2]<<40
+(uint64_t)msdu[3]<<32
+(uint64_t)msdu[4]<<24
+(uint64_t)msdu[5]<<16
+(uint64_t)msdu[6]<<8
+(uint64_t)msdu[7];
when i compiled the code, i got the following error: I have tested the
different portions of code and make sure the problem comes from the above
piece.
hashtesting.nc:906: internal error: Segmentation fault

Anyone can help me out? I have tried the whole morning with no luck. Thanks
in advance.
