According to the Nikkei, NTT is using reflected laser light for encryption. Random number sequences used in cryptographic systems are usually generated from mathematical formulae but by understanding the algorithms behind the formulae hackers can crack the encryption. Using irregular physical phenomena to generate random numbers can achieve a higher level of unpredictability. NTT has ...
