fir bhi anya kootlekhit protokaul, anadhikrut paathakon ke khilaaf gopaneeyata haasil karne ke prayaas mein hain, haalaanki ye protokaul abhi anusandhaan charan mein hain. RFID taig ko surakshit karne mein ek badi chunauti, taig ke bheetar kampyooteshanal sansaadhanon ki kami hai. maanak kootalekhan takaneek mein adhikaansh kam keemat vaale RFID upakaranon mein upalabdh sansaadhanon ki tulana mein adhik ki aavashyakta hoti hai. RSA security ne ek prototaaip upakaran ko peteint karaaya hai jo sthaaneeya star par ek maanak takkar parihaar protokaul ke dakhal se RFID sanketon ko jaam kar deta hai, or prayokta ko agar vaanchhit ho to pehchaan rokane ki anumati deta hai.[64] vibhinn neetigat upaayon ka bhi prastaav kiya gaya hai, jaise ki RFID taig waali vastu ko ek udyog maanak lebal ke saath chihnit karna. RFID suraksha, kuchh varshon se ek bahut sakriya anusandhaan kshetr hai, jismein 2002 se lekar aaj tak 400 se adhik vaigyaanik pepar prakaashit kiye gaye hain. is kshetr mein sandarbh ki ek vyaapak soochi RFID Security and Privacy Lounge mein pai ja sakti hai.

iski tulana mein atulyakaalik system ka design bahut kathin hota hai kyonki sabhi sambhav samay mein bhi sambhaavit state ka vichaar kiya jaana chaahiye. nyoonatam aur adhiktam samay ke table ke nirmaan ke sabse saamaanya vidhi ke anusaar ismein saare state vidyamaan ho aur vaise state ke mineemaaij ke liye sarkit ko samaayojit kiya jaata hai aur jo iske sabhi hisson ke susangat state mein samay-samay par jaane ke liye sarkit ko baadhya kare. (ise "self-reesinkronaaijeshan" kaha jaata hai.) aise saavdhaan design ke bina sanyogavash atulyakaalik laujik ka utpaadan karna aasaan hai jo "asthir" hai aur vaastavik electronics hai jismein apratyaashit parinaam hote hain kyonki electronic upakaranon ke moolyon mein chhote badlaavon ki vajah se sanchit vilamb hota hai. kuchh sarkit (jaise sinkronaaijr-flip flop, svich debaaunsar aur jo baahari anasinkronaaijd ko atulyakaalik laujik sarkit mein pravesh karne ki anumati deta hai) sahaj roop se apne design mein antarnihit atulyakaalik rahe hain aur is tarah hi vishleshan kiya jaana chaahiye.
kuchh pranaaliyon mein yadi digital deta ka ek bhaag lupt ho jaae ya galat tareeke se vyavahrut hon, to sambandhit deta ke vishaal khandon ka arth poori tarah se badal sakta hai. kyonki kleef ifekt ke kaaran, upayogakartaaon ke liye bataana mushkil hai ki koi vishisht system vifalta ke kagaar par sahi tha ya fir vah asafal hone se pehle bahut adhik shor ko sahan kar sakta hai ya naheen.
