DATA & ANALYTICS
quantum data security ,” he says . Upadhyay believes that “ post-quantum cryptosystems will find widespread adoption among organisations ,” thereby creating significant economic opportunities for security firms specialising in this area . He also notes that transitioning from RSA or ECC-based systems to alternatives that are secure against quantum attacks is not only “ economically viable ” but also “ less technically demanding .”
Millard warns that while defenders will have better technologies , “ attackers will get smarter and more automated .” He points out that the time required to decrypt data will dramatically decrease , going “ from weeks or months to hours or seconds .” However , Millard is quick to add that data secured by quantum-level encryption will remain robust .
Cheng highlights the disparity between the development of quantum computers and quantum security , especially in terms of funding . However , he observes a positive change , particularly in government action . “ The US has now firmly taken the lead following a series of orders and legislation ,” he states , referring to the Quantum Computing Cybersecurity Preparedness Act and the recent 2023 US National Cybersecurity Strategy . Cheng also mentions the National Institute of Technology ’ s ( NIST ) global competition to develop new algorithms , stating that “ four have been shortlisted and are on track to be standardised ,” which many see as the catalyst for post-quantum migration . “ The truth is that post-quantum migration can and should have begun earlier . Especially with the threat of HNDL attacks , everyone is playing catch-up . It ’ s not too late , but the next few years are crucial for the future of data and information security .”
