Abstract
A constrained device includes a processor; and memory storing program code that is configured to cause the processor to, responsive to a requirement for a private key for a function, perform operations on a plurality of seeds to obtain the private key; store the private key in the memory; and utilize the private key for the function. The program code is further configured to cause the processor to, subsequent to the function, remove the private key from the memory. The private key is for a quantum-safe algorithm. Advantageously, the present disclosure supports longer private keys for the quantum-safe algorithm, relative to existing algorithms, with limited resources in the constrained device.
