Abstract
Retrieving public keys in a memory constrained system is performed by generating a plurality of public cryptographic keys and private cryptographic keys using a cryptographic technique and characterizing each of the plurality of public cryptographic keys and corresponding private cryptographic keys into an associated first cryptographic component and a second cryptographic component. At least one relationship matrix, including the first cryptographic component of each of the plurality of public cryptographic keys and corresponding private cryptographic keys, is created based on predetermined rules. Subsequently, a first cryptographic component and a second cryptographic component of a private cryptographic key are received when a public cryptographic key is required, and the public cryptographic key is retrieved based on the first cryptographic component and the second cryptographic component of the private cryptographic key using the relationship matrix and the predetermined rules.
