Abstract: Systems and methods for providing accelerated passphrase verification are disclosed. In one embodiment, a method includes receiving a full security string, generating a full security string hash code, storing the full security string hash code in a memory, determining at least one substring based on an entropy value associated with one or more leading characters in the full security string, generating at least one substring hash code and at least one corresponding character count value, such that the corresponding character count value equals a number of characters in the at least one substring, and storing the at least one substring hash code and the at least one corresponding character count value in the memory.

Abstract: Electronic devices are adapted to facilitate execution of software signed by more than one entity. According to one example, an electronic device can store software including a hash table segment. The hash table segment can include at least one hash entry, a first signature and first certificate chain from a first entity for the at least one hash entry, and a second signature and second certificate chain from a second entity for the at least one hash entry. The electronic device may validate the first and second signatures. If both the first and second signatures are validated, the electronic device can execute the software. Other aspects, embodiments, and features are also included.
