Digital signatures are a vital part of the digital world. The trust factor in the digital world is ensured with a digital signature. Over the evolution, the purpose remained constant, but the applicability and frontier continued to evolve, thus raising the demand for continuous performance, security level and computational improvement. Especially with emerging IoT, blockchain and cryptocurrency, the digital signature security level and performance improvement demand continue to rise. A digital signature scheme (DSS) is used to generate signatures. This paper investigates the widely used elliptic curve digital signature algorithm (ECDSA) and its application to blockchain and IoT. Then, we performed an empirical comparison of ECDSA with the Edwards curve digital signature algorithm (EdDSA). The study concludes by showing that EdDSA is superior to ECDSA and can be applied in blockchain and IoT domains to reap immediate benefits.Povzetek: Avtorja primerjata dve metodi generiranja varnih digitalnih podpisov in pokažeta, da je EdDSA boljša kot ECDSA.

A digital signature is essential for verifying people's reliability and data integrity over networks and is used in web server certificates, authentication, and blockchain technologies. Specifically, to solve the bitcoin scalability problem, Multi-Signature (MS) schemes have recently attracted attention because the MS's aggregate algorithm can reduce the amount of signature data in transactions. While such schemes support only a single message signing, Interactive Aggregate Signatures (IAS) and Aggregate Multi-Signature Protocol (AMSP) support signing of multiple messages. However, there are some issues with these schemes, for example, key aggregation is unavailable. In this paper, we propose a key aggregatable IAS scheme called KAIAS that can sign multiple messages with key aggregation. In terms of cases using Multi-Signature, previous studies have mainly discussed the benefits of reducing the size of signatures. On the other hand, we also propose a practical application of KAIAS that leverages its benefits in aggregating both signatures and public keys with a low computing cost for verification.
